Read the rating labellocated on the power supply to verify that the unit has the correct input and output ratings and

REV C Page 7 of 17

part number. All electrical tests performed on the unit prior to installation must be carried outby a qualified person familiar with AC/DC powered equipment and having the specializedknowledge required of the hazards associated with switched mode power supplies. This isparticularly essential if the unit covers are removed, which exposes many devices operating atline voltage and some operating at peak voltages of up to 400 volts.

MOUNTING REQUIREMENTS AND COOLINGThe mechanical outline drawing, contained within this pamphlet, provides the necessaryinstallation dimensions required for customer mounting and space allocation.

IMPORTANT: Use M4 screws for mounting. Screws must not penetrate more than 1/8”(3MM) into the power supply. The UF1500 units have integral cooling fans and can be mountedin any position. However mounting orientation should not oppose the system forced airdirection, the natural convection, or system cooling draft air flow. Furthermore, the powersupply air intakes and exhaust slots must not be obstructed. The intake air temperature shouldbe limited to allow the unit to operate in accordance with the thermal derating envelope of theelectrical specifications.

INPUT POWER CONNECTIONSThe input power terminal block is located on the chassis end that also includes the fans. Safety earth ground is to be connected to the grounding post adjacent to the input powerterminal block.

The terminal functions are clearly shown on the top label of the unit.

Connections should be made using correctly sized wire gauges and colors as per applicableelectrical codes.

AC INPUTLine: BlackNeutral: WhiteGround: Green

The ground connection must be made to a well defined, low impedance ground (protectiveground). Connections must not have loose strands and the insulation must cover the wire upto the block itself. Interface terminal lugs must be fastened properly.

AC INPUT AND OUTPUT POWER RATINGS

85-265 Vac, 47-63 Hz. The input current will be limited to 20A max.

EMI(Conducted)

The UltraFlex power supply has internal EMI filtering, and complies with EN55022 level B, aswell as FCC Docket 20780 Part 15, Subpart J Class A. The end system wiring and groundingcan influence the conducted and radiated EMI pattern. The customer may require additionalEMI filtering to meet system requirements. If problems are encountered, the customer shouldcontact Lambda’s Application Engineering Staff.

INPUT TRANSIENT/ESD PROTECTIONThe UltraFlex is designed to withstand surges, line transients, and ESD as specified in thefollowing documents:

Surge: IEEE-C62.41, Category A3;EN61000-4-5 Class 4; L-L: 2KV, L-Gnd: 4KV, Criterion B.

Fast Transients: EN61000-4-4, Level 3, Criterion B.ESD: EN61000-4-2, Level 3, Criterion B.Input Dips and Variations: IEC1000-4-11, Criterion B.Radiated Immunity: EN61000-4-3, Level 3, 10 V/M.

REMOTE SENSERemote sense is provided for each output to compensate for load cable drops from the powersupply to the sense points. To meet specifications and output voltage set point of the outputmodules, the sense lines must be connected to the load or locally to the power supply outputterminals. The remote sense connections are available on the signal connector. See Table 2below for the appropriate pin numbers.

Table 2Single Output Modules Dual Output Modules

J1 pin 1 + Positive Remote Sense J2 pin 2 - Negative Remote Sense Output 1J1 pin 10 – Negative Remote Sense J2 pin 3 +Positive Remote Sense Output 1

J2 pin 4 +Positive Remote Sense Output 2J2 pin 5 - Negative Remote Sense Output 2

The following rules should be observed when using remote sense:

1) Use a twisted pair of 20-24 AWG wires for remote sense leads.2) Route the sense leads away from any high current conductors or devices

(motors, transformers, etc.) to avoid pick-up, as this may cause ripple or stabilityproblems on the power supply.

3) Never disconnect the power supply output power connections with the remotesense still connected to the load. This may damage the internal remote sensepick-up resistors.

4) The total voltage drop on the output cables must be limited to less that 0.5V.

REV C Page 9 of 17

OUTPUT VOLTAGE ADJUSTMENT (TRIMMING)Voltage adjust potentiometers are provided for all outputs. The potentiometers are locatedadjacent to the output connections of the power supply. Use a non-conductive trim-potadjustment tool. Turn clockwise to increase the voltage. NOTE: Always monitor the corresponding output voltage while turning the potentiometer.

CURRENT LIMIT PROTECTIONAll outputs are protected by constant-current limiting circuitry. The overcurrent limits are set atthe factory between 110-150% for single outputs. The overcurrent limit settings for the dualoutput modules are as follows: Output #1: 110- 150% of rated load; Output #2: 110-150% ofrated load. Removing the overload automatically restores the output voltage. On Dual OutputModules - if Output #1 is in current limit, Output #2 voltage will also decrease.

OVERVOLTAGE PROTECTION (OVP)When any single output module voltage reaches 120-130% of nominal voltage, that channelwill shut down. When any dual output module reaches 120-140% of nominal voltage, bothoutputs of the dual module will shut down. OVP on 2V outputs is factory set to 3-3.5V, andOVP on 3.3V outputs is set to 4.3-4.8V. OVP activates the internal shutdown latch of themodule until the AC input power is recycled OFF to ON to clear the latch and resume normaloperation, once the OVP problem has been corrected.

OUTPUT LOAD REGULATION(NO LOAD/FULL LOAD/NO LOAD) Single output modules 0.4% maximum.

Dual output modules 0.8% maximum.

OUTPUT LINE REGULATION(85-265VAC 47-63 Hertz) Single output modules 0.1% maximum.

Dual output modules 0.2% maximum.

HOLD UP TIME AFTER POWER LOSS(AC INPUT)The UltraFlex output voltages will remain within specified regulation for a minimum of 16msecafter loss of applied power on the AC input at full load and nominal output voltage.

TURN-OFF/TURN-ONTurn-off/turn-on output voltage - transient overshoot is less than 3% of nominal voltage duringthe application or removal of input voltage under any condition of turn-on, turn-off, includinginhibit or enable.

TURN ON TIMEAll outputs shall be within voltage regulation limits within 1 second of application of AC power.

NOISE AND RIPPLEUltraFlex output modules meet the following specifications with a 20MHz bandwidth. Caremust be taken when conducting the following measurements: Single output modules: 2-5V, <1000W: <50mV pk –pk.

</= 5V, 1000W: <200mV pk-pk directly on the output terminals; <50mV pk-pk measured 5 inches away from the output

terminals with two – 2700 uf capacitors located at this point. > 5V: <1% pk–pk.

REV C Page 10 of 17

Dual output modules: <1% pk-pk.

DYNAMIC LOAD TRANSIENT RESPONSEA 25% step load change will result in an output deviation (overshoot or undershoot) of lessthan 3% of nominal output voltage (150mV for <5V outputs, 400mV for the </= 5V 1000Wmodule). Output voltage will recover to within 1% of set value within 300�s (500us for the</=5V 1000W module.) Slew rate not to exceed 1A/us.

DYNAMIC CROSS REGULATIONThe effect of dynamic cross regulation on any fully loaded auxiliary channel for a load stepchange of 25% from a 75% base value on the highest rated channel, at a slew rate not toexceed 1A/us, shall be less than 0.1% for single output modules and less than 3% for dualoutput modules. The summation of the individual module powers must not exceed the totalrated power of the UF1500. This measurement is to be performed with all other channelsloaded to 50% of rated load.

TEMPERATURE COEFFICIENTThe output voltage will change less than .02% per oC over the ambient temperature range of0-50oC. (After 30 minute warm-up).

NO LOAD OPERATIONOperation at no load will not cause damage to the UltraFlex supply, however the outputvoltages may be outside the regulation band. A 1 Ampere preload is required on the highestrated output for a dual output module.

OVER TEMPERATURE SHUTDOWNThe power supply is self-protected against over-temperature conditions. A thermal shutdownrequires re-cycling of the input voltage to restore output. The fan will continue to operateduring thermal shutdown.

OPERATING ENVIRONMENTThe power supply is designed to meet the performance parameters defined above whenoperated within the following conditions:

Temperature: 0 to 50o C; -20oC Start-Up, 30 Minutes to performwithin specifications.

GLOBAL SIGNALSThe following signals are provided as a standard feature on the UF1500 via J3. Logic levelsignal outputs are via open drain Mosfets (60VDC/100mA max ratings). Pull up resistors arerequired. Signals are referenced to the Signal Common terminal (J3 Pin 3) on the interfaceconnector.

5V DC Standby Output (J3 pin 1):Isolated 5VDC/0.3A output available whenever the input power is applied. This output is notaffected by inhibit signals. Load regulation less than or equal to 5%.

Global Output Good LED Drive (J3 pin 2):An open drain output to light an external LED indicator. If any output equipped with a DCoutput good option fails, this signal goes low. An internal 390 ohm series resistor limits thecurrent through the LED.

Global Output Good (J3 pin 4):When all output modules which have Output Good signals are within specification, this signalis high. If any output fails, this signal goes low.

REV C Page 12 of 17

Fan Stop/Thermal Alarm (J3 pin 5):Logic signal goes low if the fan stops; or in the event of overheating, at least 10mS prior to athermal shutdown of the supply. Signal remains low until fault is cleared. If a thermal shutdownhas occurred, the input power must be re-cycled to restore output.

Input Power Fail Signal (J3 pin 6):Following the loss of input power, this signal provides at least 5mS warning prior to any outputgoing outside of it's regulation band when adjusted to Vo nominal at full load. The signal goes"Low" when input power is lost. Signal "High" on fault available as a special option.

Global Inhibit (J3 pin 8):A TTL compatible signal will turn off all output modules, depending upon the setting of theInhibit/Select function (See below.) The outputs are less than 0.5V while inhibited at no load.

Inhibit/Select (J3 pin 10):When open circuit, Global Inhibit is Active Low. When this input is shorted to signal common(Pin 3), Global Inhibit is active high.

OUTPUT MODULE SIGNALS & FEATURESOutput module options are available only with single output modules. Logic Level signaloutputs are via open collector NPN transistors (40VDC/10mA max ratings) except the ModuleInverter OK signal which is 20VDC/4mA. Pull up resistors are required. Signals are referenced to the -Remote Sense terminal. (J1 pin 10)

+Remote Sense (J1 pin 1- single output module, J2 pin 3 & 4 – dual output module):Compensates for load cable drop from power supply to sense point (.25V per terminal.) Tomeet regulation the remote sense must be connected to the load or locally to the powersupply.

Remote Voltage Adjust (J1 pin 2):This input signal may be used for remote adjustment of the output +/- 10% of nominal viaexternal resistive or current input. Requires external potentiometer (10K ohms) between +/-remote sense terminals with the wiper to remote voltage adjust pin.

Margin (J1 pin 3):Margining +/- 5% of nominal output voltage. Requires an external switch (normally open,SPDT) connected to the +/- remote sense terminals with switch common connected to Margininput.

Current Sharing (J1 pin 4):Active current sharing provides Load Sharing between two or more similar output modules towithin 10% of each output’s rated current. The current share node automatically disconnects ifa module inverter fault is detected. Modules with this option share current proportionally totheir maximum current ratings. Current sharing between modules is accomplished byconnecting J1 pin 4 of each module together. A single remote sense point must be used. Theindividual output voltages must be set to within 1% of each other to ensure the outputs arewithin a 2% capture window. Refer to Lambda application note AN-018 for additional details.

High Module Signal (J1 pin 5):When outputs are connected in parallel and the current share option is employed, only themodule with the highest output voltage will have a logic high signal (useful for systemdiagnostics). This is an open collector output signal.

REV C Page 13 of 17

Inhibit Module (J1 pin 6 - single output module, J2 pin 1 - dual output module):A TTL "low" level signal can be applied to disable outputs to <0.5V at no load.

Output Good Signal (J1 pin 7):This signal goes low if output deviates by - 4% from factory settings.

Module Inverter O.K. Signal (J1 pin 8):If an output module inverter fault is detected this output goes high. This signal causes thecurrent-share node to disconnect. Maximum ratings for the output transistor are 20V/4mA.

Current Monitor (J1 pin 9):This is an analog signal proportional to the output current, 0-2VDC (2VDC at max outputcurrent). From 20%-100% of current rating the accuracy will be within 10% of the max ratedcurrent value.

-Remote Sense (J1 pin 10 –single output module, J2 pin 2 & 5 – dual output module):Compensates for load cable drop from power supply to sense point (.25V per terminal.) Tomeet module specifications the remote sense must be connected to the load or locally to thepower supply.
