MODULE DERATING

The output rating of Multistax® modules is dependent on two factors, location within the chassis and ambient temperature according to the table and derating curves below. For correct application the resultant derating should be applied to each affected module before applying the overall chassis derating shown later in this datasheet.

Output Power LimitImax

Power Limit ZoneMultistax® modules have a several of levels of protection to ensure that power supply is not damaged if used under overload conditions. When the output voltage setting (Vset) is less than or equal to the nominal setting (Vnom), the current limiting is at the current limit set point. However if Vset is greater than Vnom, the output power is limited to ensure that the module does not exceed its power rating.

For example, Mx4 is adjustable between 12V and 30V. Imax is 10A. Power rating is 240W. At 24V the module can deliver 10A continuously, i.e. 240W. At 30V, the module can still deliver 240W, 8A continuous.

MODULE CURRENT LIMIT PROGRAMMING

A variety of over current protection methods are possible with theMultistax® modules. Modules type Mx1 to Mx5 can be programmed for Straight-line current limiting or Foldback current limiting while Mx7 employs only Straight-line current limiting. Simple external application circuits may be used to achieve programmable foldback current and user programmable reduced current limit levels. See the Multistax® Designers Manual for full details.

The default current limit characteristic is Straight Line Current Limiting.

Voltage Adjustment - LocalThe multi-turn potentiometer that adjusts each output within the specified range may be accessed via the output panel of the power supply. Clockwise rotation increases output voltage. Resolution is approximately 5% of nominal voltage (Vnom) per turn.

Voltage Adjustment - Remote (resistive / electronic)The output voltage may be adjusted or trimmed by means of an external resistor or potentiometer network connected to the Vtrim pin on the J3 connector on the module. Linear Electronic programming is also possible and may be implemented according to the formula Vout = K Vcontrol. See Powerstax MS1U series Designers’ Manual for full details.

Parallel OperationTo achieve increased current capacity, simply parallel outputs using the standard parallel links. Powerstax ‘wireless’ sharing ensures that current hogging is not possible.

Serial OperationTo achieve increased output voltages, simply series outputs using standard series links, paying attention to the requirements to maintain SELV levels if required in your system.

Remote SensingWhen the load is remote from the power supply, the remote sense pins may be used to compensate for drops in the power leads. Where the power cabling contributes significant dynamic impedance, see MS1U series Designers’ Manual.

Current Limit AdjustmentThe output current limit setting may be adjusted (downwards only) by means of an external resistor connection to the Itrim pin on the J3 connector on the module.

Bias Voltage (Located in chassis)A SELV isolated 5V (always on) bias voltage rated at 500mA (30mA MS1U-6E & MM1U-6E) is provided on J2 to facilitate miscellaneous control functions.

Inhibit/EnableInhibiting may be implemented either globally or on a per module basis (Power Unit or Power Module inhibiting). Reverse logic (Enabling) may also be implemented, see MS1U series Designers’ Manual.

AC FailOpen collector signal indicating that the input voltage has failed or is less than 80Vac. This signal changes state giving 5mS of warning before loss of output regulation. See MS1U series Designers’ Manual for full specifications.

Indication LEDsEach Power Module has a visual indicator to identify that it is operating within normal ratings. Very useful for system diagnosis.

Connecting to Capacitive LoadsWhen connecting Multistax® units to capacitive loads external blocking diodes of appropriate current capacity must be used.

Standard parallel links can be supplied.To order, please use part number MP1.

Standard serieslinks can be supplied.To order, please use part number MS1.
