Power: 500W … 25200W Voltage: 60V - 120V - 300V - 600V Current: 30mA … 2700A Operating Modes: Current CC Resistance CR Voltage CV Power CP Adjustable limits for: Maximum current Minimum voltage Cooling: Air-cooled / liquid-cooled, current and power-controlled Analog interface: Standard (Fully isolated option) Parallel connection: up to 3 devices, Master-Slave operation possible Data interfaces (optionally): RS232 (SCPI) IEEE488 (SCPI) USB (Virtual COM Port) RS485 (Binary Protocol) Multi-channel systems all devices can be combined

The electronic loads of the series ZS are optimized for the practical use in laboratories, manufacturing and quality control. Besides the air-cooled version there is a liquid-cooled variant for high power available. The devices are provided in the four voltage classes 60V, 120 V, 300V and 600V. The power spectrum contains models from 500W up to 25200W and currents up to 2700A. On request we manufacture units with higher power. Because of the high current ranges the device supports a very wide power spectrum. The ability to accept a short-term overload can allow the use of a lower rated, and lower cost load than it would be the case with more limited, or no overload capability. Extensive equipment options support an optimal adaptation to test projects. For example, different interfaces can be used as plug-ins to replace or upgrade the existing interface. Multi-channel systems are easy to build. The ZS Loads have a built-in analog interface as standard. A fully isolated version is optional. They have excellent dynamic characteristics, and are ideal for pulsed loading applications. The robust mechanical housing is intended for either 19” rack mount or benchtop use. The larger, higher power devices can be supplied directly mounted on castors.

Special Ranges: For an adaptation to your needs the devices can be equipped with special setting ranges. We recom-mend to match the ranges to the real requirements.

Current: Devices of the same power can be optionally equipped with the current range of the higher volt-age classes.

Voltage: For applications with very low voltages (e.g. testing of fuel cells) the devices can be equipped with a reduced voltage range, e.g. 2V, 5V ,10V or 20V.

Devices with 3 or 4 switchable ranges are very flexible in

appliacation

Operating Modes

The electronic loads of the series ZS support the four operating modes constant current, voltage, power and resistance. Depending on the operating mode, additionally a limit for the allowed maximum current or minimum voltage can be set. Full/reduced Setting and Presetting Function For increasing the resolution every device provides additionally to the full setting range a setting that is reduced to 1/3 of the rated current. The load can be set without being connected to the unit under test. In this case the display shows the values directly in Amps, Ohms, Volts or Watts. Operating Range The operating range is de-termined by the minimum input voltage as well as by the maximum current and the power of the device. The permissible power is dependent of the device temperature and can be a multiple of the nominal

power, depending on the model.

Dynamics and Controlling Time The built-in modulator sup-ports two independently adjustable currents and times of 100µs … 1s. The controlling speed of the devices can be adapted in three steps (fast/medium/slow) to the behaviour of the unit under test. Voltage Switching For switching voltages without overshoot a trigger volt-age can be set. The current is only released if the input voltage is higher than the trigger voltage. Using this feature, also PWM voltages can be loaded.

Remote Control All functions of the load can be remotely controlled us-ing the analogue I/O connector. The controlling inputs can be operated using TTL level and 24V of PLC con-trollers. Optionally (ZS06) the analog connector can be fully isolated from the load input. Analog Control In the operating modes CC, CV and CP the setting value can be preset with 0…5V or 0…10V DC.

Interfaces (Accessories) Uniquely the ZS Series has slots for 3 digital communi-cations interfaces, and 3 analog interfaces or acces-sory cards. These can be ex-changed or upgraded as required. This gives the ZS Series huge application flexi-bility. The following inter-faces are available: • RS232 + USB 1) (Option ZS01) • IEEE488 + RS232 + USB 1) (Option ZS02) • System Interface (Cable) (Option ZS04) • System Interface (Fiber Optic) (Option ZS05)

1 Controllable as Virtual COM interface under Windows 98/ME/2000/XP

The interfaces allow the use of additional features of the loads, e.g.:

• Programmable load curves • Dynamic load changes with wide setting

ranges • Data acquisition • Trigger functions • Using the provided software tools and LabVIEW drivers

For economical control of multiple load systems the sys-tem interface cards (ZS04) can be used. The first load interface (RS232/IEEE/USB) controls the system interface bus. Each interface is completely isolated from the oth-ers. In difficult EMC situations a fibre-optic communica-tion version (ZS05 )is available to be used instead of the wire-connected version. Programming syntax is SCPI.

Analog Monitor Outputs For voltage, current and power analog measuring sig-nals 0…10V are provided. The GND connections may float ±2V against the negative load input. Full galvanic isolation is optionally available (option ZS06). Cooling The devices are air- or liquid cooled*. For keeping the operating noise low, the controlling of the fans is de-pendent on power and current. For better exploiting the maximum possible overloads, the fan can be set on full capacity. * liquid-cooled devices page 20 Mechanics The series ZS is manufac-tured in robust 19” rack mount case which are also suitable for benchtop use. At the top of the device there are retractable handles. For heavy devices castors can be mounted. For 19” fitting no separate kits are needed. Terminals All connections are provided at the rear of the device. The current connections are heavy duty copper bus bars with bolts. All devices with input voltages higher than 60V must be installed with termi-nals made ‘touch safe’. For safety in benchtop applica-tions, all devices with high input voltages and currents up to 250A can optionally be equipped with MC safety connectors (Option ZS10).

Galvanically insulated Analog Interface (Option ZS06) If there are potential differences between GND of the load and the signals at the analog I/O connector, the standard analog I/O card can be exchanged against an insulated version. All measuring and controlling signals are connected via insulating amplifiers and optocou-plers. The card is compatible to the pins of the analog I/O standard socket. The insulating voltage is 500V DC against input -.

Power I/O Board (Option ZS07) The Power I/O Board can be upgraded for controlling external equipment. Via the interface of the load, 8 re-lay contacts (make contact 125V/1A) can be triggered and 8 logic inputs (5V … 24V, common GND) can be queried. Outputs and inputs are insulated from the load input. The insulating voltage is 500VDC against input -.

Castors (Option ZS09) For heavy devices castors can be fitted for an easier trans-portation. By using these cas-tors often the fitting in a 19” rack can be avoided.

Touch-Protected Load Inputs (pluggable) (Option ZS10) Devices for touch-dangerous voltages can be equipped with touch-safe safety connec-tors for currents up to 250A. The cable (up to 70mm²) is clamped without tools in the connector. The connectors can’t be mixed up. Two connectors with 2m cable each are provided.

Factory Calibration Report (Option ZS11) For all devices a Factory Calibration Option is avail-able. The repatriation to international norms is possible. The recommended calibration interval is 1 year. On request we can do the annual calibration.

————–—–———– Hardware Extensions——————–—–

Zero Volt Option (Option ZS12) The Zero Volt Option extends the operating range of the electronic load up to complete short circuit. It even can compensate voltage drops at the load lines of 1V. The Zero Volt Option is optimally suited for testing fuel cells in connection with adapted measuring ranges. The available Zero Volt Options are listed in the Techni-cal Overview. The fitting of a Zero Volt Option increases the housing for some devices. The load capacity is reduced by ca. 3V x the set current. When a Zero Volt Option is installed there is no protec-

tion against reversed polarity and no mains voltage selection.

Extended operating range with Zero Volt Option power reduction = 3V * set current

Optional Safety connectors

Castors

Analog I/O Extension (Option ZS08)

The analog I/O Extension board provides additional control inputs for the analog setting of the trigger volt-age and the current limitation. Further on the board has three relay outputs which are activated with the “Trigger Voltage”, load “Input on” and the “Overload”. The signals are insulated from the load input. The insulating voltage is 500VDC against input -.

Status Driver (Option ZS14)

The status driver contains an amplifier for the signals „Input on“, „Overload“ and „Trigger Voltage“ up to 30V/0.5A in an external connector housing. There is a power supply 5V … 30V required.

RS232 Interface (Option ZS01) Option ZS01 extends the device with an RS232 inter-face and a USB connector (as virtual COM interface). The programming is in SCPI. Inclusive 2m RS232 cable.

IEEE488 Interface Extension (Option ZS03) A device with existing RS232 interface (Option ZS01) may be updated to IEEE488 interface by plugging in the ZS03 option.

The plug-in interfaces provide additional or extended functions:

• Programming in SCPI • Settings with 16 bit resolution • Measuring function for voltage, current

and power • Programmable load profiles • Dynamic operating with variable current

rise and fall time • Measurement data storage

———————–—––– Data Interfaces——–-—–—–——–—

IEEE488 + RS232 Interface (Option ZS02) The IEEE488 (GPIB) interface also includes the RS232 interface (Option ZS01).

System Interface Cable (Option ZS04) (ZS04-M for master device, ZS04-S for slave devices) For building multi-channel systems further loads can be connected to the master device using the system interface. The master device is equipped with system interface ZS04-M and the slave devices with ZS04-S. Then all devices are programmable using the interfaces of the master device. For the connection a standard LAN cable is used. All inputs are fully insulated from each other. Inclusive 1m cable.

System Interface Fiber Optic (Option ZS05) (ZS05-M for master device, ZS05-S for slave devices) For distances above 3m, and 3 or more devices, the system interface should be the fiber-optic one which can be simply exchanged for the cable-connected version ZS04. Fiber optic connection is also recommended in high EMC interference situations. ZS05 includes 5m fiber optic cable.

Order example for 3 loads, master with RS232, cable connection to slaves: Load1 + ZS01+ ZS04-M, load 2 + ZS04-S, load 3 + ZS04-S

Exponential Inrush Current When switching the voltage to the Electronic Load an exponential-shaped current with variable time constant is generated. Peak current, continuous current and time constant (min. 2ms) are pro-grammable.

Battery Capacity Test A battery can be discharged in any operat-ing mode to the set dis-charge volt-

age. When the discharge voltage is reached the current is switched off. The Electronic Load measures the Ah and Wh. For recording the discharge curve the measuring function can be acti-

vated simulta-neously.

Liquid Cooling Liquid cooling allows a very effective removal of the heat energy without heating up the environment.

The noise is also very low. Liquid-cooled loads are there-fore especially used in areas where corresponding air cooled versions cannot be applied because of heat and noise. The size is also smaller. Cooling Medium Water is used as cooling medium also with additives of antifreezing compound (Glycol). The consumption of the cooling medium is controlled depending on the power input. In standby the cooling medium is stopped. The maximum temperature of the cooling medium for nominal power is 15°C. At higher temperatures a power derating has to be taken into account. At lower temperatures than 15°C a smaller amount of cooling medium is needed. To supply the unit with sufficient cooling medium a pres-sure of 3 bar is required at the liquid input.
