Regeneration

The HEA-ELR9000 series of electronic DC loads with mains recovery offer many voltage levels up to 1.500 V, currents up to 510 A and powers up to 15 kW for the most diverse range of application. The loads are available in four typical control modes CC, CV, CP and CR and can be extended for higher power. The HEA-ELR 10000 series already offers 30 kW in only 4 U.

Flexible power stage

The DC input range is extremely flexible and allows the use of high input voltages or optionally high input current within the respective nominal power. For comfortable operation, this series has a high-resolution, intuitively operated TFT touch panel with integrated function generator and predefined curves as well as larm manager, memory and storable user profiles.

Measurement and display

The display resolution is 4 digits, which can be set in the range of 0…100 Adjustable DC input parameters (U, I, P, R) have a high accuracy and stability and are very dynamic (current pulses up to 30 µs). For remote operation the devices are equipped with a potential-separate analogue interface (0…5 V / 0…10 V) and USB. Further interface options such as CAN, CANopen, Ethernet, Profibus/net, RS232 or Modbus can be retrofitted via the plug & play slot on the backside of the panel. This device series is an indispensable tool for the reproducibility of test results
and is suitable for integration into professional automated test benches and for cascading for high-load applications. The efficient mains recovery function converts the supplied DC energy into a mains-synchronous sinus current and put it back into the AC mains. Thereby achieves an efficiency of up to 94.5 %. This reduces the usual heat generation of electronic loads.
