The EPS/ELR programmable load with energy recovery (i.e. mains feedback)
offers new voltage up to 1500V,
currents up to 510A at power ratings with 10,5kW and expandable with more than 200kW on request.
The unit incorporate the four common operation modes Constant Current / Resistance / Voltage / Power
and are used for a multitude of applications.
The FPGA based control circuit provides additional features like a function and arbitrary generator,
a table based regulation circuit for the control of dynamic load profiles or the simulation of non-linear
internal resistances, like the ones of batteries or LED chains.
Electronic Load with energy recovery
| Model | Description |

| EPS/ELR | Electronical Load with energy recovery |
The energy recovery function converts the supplied DC energy into a synchronous sine current and feeds it back into the local or public grid. In common systems, the energy from burn-in tests and battery capacity
tests is radiated into the environment.
This energy can be recovered with this unit.
The big blue LCD resistive touch panel offers a different and intuitive kind of manual handling compared to other devices. Response times for the control via analog or digital interfaces have been improved by the DSP
controlled hardware. During parallel operation, a Share bus is used to balance the load current between the
single units.
For the remote control there are already two interfaces built-in (1x analog, 1x USB), which can also be extended by optional, pluggable and retrofittable, digital interface modules for RS232, RS485,
CANopen, Ethernet and Profibus.
The front side USB port is for USB sticks, in order to load and save profiles.
Further options are supervision unit 3-phases (AIU, ENS) »EPS/ELR ENS (BISI)« as well preconfigured
cabinet systems.
