EPS/TSDCR Regenerative DC Load System 60kW-2,6MW

Source - Sink - Battery Charger/Tester/Simulator - Inverter - up to 2.6MW from EPS Stromversorgung

The EPS/TSDCR calibrated test systems from EPS Power Supply are suitable for development-related tests, such as tests of electric drives and fuel cells and their corresponding components, batteries (discharging/charging) and switches. The power ratings go up to 650kW (in parallel connection) in a voltage range from 5 to 1500V and a current range up to 1200A.

The special feature of these systems is that the electrical energy absorbed in generator mode is fed back into the power supply grid with high efficiency. External loads (resistors) are therefore superfluous and electrical energy that would otherwise be "wasted" can be fed back profitably. This regenerative capability is a decisive factor in most test applications, as unusually high power levels are used here.

To increase performance, either parallel connection (up to 4800A/2.6MW) or a multi-channel system (up to 9600A) is possible. In contrast to conventional DC sources, the multi-channel system has two or four independently usable output channels and can operate both as a source and as a sink.

All systems have an electrically isolated output and a TFT touch panel for entering or displaying values and alarms. They can also be controlled via CAN, MODbus TCP (Ethernet), VNC and optionally via HighSpeed/Analog, HighSpeed CAN, Profibus, Profinet and Ethercat. Programming languages are optional: LabView, MatlabSimulink and SCPI.

The system can be freely programmed and has specific algorithms that enable a wide range of tests such as battery tests, testing of fuel cells and solar systems (inverter option), DC electric motors, supercapacitors and power factor correction.

Extensive protective measures, such as an integrated event memory and safety control (level "d") as standard, round off the concept. The system can be "upgraded" to customer specifications, e.g. with insulation monitoring, protective diode for safe sink operation, DC contactors for disconnection under load, power distributor, energy meter or water cooling (IP54, incl. at 300/600kW).
The systems are CE-certified and can optionally be adapted to UL.

Further options on request, as well as higher voltages and currents.
