EPS/TSDCR Regenerative bidirectional Testsystems 60kW-1,3 MW

Source - Sink - Battery Charger/Tester/Simulator - Inverter - up to 1300kW/kVA from EPS Stromversorgung

The coordinated test systems EPS/TSDCR from EPS Electronic Power Supplies are for tests accompanying development, such as simulation of the on-board grid, simulation of energy storage devices (e.g. LiIon battery simulation), tests of electrical drives as well as fuel cells and their corresponding components such as inverters, batteries (charging and discharging) and switch suitable. The outputs go up to 650kW in a voltage range from 5 to 1000V and a current range up to 1000A.

The special feature of these systems is that the electrical energy consumed in generator mode is fed back into the grid with high efficiency. External loads (resistors) are thus superfluous and electrical energy that is otherwise "burned" can be returned profitably. This feedback capability is a decisive factor in most test applications, as unusually high outputs are used here. Either parallel connection (up to 2000A) or a multi-channel system (up to 4000A) is possible to increase performance. In contrast to conventional DC sources, the multi-channel system has two or four independently usable output channels and can work both as a source and as a sink.

All systems have an isolated output and a TFT touch panel for entering or displaying values and alarms.

They can also be controlled via CAN, MOD-Bus, SCPI / TCP-IP, VNC and optionally via RS232 / USB, HighSpeed /Analog, HighSpeed CAN, Profibus, Profinet and Ethercat.

The test system can be freely programmed and has specific algorithms that enable a wide variety of tests such as testing solar systems (inverter option), super capacitors and reactive power compensation.

Comprehensive protective measures, such as an event memory integrated as standard and a safety control (level "d") round off the concept.

The system can be "upgraded" customer-specifically, e.g. with insulation monitoring, an additional discharge unit in the event of a power failure (simulator operating mode), a power distribution unit, impedance measurement (tester operating mode) or water cooling (IP54).
