EA-PSB 2000 Triple Series

3-channel Programmable Bidirectional DC Power Supply

The electrification of the world is rapidly advancing, with industry and the public sector transitioning from fossil fuels to electrical energy, ideally sourced from renewables. Various requirements come together here: more power, more throughput, more flexibility.

As a new generation 3-channel bidirectional power supply the EA-PSB 20000 Triple allows synchronized testing to meet these requirements. It comes as a 3U and 4U version with a voltage range of up to 3 x 920 V and current up to 3 x 340 A.

3U version

3 x 5 kW
60 – 920V
20 – 170A

4U version

3 x 10 kW
60 – 920V
40 – 340A
Volitelně s vodním chlazením

Key features:

With three independent channels, customers can conduct parallel testing on different components or subsystems, such as motors, inverters, and on-board chargers, within the same test setup.
The occupation of rack space is reduced by more than 50% when using triple devices instead of single output devices.
Operational expenses are significantly lower due to high energy recovery (up to greater than 96%) when used in bidirectional mode.
Voltages from 0 – 60 V up to 0 – 920 V.
High performance with up to 10 kW per channel.
Currents from 0 – 40 A up to 0 – 340 A per channel.
3 Independent, fully isolated and bidirectional DC output/input stages, with autoranging.
High speed control interfaces – USB, Ethernet (1 Gbit/s), EtherCAT, CAN FD
