EA PSB 20000 Triple — three-channel bidirectional power supply 15/30 kW
Country: Germany · Model: PSB 20000 Triple
PSB 20000 Triple has three galvanically isolated bidirectional channels, 15 kW in total in a 3U housing or 30 kW in 4U. The voltage of each channel reaches 920 V, and energy from load mode returns to the grid with an efficiency of up to 96,5 %. The device combines parallel tests of motors, inverters and onboard chargers in one setup.

Description
The channels are independent of each other, so one can simulate a traction battery while the other two power auxiliary circuits or load the output of a charger. The 3U model splits 15 kW into 3 × 5 kW with a current of up to 170 A per channel, the 4U model gives 3 × 10 kW and up to 340 A. The channel voltage, depending on the version, is from 0–60 V to 0–920 V. The supply is three-phase, 208–480 V ±10 %. For integration into a bench there are USB, Ethernet 1 Gbit/s, EtherCAT and CAN FD with a data exchange speed of 1 ms, which matters when synchronizing with a motor control system. Water cooling is available as an option. One housing instead of three separate supplies saves rack space and simplifies cabling.
How to choose
The current per channel decides, since the 3U is limited to 170 A while the 4U gives 340 A. If one channel is enough but a voltage up to 2000 V is needed, consider PSB 10000 at 1,5–30 kW. For industrial benches at 30 and 60 kW per unit there is PUB 10000, and cabinets up to 300 kW per rack are supplied as High Power DC Racks.
