Bidirectional DC source/sink with energy recovery » LAB/HPR



Compact bidirectional DC source/sink

LAB/HPR DC sources are 19" voltage sources with bidirectional power from 7 kW to 1.4 MW. They can function both as a load and as a power supply unit, thus enabling energy-efficient recovery by feeding energy back into the grid. As a developer and manufacturer, we also offer customised solutions in addition to our standard devices.

Standard interfaces:HMI, Ethernet LAN, Analog 5/10V, RS232
Optional interfaces:IEEE 488, RS485, USB
