The GR 850 is a singlephase, «hot-pluggable», fan-cooled rectifier. With its exceptional power density (30 W / in³) it offers optimal solutions for the 1 U‘ shelf DC ST801 and the 2 U’ shelf DC ST802 in the power range from 850W up to 5100W.
The small installation depth and the large temperature range are further advantages of this modern rectifier. The high efficiency (up to 95, 2%) guarantees an energy-saving operation. In addition less cooling energy is needed. Due to the temperature- independent fan control, a low noise level is achieved.
