4U 48VDC 15kW DC Power System with Distribution

Switching Mode Rectifier (SMR) system provides uninterruptible and reliable DC power to wide variety of devices which require high quality DC source. With its high efficiency and compact size, RA-3048 rectifier module saves energy and space for system installers, which means more flexibility and less OPEX..

Multiple rectifiers can be configured by central control unit CE-R1 , which makes sure identical parameters setting and load sharing. Meanwhile, charging parameters monitoring and setting are completely considered in CE-R1, to make sure battery charging condition is optimized. In our DC power system, protection mechanisms such as Input voltage protection and temperature protection are included. Hardware protection such as circuit breaker , SPD (Surge Protection Device- available with M system or above) and Low voltage Disconnect (LVDS) with battery can protect system further when necessary.

A complete DC power system is consisted of below elements in terms of function blocks:
