Highly efficient power supply and backup power supply solutions to telecommunications, information and industrial technologies.

BNH2-2 Power Supply



The BNH2-2 power and backup supply is designed for usage with industrial, control, telecom and security technologies. This compact 19“ rack solution allows for a connection of up to two DPR1200B – 48 rectifiers and an intelligent controller module. BNH2-2 is available in a version with one rectifier (no redundancy) or in a version with two rectifiers (1 1 rectifier redundancy). Both versions have the same power characteristics of 1200W.

BNH2-2 allows for a connection of up to 2 battery sets; the load can be connected to a maximum of 2 outputs. Batteries can be placed as stand-alone or kept with the power supply (depending on the size of the cabinet). The front panel contains an LCD display with buttons and a USB port (for service use only). Ships already assembled.
