45 amp dc power system

Product Information

Aspiro 1U is a compact 1RU high 19/23” or ETSI rack-mounted, integrated 45 Amp DC power system providing an output of -48VDC.

The Aspiro 1U 45 amp DC power system can accommodate 1 or 2 Aspiro family high efficiency hotswap rectifiers. A total load + charge current of 45A / 2.4kW is available. The rectifiers are internally fan cooled with speed control which is a function of load and temperature, keeping acoustic noise to a minimum.

The DC output circuits can provide up to 4 loads with breakers rated from 1A to 30A. An additional breaker provides battery protection. A programmable low voltage battery disconnect (LVD) is standard.
