This is the Pre-Production, Transformer and Inverter Assembly from the NCS1 Space Reference Unit [SRU]. It contains inverter units made by Rotron.
Both Rotron Inverters are fed from 28VDC. The small inverter [designated BATAC (NI) model BC330] supplies the SRU gimbal fan at a constant speed. The much larger inverter [designated BATA (N2) model BC139] is supplies the SRU (overheat) exhaust fan.
The front panel of this unit is quite plain and is secured to the SRU in by six captive screws (most missing from this unit).
