RPS428400

RPS428400 is a 4kW isolated auxiliary power supply designed for aerospace prototyping applications.  This unit offers 18 controllable output channels.  Each channel can be independently set for an output voltage of 11 to 28V and a software fuse current of 0 to 20A.  Each channel has an analog hardware current limiter of 40A with pulse-mode current testing to support a variety of inrush currents and short-circuit scenarios.  There is a software blocking time that prevents the software fuse to operate too fast during normal inrush scenarios.  Channels share the same ground but are isolated from the input 400V dc bus.  Input range supports 300 – 450V.  Other input ratings can be ordered via customization.
