1PWA Series Solid State Power Controller

1PWA is a single-channel high-power SSPC series solid-state power controller with a load voltage of 28Vd.c.~270Vd.c., and a load current of 10A~100A.

Controller featured functions:

Field bus function to control relay on and off. The controller can also be switched manually during emergency
Load current detection, overcurrent protection and short circuit trip function

It is suitable for the field of defense, and can be used in the control system of tanks, aircraft, ships and ground equipment.

Note 1: This table includes the range of time covered by 8 over-current trip protection curves for solid-state power controllers. The over-current trip time of solid-state power controller will be determined by 5# curve if not specified, Note 2: The protection maintenance delay time of the solid-state power controller is a continuous function of the current, which is a collection of countless “points”. The 5 tested points specified in the above table are included in the ” Overcurrent protection curve”, rather than all the information about the overcurrent protection characteristic.
