DC Ground Power Unit

Introduction

GSY-PS-CW DC Ground Power Unit is specially designed to give continuous high quality DC power. This continuous high power model is ideal for crew training, aircraft servicing in workshops, on the ramp or in the field, diagnostic work, preflight checks, charging the on board battery or for continuous powering of equipment during operations, without draining the onboard aircraft batteries.

The safety features include over voltage, overload and internal thermal, short circuit protection. The power modules conform to EMC standards for noise emissions and immunity.
