This is a Power Supply for running the Gyros during testing of NCS1 The unit operates from mains power (230Vac or 115Vac) to permit bench testing away from the ship’s power supplies. The Power Supply can drive the NCS1 Gyros or an alternative called Arma-Brown Gyros. Currently we do not know why this other Gyro is included.
(From about 1950 to 1964 the American Bosch Arma Corporation developed a two-degree-of-freedom flotation gyroscope which was generally used as a precision displacement gyroscope. This gyro has the unusual, if not unique, feature that it is a floating two-degree-of-freedom gyro supported at neutral buoyancy free of mechanical gimbal pivots or ball-bearings.)
