Microdry Inc., has a limited number of reconditioned 75kW microwave transmitters with Poly-Phase Transformers and six phase rectifiers. The poly-phase transformer and the six-phase rectification give this microwave power transmitter a more stable operation with a longer magnetron life. With the combination of a high impedance transformer and krypton spark gap, the unavoidable arc-off of a high power transmitter is less violent ... almost undetectable. These transmitters are controlled by an Allen-Bradley SLC 5/03 PLC that can be upgraded with an optional 550 panel view (shown). For magnetron protection, it has an external three-port circulator to prevent damage during high reflected power periods. A directional coupler monitors the reflected power and deenergizes the high voltage to the magnetron should the reflected power level increase above a preset level.
