$333.01
Progressive Dynamics PD52 is a 240 VAC, 50 Amp transfer relay. This automatic transfer switch has a 30 second selectable delay with quick-connect terminals for easy installation.
A transfer switch can be used to automatically switch between inverter power and a generator. The PD52 automatically senses generator power and prevents two power sources from entering the AC distribution panel at the same time.
Description of Operation
- When power is applied to the shore side, the contactor activates and supplies power to the panel.
- When power is applied to the Gen side there is a 20-45 second delay then the Gen side contact will activate, power will go to the panel from the Gen side and the shore side will be locked out, GREEN generator LED on the circuit boardl will light.
- If shore power returns while the Gen power is present, nothing will happen. When the Gen power is removed the contactor will drop out and allow the shore side to supply power.
- In a single leg application, the HOT1 side must be used for the control circuitry to work.
