Single Phase Solid State Relays (for capacitor purpose 530V)
GDF Compound SSR
Series GDF Compound Solid State Relay is a new type relay product developed independently according to demand of the user. It is a singular module that is comprised by a SSR that has zero tune on-off function connects the load at first an disconnects loads at last and a mechanical relay that has low power waste keeps connection of load at other working time.
GDF avoids the disadvantages that mechanical relay make the surge current when it turns on and make arc when it turns off with SSR or thyristor switch will make power waste heat from the voltage drop of silicon during it is on work.
GDF can be widely used in the power capacitor turning on and off, motor switching on off and temperature controlling of industry furnace etc.
Feature
·Bar structure, convenient for mounting and using.
