GVDA series single phase AC switching module
| This product is a multi-functional power module, which integrates thyristor power circuit, SCM-control phase-shift trigger circuit, signals detects and transfer circuit, voltage modulation circuit. It can realize the precise control of the voltage of the load. With built-in linear control circuit, it is highly precise and stabilized. Rated current: 50-500A, rated voltage: 220V, 380V, 440V, 50Hz or 60Hz. It is widely used in all kinds of induction and impedance loads, for instance: AC motor, transformer, temperature control, light change, AC voltage modulation. |
