The contact variable transformer, we have produced, has no additional distortion and phase shift, high efficiency, high reliability, compact in volume and weight, long life and easy maintenance.
Have wildly be applied to industry as chemical, metallurgical, instrument, machinery, education, research, home appliance, light dimmer, temperature control for variable voltage usage. By moving the carbon brush to change the contact position at the coil, then can continuously change the output voltage.
*High capacity, have no additional distortion, suitable to any type of load.
*Input voltage: Single phase 220V 50/60 Hz, three phase 380V 50/60 Hz
*Output voltage: Single phase 0~250V, three phase 0~450V continuously variable
*Capacity: 500VA ~800KVA.
