DKP series rectifier control equipment is a traditional product produced by our company. It adopts three wire two-phase half wave rectifier with fixed output voltage. DKP-A series products are improved on the basis of DKP series. When the grid voltage is low, the output voltage can be adjusted in the range of 170-240 V by adjusting the potentiometer and changing the thyristor conduction angle, so that the output voltage is basically close to 220 v. It is suitable for electromagnet with output current below 122a.
