Power Factor Controllers

Power Factor Controllers  

The ESTAmat MH/PFC can be employed wherever manual and automatic control of central power factor correction equipment in low and medium voltage plants is required. It is a Power Factor Controller based on both longstanding know-how in the field of reactive current control technique and the latest developments in micro-electronics. All functions of the ESTAmat MH/PFC are controlled by a microprocessor.

Applications
