8 Steps APFC Relay 240V 63PFC

8 Steps APFC Relay 240V 63PFC is used, where the power factor load fluctuates greatly with variation. It check as shown above measurement of the power factor with set desired power factor and if it less than it gives the command to switch one step capacitor unit to get the desired set of power factor.

If examined power factor is more than set value of power factor, then it gives the command to switch off connected capacitor steps until unless it reaches the desired set of power factor value.

In the panel, capacitors are connecting and disconnect automatically with the help of automatic power factor correction relay.

APFC Relay use to automate capacitor bank and one of the most difficult roles in place where high and controlled amount of electricity is applicable.

This includes large factories or industries or schools or colleges.

APFC Relay is especially necessary for colleges; because students are learn on the basis of the various types of voltage and ampere fluctuations in practical labs.

However, all relays cannot be too accurate and therefore, there is a need of a very accurate and precise control relay.

Easy Installation of 8 Steps APFC Relay 240V 63PFC :

This APFC power factor control relay is very easy to install and does not in any way prove difficult to understand. Further, it is also small in size which only facilitates the ease of installation.

Intelligent Capacitor Status Indicator:

The intelligent capacitor status indicator of this power factor controller with display is one innovative idea. It indicates how many capacitors are switch on or off, thus adding an exclusive feature to the device.

Long Life (8 Steps APFC Relay 240V 63PFC)

The Celec display power factor controller has a very long life because of the durable materials used to manufacture it as well as the device is also lightweight.


Controller provides sign and control to contactors to reach unity power factor capacitor taking care of discharge time and switching control APFC relay is the main control device in automatic capacitor banks designed to run 24 hour continue.
