SYCON-66 XX E3 - Automatic Power Factor Controller

Sycon-66XX E3

Certain elctricals loads such as motors found in heavy machinneries ,can cause the electrical system to be highly inductive. this result in poor power factor . poor power factor means higher energy losses which ultimately get converted into large electricity chrges.

A simple solution to this problem is to balance this inductive load with equivalent capacitive load . Tis is achieved by connecting or disconnecting the capacitors to or from the system. Manual switching of these capacitors is not possible in case of rapidly fluctuating loads . So even in an environment of rapidly fluctuating loads to achieve the required power factor one may need an automatic power factor control device, called automatic power factor controller, to connect and disconnect these capacitors.

Sycon 66 XX E3 controller is an automatic power factor controller used to control the power factor of the system . It can sense the powre factor of each individual phase in the three phase system and can switch the capacitors according to the requirement.
