Automatic power factor regulator
1 x 110-240 VAC, 3 x 120-480 VAC, 50-60 Hz Cognito Quam Electrotechnologies Ltd

The PFC1 Power Factor Controller dynamically corrects low inductive power factor lines by switching in and out of the single- or three-phase line compensating capacitors.

The controller detects the load phase angle and drives its three-step output to switch in and out of the line the compensating capacitor banks with response times in the range of 1 to 15 seconds.

This makes the PFC1 particularly suitable for very fast compensation of frequently started, low-duty or variable loads such as:

* lifts,
* conveyors,
* pumps
* fans, and
* office lighting rows.

The controller is fully protected, microprocessor-controlled, very simple to install, versatile and adaptable to all power factor capacitor compensation applications.

The PFC1 controller is designed for standard European and US 50-60 Hz lines. Main features are :

* No neutral connection is required for the three-phase models,
* Phase current detection with a standard 5 A secondary current transformer,
* Dual type galvanically isolated outputs (24 VDC and contact) to directly drive solid state relays (SSRs) and/or higher voltage loads such as contactors,
* External control input to interface to external master devices or thermal protection sensors,
* DIP switch selectable measurement time of 1, 3, 5 and 15 seconds,
* DIP switch selectable initial output state to immediately compensate known loads,
* Simple and intuitive four LED display shows the measured power factor and controller status,
* Comprehensive error detection,
* Current transformer phase error compensation,
* Compensating capacitor time-out protection, and
* DIN rail mountable plastic enclosure.
