Our power factor controls dynamically monitor and minimize the reactive and apparent power currents in the monitored installation and so maximize current capacity utilization as well as minimize overall conduction losses. Their response time makes them suitable for effective compensation of frequently started, low-duty or variable loads such as lifts, conveyors, pumps, production machinery, fans and office lighting.

 

The AVSR3 triple switch autocalibrating variable step power factor regulator employs our variable step technology to compensate reactive current in seven steps. It features three 25 A solid state switches to connect three autodetected compensating capacitors in and out of the single- or three- phase line system. AVSR3 installation is purely "wire-up-and-play" as all operation parameters are autodetected and no adjustments are required.

The VSPFC variable step power factor controller provides for different capacitor banks of any size to correct power factor in practically any arbitary minimum step and correction range size.

The PFC1 fast power factor controller detects the load phase angle and drives its three-step output to switch in and out of the line compensating capacitor banks with response times in the range of 1 to 15 seconds.

RCCS1 Single power factor reactive current controlled switch The RCCS1 and RCCS3 power factor reactive current controlled switches address simpler, fixed load power factor compensation applications and incorporate the capacitor switching SSRs. RCCS3 Triple power factor reactive current controlled switch

RCC3 Three phase reactive current power factor control PFCD1R Power factor current detector The RCCx reactive current power factor control closes a set of output contacts when the monitored reactive current is above the set limit. The PFCDxx power factor current detector detects the apparent power and one of the reactive or active power currents to generate two related analog outputs for further processing by external devices such as a PLC.

The CACSW integrated power factor capacitor AC switch connects a single- or three-phase 25 A power factor capacitor bank to the line, employing bypassed, zero crossing, solid state thyristor switches.

Assembled, ready-to-install power factor correction systems in wall mountable cabinets are available on a custom basis.
