The VSPFC variable step controller provides for different capacitor banks of any size to correct power factor in practically any arbitary minimum step and correction range size. At every sampling instant, the controller calculates the required compensation step and connects or disconnects a combination of banks whose sum is equal or closest to the calculated step value. As an example, four banks sized as x5, x2, x2 and x1 multiples of the smallest required step provide a decade of compensating operation and function as a typical ten equal step system. The maximum correction range possible with the VSPFC is when all its 12 outputs are employed in a binary weighted system (x1, x2, x4, x8 .. x2048) and equal to 4095 steps.

  The controller has been designed for power factor control applications with the following features and characteristics:

The VSPFC operates in regulating or compensating mode. In regulator mode the current is detected at the line side and equals to the sum of the load and connected capacitor currents. In this mode the Controller switches capacitor banks in and out of the line to minimize reactive current at the line side. In compensator mode the current is detected at the load side and is equal only to the load current. In this mode the Controller switches the banks in and out of the line to compensate the detected reactive load current as closely as feasible by the available bank sizes.

The VSPFC is offered with accompanying setup and monitoring PC software.

Our CACSW integrated PF capacitor AC switch interfaces directly to each VSPFC bit I/O pair in switching and monitoring capacitor banks up to 3x25 A. Other power factor related products are summarized here with sampling/small quantities being available for online purchase here.

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