A Series and B Series Power Controllers

A Series and B Series power controllers are solid state, zero-cross fired, proportional devices. Line voltage is switched 0 - 100% linearly, with respect to the input range. A 1 second time-base controls power to the load.  For example, a 5VDC signal to a 0 -10VDC input will cycle the output full on for 0.5 seconds and full off for 0.5 seconds.

Features of these controls include an LED to indicate when the output should be on.  Also, the output will be shut off if the input signal is disconnected or shorted.

Masters can operate alone or can drive additional slaves to control multiple loads.  Other VDC type controls can drive slaves.

Series A Power Controllers (Master)

  • Zero-cross fired solid-state relays, proportional control

  • 4 field-selectable inputs; 2200 ohm, 135 ohm, 4-20mA, 0-10VDC
