A Series and B Series Power Controllers (Series 101, 102, 103, & 108 )

Available as Model A (master) and Model B (slave), Indeeco 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.

Standard Features

Notable features of these controls include an LED to indicate when the output is on and for safety purposes if the input signal is disconnected or shorted the output will be de-energized.

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

Short Circuit Current Ratings (SCCR) up to 100KA available, well above the default 5KA value for typical SCR power controllers.
