M & S Series Power Controllers

Indeeco M & S 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 4 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 2.0 seconds and full off for 2.0 seconds. Line voltage is used to power the electronics. An external transformer is not required. 

Features

  • Proportional Control - Output is controllable from 0-100% of rated load.

  • Input Flexibility - Models are available with all standard ohmic, voltage, and milliamp inputs.

  • Packaged Units - Control and power units are packaged and pre-wired to reduce field labor costs.

  • High Ambient Rating - The units are rated to to 186°F ambient.

  • Built-in Transformer - Built-in transformer eliminates the need to wire the control board to a low voltage circuit.

  • Fail Safe Circuitry - Output is off if input leads are shorted or opened, except with contact closure option.

  • Isolated Heat Sink - Heat Sink is electrically isolated from line voltage.

  • Function Indicator - An LED indicator allows easy monitoring of system operation.

  • Transient Absorbers - All units are equipped with transient/surge absorbers (MOV's).

  • Optical Isolation - Control circuit is optically isolated from the power circuit providing additional ground fault protection.

  • Vernier Control - Slave units can be used with Indeeco sequencers to obtain full vernier control.

  • Digital Display - All SCR's can be used with RTD input providing digital display of the temperature.  Eliminates the need for a separate temperature controller.
