Turns an inexpensive Solid State Relay into a low cost SCR Power Control

The microprocessor based SSRMAN-1P phase angle control module is designed for use in a broad range of power control applications using a solid state relay.  The SSRMAN-1P mounts directly on the input terminals of an SSR and converts it into a low cost phase angle controller by providing true linear power control of the load via the SSR's logic input.  Using the SSRMAN-1P with the appropriate SSR for your load will provide a modular feature packed high isolation SCR power control at a very low price.  

The SSRMAN-1P's output power is proportional to the command input which can be selected from eight different industry standard inputs.    User configurable features such as Soft Start, Line Voltage Compensation and Voltage Limit make the SSRMAN-1P a perfect fit for any phase angle power control application.  Soft start is especially useful on high inrush loads such as Quartz, Molybdenum, Tungsten, or Graphite heaters.  The SSRMAN-1P's Line Voltage Compensation forces the output power to track changes in line voltage and acts as an efficient feedforward control mechanism which will make any process more stable.  Soft Start and Line Voltage Compensation can be set on or off using the configuration dipswitch.  Voltage Limit is set via a potentiometer and will limit the voltage on your load by limiting the maximum phase angle allowed on the output.  The SSRMAN-1P phase angle control module must be used with non-zero crossing, random fire solid state relays.  The SSRMAN-1P will not operate properly with zero cross fired solid state relays.
