  4-20mA Phase Angle (Back to Back SCR )
 
# 707 Model
weight : @110 gms. 		Circuit Diagram Performance Graph


 
  Precaution
 
  • Used for resistive/inductive transformer load only
  • Do not give DC Voltage at 4-20mA input control of
    SSR otherwise input of SSR will fail.
  • Phase Line voltageshould be in range of 230 VAC
    +10 % or 440 vac+10 %
  • SSR will not work if heater connnected in star
    without neutral.
  • Heat sink temperatures should not increase700C
  • For dv/dt and transient voltage uses dv/dt
    snubber and metal
 
  Pot Used For
 
  • Line Voltage variation
  • Balancing voltage in each phase at fixed
 
  Application
 
  • Glass industries/Furnace industries
  • Paper industries
  • Hot runner system of plastic Processing Machinery
  • Polyester yarn Processing industries
  • The load power is Proportional to controller input
  • Output to body 4kV isolation
  • Heat Sink + Din Rail Mounting (35mm)
