Phase Angle Control Power Supplies

MSI Phase Angle Control Power Supply
The phase angle control (AC) power supplies use a pair of anti-parallel silicon controlled rectifiers to vary the power output of the power supply.  In most cases the SCRs are transformer coupled to the load.


  • Output command via 4-20mA, 1-5V, or other custom range
  • Current limiting available for loads that have low resistance at start up
  • NEMA 1 or 3R Enclosure
