SSR 40VA Solid State Voltage Regulator Introduction:

  • The Lorentzzi SSR-40VA is a potentiometer manually controlled 40 amp AC solid state voltage regulator (SSVR). The SSVR uses phase angle control (phase shedding) to regulate the output voltage.
  • Its control signal is a 220-440k ohm potentiometer, load voltage range is 0-380VAC. With the potentiometer resistance increasing or decreasing, the load voltage will decrease or increase reversely. Its curve is like followed picture:

  • Since the SSR-40VA has a maximum current draw of 40 amps. So, by calculation, it can easily run a heater or other resistive load up to 4kW at 220VAC.
  • Compared with the single phase Solid State Relay(SSR), SSVR has the advantages of precise control and manually adjustable voltage.
  • Easy panel mounting method makes it very easy to install in the distribution box with other components such as MCB, timer, contactor etc.
  • The application for this solid state voltage regulator includes heaters, light dimming control, oven temperature control with the temperature controller and so on.
