Introduction:
- Lorentzzi® SSR-25VA is a manually controlled solid-state voltage regulator, controlled by a resistor potentiometer. By increasing or decreasing the potentiometer resistance, the voltage will increase or decrease accordingly.
- The control part is a 220-560 KΩ potentiometer, and the load voltage is 24 to 380 VAC. As mentioned above, the load voltage will increase linearly from 24 to the applied voltage. Or vice versa.
- The SSR-25VA adjusts its output power through adjusting the output voltage.
- Its maximum load current of 25 amps makes it suitable for a variety of applications, especially resistive loads such as heaters, heating lamps, and even some motors. Note that if the load is a heater, its power should be less than 3000 watts @ 220 VAC.
- The wiring diagram of this potentiometer control solid state voltage regulator is as following:
- Application of potentiometer control SSVR: Heater precise temperature control, incandescent lamp brightness adjustment, some types of motor speed control etc.
