SSR 25DA Solid State Switch Introduction:

  • The SSR-25DA is a single phase DC controlled AC solid state relay. Its control voltage is 3-32VDC, and the load voltage range is 24VAC to 480VAC. Maximum load current reaches 25 amps.
  • As we all know, the working principle of solid-state relays is very simple. As long as 3-32VDC voltage is connected to the control terminal, the load part of the circuit will be closed.
  • The load current of 25 amps allows it to run 2000W@220VAC resistive loads such as stainless steel heating elements, incandescent lamps and infrared heating elements without any problem.
  • Thus, the main application of this SSR-25DA SSR is to control the temperature together with the pid temperature controller.
  • Additionally, we can use this 25 amp SSR to control stage lights, motor on/off, ventilation systems, and more. But one thing to note is that when running the motor, the maximum rated power of the motor should be less than 250 watts.
  • Lorentzzi® SSR 25DA solid state relay is produced using world-renowned components. The main component, the optocoupler, comes from Fairchild, ensuring its high reliability and dependability.
  • Another thing to consider is its heat dissipation. This SSR generates too much heat during operation, so an I-50 heat radiator should be used.
