Introduction:
- Our SSR-40DA is the most popular and commonly used DC to AC solid state relay with load current up to 40 amps, which can handle most loads on the market.
- Its control voltage is DC3-32V and the load voltage range is AC24-480V, that is, once the control voltage is applied, the load part of the circuit will be closed. This feature makes it widely used in temperature control systems with a PID temperature controller.
- Since the SSR-40DA has a maximum current of 40 amps, it can operate 220VAC heating elements up to 4000 watts. If that’s not enough, you can try our SSR-60DA (for heaters up to 6000W), SSR-80DA (for heaters up to 8000W), or SSR-100DA (for heaters up to 10kW).
- Our SSR-40DA solid state relay has random turn on and zero-crossing control modes to choose from. Random turn on SSR is faster, while zero-crossing SSR has lower electronic noise.
- Same as the contactor, the solid state relay is a switch which uses a low voltage to control a high voltage, but the solid state relay has more advantages, such as fast responding time, no noise, long lifetime etc, for more information, read our article: SSR Vs. AC Contactor: Which Is Better In A Temperature Control System?
- Our SSR-40DA SSR price is under USD10.0, this does not mean low quality, as we sell directly without a middle man, and we can provide 2 years warranty.
