About this item

  • FAST SWITCHING: Solid State Relay SSR-25AA is an electronic switching device that switches electrical loads on and off without mechanical contact. Solid state relay has no moving parts to wear out and is able to switch both “ON” and “OFF” much faster than mechanical relays. It also offers high isolation between the control circuit and the load circuit, enhancing safety and protecting control circuitry from high-voltage load circuits
  • PERFECT FIT: Solid State Relay SSR-25AA is perfect for a range of applications in household and industrial automation, including temperature control, heating and cooling systems, computer numerical control (CNC) machinery, remote control setups, and more. It fits SSR with the same specification: AC to AC Input 80-250VAC to Output 24-380VAC 25A, Insulation Resistance: 1000M Ohm/500VDC, Ambient Temperature: ~30~+70℃, Off Leakage Current: ≤5mA
  • HIGH-PERFORMANCE OPTOCOUPLER: SSR-25AA Solid State Relay is equipped with a heat-dissipating metal back plate and a copper terminal lug for superior conductivity. BlueStars ensures longevity with a high-quality semiconductor optocoupler, along with spark-proof, noiseless operation via chemical contact-free action and zero cross-trigger control. Especially, this part is suitable for corrosion, moisture, dust resistant and other harsh environments.
  • FAIRLY EASY INSTALLATION: Experience hassle-free installation with our user-friendly Solid State Relay SSR-25AA. Save time and effort without compromising on quality - our product is crafted to seamlessly integrate into your setup with minimal fuss
  • 100% LIFETIME PROTECTION: Enjoy reliable performance with our lifetime protection, ensuring that your product will always be covered for any defects or issues that may arise.

I use them with a pid controller and a hotplate for doing chemical distillations and they've been rock solid. Mind you, I don't have them cycling like a mosfet either and keep the hysteresis mild but they do run at around 4-7Hz without getting warm at all. Overall I really can't complain, especially for the price.

I have several of these specific ssr units. two have leterally caught on fire. the first one could have been my fault relative to the torque on the terminal screws but this most recent unit had a short circuit on the output side that was protected by a 3 amp circuit breaker. the breaker triped as it should have but the cube exploded and caught on fire right after tripping the 30a main breaker feeding the circuit.very unstable circuitry.buyer beware.

Output would connect after input energized on 120v. Output stayed connected on both after input was disconnected/de-energized.
