BlueStars Pack of 2 SSR-25DD Solid State Relay DC 3–32V Input, DC 5–200V Output, 25A Single Phase

FAST SWITCHING: Solid State Relay SSR-25DD 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 SSR-25DD 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: DC to DC Input 3-32VDC to Output 5-200V 25A, Insulation Resistance: 500M Ohm/500VDC, Ambient Temperature: ~30~+70℃, Off Leakage Current: ≤5mA
HIGH-PERFORMANCE OPTOCOUPLER: SSR-25DD 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-25DD. 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.
