DC Solid State Relay SSR 10A 25A 40A Single Phase White Shell
DC Solid State Relay SSR 10A 25A 40A Single Phase White Shell
DC to DC Single Phase Solid State Relay – SSR 10A / 25A / 40A
The CKCTINNER SSR series single-phase solid state relay is a high-performance, contactless switching solution engineered for demanding industrial and automation environments. With a durable white shell and CE-certified construction, it replaces traditional electromechanical relays in digital program-controlled devices, temperature control systems, data processing setups, and computer terminal interface circuits — all with greater reliability and longer service life.
Designed to withstand high-corrosion, high-humidity, and frequent-switching conditions, this solid state relay eliminates mechanical wear for virtually silent, arc-free operation. Available in 10A, 25A, and 40A load current variants to suit a wide range of applications.

Frequently Asked Questions
Q: What is the difference between the SSR-10DD, SSR-25DD, and SSR-40DD solid state relay variants?
A: The three variants differ in their maximum load current rating: SSR-10DD handles up to 10A, SSR-25DD up to 25A, and SSR-40DD up to 40A. All share the same DC control input (5–60V DC) and DC output (3–32V DC) range. Choose based on the current draw of the load circuit you intend to switch.
Q: Can this solid state relay be used in wet or corrosive environments?
A: Yes. The CKCTINNER SSR is specifically designed for harsh environments including high-humidity, wet ash, and high-corrosion applications. Its robust white shell housing and contactless operation make it well-suited for demanding industrial settings where electromechanical relays would deteriorate quickly.
Q: How do I know when the relay is active?
A: The relay features a built-in LED work indicator that illuminates when the relay is switched on, providing immediate visual confirmation of the relay's operating status — making installation checks and troubleshooting straightforward.
Q: Is this relay compatible with PLC and microcontroller outputs?
A: Yes. With a low control current requirement of just 3–25mA DC and a wide control voltage range of 5–60V DC, this SSR is fully compatible with most PLC output modules, Arduino, Raspberry Pi, and other microcontroller-based systems.
