SSR-25DD Solid State Relay
Key Features
- Control Method: DC to DC (DC Input, DC Output)
- Input Control Voltage: 3-32V DC
- Output Load Voltage: 5-200V DC
- Maximum Load Current: 25A
- Response Time: ≤10ms
- Dielectric Strength: >2.5KV
- Design: No moving parts for silent operation and extended lifespan. Features an isolated baseplate for efficient heat dissipation.
Replaces / Cross-Reference Part Numbers
- SSR-25DD
Compatibility & Fitment
- Suitable for switching high-current DC loads using a low-voltage DC control signal.
- Common applications include industrial automation, CNC machinery, DC motor control, DC heating elements, and robotics.
- Compatible with output signals from microcontrollers such as Arduino, Raspberry Pi, and other PLC systems.
When to Replace
- The relay fails to activate the load when a control signal is present.
- The load remains permanently on, even without a control signal.
- Switching becomes intermittent or unreliable.
- The relay overheats excessively during operation, indicating internal failure.
- Visible physical damage, such as cracks, burns, or melted housing.
Installation Tips
- Disconnect all power sources before installation or service.
- A heat sink is required for load currents exceeding 10A to ensure proper thermal management and prevent overheating.
- Apply a thin layer of thermal paste between the relay's metal base and the heat sink for optimal heat transfer.
- Ensure all wire connections are secure to prevent poor contact and potential arcing.
- Verify correct polarity for both the DC input (control) and DC output (load) terminals.

Soft and cool. Very cool. 🧊
Size: Queen, Color: White
I bought these for my memory foam pillow and they’re excellent for cooling it. I use 2 of these on the pillow for maximum chill factor and it works.
They’re very soft, the zippers are high quality. Easy to put on with a bit of stretch- generously sized. They’re stain resistant. I’m glad they’re NOT waterproof because they’d be too hot then. They’re very durable. Wash on delicate setting in a mesh bag and air dry and they last long. They’re very quiet- smooth and silky. Definitely recommend!

Cool enough
Size: Queen, Color: White, Size: Queen, Color: White
I thought I had purchased pillows so when I received these I was a little disappointed. However that was 100% on me for not reading the listing and just trusting my search. I decided to give them a try and so far they seem ok. They don’t stay cool even though I have them on cooling pillows. They are super thin but very soft. They fit on my pillows perfectly. I don’t think it has improved my sleep quality but it hasn’t made it any worse either. I don’t think they are waterproof but I don’t really want to test that. I like that the zipper is small and seems to be decent quality. Smelled heavily of chemicals when I first took it out of the package but that disappeared after a few minutes.

Great pillow!
Size: Queen (Pack of 2)
They were a gift for my daughter and she loves them! She says they are comfortable and "squishy" and she sleeps better on them.
