SSR 25AA AC AC Solid State Relay Introduction:
- Lorentzzi SSR-25AA is a AC controlled AC solid state relay, control voltage is 70-280VAC, its load voltage is 24-480VAC. The low voltage part and high voltage part is isolated by an optocoupler. Once the low voltage part circuit is closed, the high voltage circuit will be closed as well
- Compared with the SSR-40AA solid state relay, this SSR-25AA product has a load current as low as 25A, which is very economical for small heaters not exceeding 2700W.
- The AC solid state relay housing is made of flame retardant material, making it safe to use in long-term and high-temperature environments.
- The base plate is made of copper to ensure good heat dissipation performance.
- Built-in RC absorption circuit to reduce noise when heavy load is turned on.
- Our SSR-25AA 25A solid state relay optocoupler is purchased from Fairchild (Infineon), giving it good stability and reliability.
- One thing to note is that when using this solid state relay, a suitable heat sink should be used, such as our I-50 Heat Sink.
