SSR 25DA Solid State Switch Introduction:
- The SSR 25DA is a single phase DC to AC solid state switch. It operates with a control signal of 3-32VDC and a load voltage of 24-480VAC.
- If we apply a DC voltage, such as a 12V DC, to this SSR control part, the solid state relay’s output part will close immediately. It is a Single Pole Single Throw (SPST) switch. It features a very rapid switching speed, requiring only 1ms.
- When paired with a PID temperature controller – assuming it has an SSR output – this solid-state relay can effectively manage heating devices like heating elements, heater tubes, ovens, and so on.
- The solid-state relay is capable of producing a maximum output of 25 amps, so when working with a resistive load, it can power a 2750W heater without issue.
- The back plate of this SSR is galvanized copper material, ensuring excellent heat dissipation performance.
- The inclusion of an internal optocoupler from Fairchild is a critical part of the SSR’s design. While it does increase manufacturing costs, it also significantly enhances the reliability during use.
- Additionally, we can use this SSR 25DA for stage lighting controls, motor starting and stopping, and air conditioning systems.
