Frequently Asked Questions

Q: What is the difference between the SSR-10VA, SSR-25VA, SSR-40VA, and SSR-100VA models?

A: The models differ in their maximum load current ratings — 10A, 25A, 40A, and 100A respectively. All models share the same 24–380VAC output range and DC control input. Choose the model rated at or above your application's maximum load current for safe, reliable operation.

Q: What control voltage do I need to trigger these solid state relays?

A: These SSRs accept a DC control voltage of 5–250VDC, making them compatible with a wide range of controllers including PLCs, Arduino/microcontrollers, and standard DC power supplies.

Q: Are these solid state relays suitable for outdoor or harsh environments?

A: Yes. The epoxy-encapsulated housing provides excellent resistance to corrosion, moisture, and dust. They also operate across a wide temperature range of -30°C to +70°C, making them well-suited for challenging industrial and outdoor environments.

Q: Do these SSRs require a heat sink?

A: For higher current models (40A and above) operating near maximum load, attaching an appropriate heat sink is recommended to maintain optimal performance and extend the relay's service life. Lower-current models used within their rated limits typically generate less heat.
