Sensata | Crydom Solid-State Relay, 20ms Turn-On Time, 30ms Turn-Off Time - HA Series - HA4825

Need a reliable control solution for your circuit? Switch to this solid-state relay from Sensata | Crydom. It converts an input electrical signal into an optical one for an internal transistor that sends power to the circuit. This means it doesn't have any moving parts, so there's no risk of mechanical wear. The unit's housing features anti-rotation barriers that help lend a steady handy to keep it stable on shaky ground. You can use this SSR to switch medical devices on and off.

Features & Benefits

• Maximum turn-on time of 20ms and turn-off time of 30ms for rapid switching

• Tough aluminium baseplate resists impact and corrosion

• Integrated mounting holes for convenient panel mounting

Can I use this SSR with high-current devices?

Yes, this SSR has a rated load current of 25A, so it's a safe bet for use in high-power systems.

How durable is this SSR?

Thanks to its MTBF of more than 11 million hours at +40°C and over seven million hours at +60°C, you can use this SSR for the long haul.
