Product Questions & OEM Opportunities:

Application Example :
Switch for Battery Management Systems

High-side switching in a BMS is a difficult problem to solve - requiring speciality chips and charge-pumps.

This is a dream device if you want to design your own BMS - this SSR completely disengages the power path with a signal from the micro-processor in the BMS.

Minimal Power Loss because it is not a SCR or IGBT device - it is made from Mosfets.

Application Example :
Remote Switch for DC Motors

Your Motor line is completely isolated from the "logic line". You don't have to worry about electrical noise from motor disturbing your sensitive controller electronics.

Application Example :
PID/PWM Control of Heater

If your application requires a huge amount of on/off cycling - such as PID control with PWM, then mechanical relays will burn out fast. This type of SSR is a good solution.
