Description

The self-powered AC solid state relay with MOSFETs reference design is a single relay replacement that enables efficient power management for a low-power alternative to standard electromechanical relays in thermostat applications. This SSR reference design is self-powered through the 24V AC power line, eliminating additional power consumption of thermostat battery. The MOSFETs can switch fast enough to allow self-charging without affecting the load.

Features
  • No clicking sound
  • Cost efficient BOM
  • MOSFET-based design for fast on/off switching
  • Zero thermostat battery power consumption
  • Under-voltage and over-current protection
