-
Temperature Protection: Internal sensor measures heat every 100ms, switching off outputs if unsafe levels are detected
-
Overpower Protection: Automatically disconnects load and sends notification if power exceeds safe thresholds
-
Overvoltage Protection: Detects voltage peaks and switches off to protect connected appliances
-
Improved Thermal Performance: 4-layer PCBs for better heat dissipation
Smart Home & Commercial Applications
Perfect for homes, offices, retail stores, restaurants, and manufacturing facilities. Automate lighting systems, HVAC units, water heaters, commercial kitchen equipment, and more. The Pro 1PM works with existing wall switches and requires no additional wiring beyond standard DIN rail installation.
