• Humidity: up to 50% at 40 °C; up to 90% in the most humid month at ≤25 °C

Functions

Automatic power source selection: When a phase loss, overvoltage or undervoltage is detected in the main supply, the load is switched to the backup source.
Generator control: The controller automatically issues start/stop commands to the generator.
Three operating modes:
• Automatic switching and automatic return to main power.
• Automatic switching without return – return only manually.
• Power sharing – main power is used until the backup supply becomes unstable.
• Dual logic: Electronic + electrical protection for reliable operation.
• Interference protection: Resistant to strong electromagnetic disturbances.
• Independent input/output: Works with or without automatic control commands.

Usage

For home users: Ensures automatic generator start during power outages. Suitable for houses, cottages, garages or farms requiring reliable backup power.
For engineers: Enables precise control of two power sources, monitoring voltage and modes. Compact design fits switchboards. RS485 interface allows automation system integration.
For electricians: Suitable for professional backup solutions (generators, UPS, transformer stations). Easy to install in control panels. Clear LCD simplifies diagnostics.
