Request Pricing
Description
The AVD800 is an industrial-grade AC power voltage detector designed to monitor 8 loops of 140~240VAC 50Hz power voltage status. It outputs dry contact signals to alert users of voltage loss, ensuring high reliability, low power consumption, and precision. Its fire-retardant shell and DIN rail mounting make it suitable for harsh environments.



Key Features
  • Monitors 8 loops of AC power voltage (140~240VAC 50Hz).
  • Dry contact output (NC/NO) for alarm signaling.
  • No external power supply required for basic operation.
  • High insulation resistance (>1000V) between input and output.
  • Compact design with 35mm DIN rail mounting.
  • Fire-retardant housing for industrial safety.

Typical Application Scenarios
  • Base Transceiver Station (BTS) power monitoring.
  • Diesel generator rooms and engine rooms.
  • Transformer substations and telecommunication equipment rooms.
  • Power supply system backups and critical infrastructure.
