Key Features:

  • Active PFC (Power Factor Correction): ≥ 0.99 at full load
  • Parallel operation capable (up to 4 units with current sharing)
  • Remote ON/OFF control via dry contact input
  • LED indicators: Power (green), Fault (red), Output OK (green)

Applicable Industries: PLC/HMI power supply, CNC machine control, robotics, industrial PCs, LED lighting systems, security systems

Installation Requirements:

  • Mount vertically with fan facing up for optimal airflow
  • Leave minimum 50 mm clearance above and below for ventilation
  • Input fuse required: 6 A slow-blow (T6A) at 230 V AC
  • Output cable: minimum 4 mm² copper for 12.5 A continuous current

Usage Notes:

  • Derate output current by 3.5% per °C above 50°C ambient
  • Do not block fan intake or exhaust — causes thermal shutdown
  • Parallel operation requires external current-sharing modules (sold separately)
  • Perform output voltage trim at commissioning to exact required value
