Product features

  • Max and BIAS adjustments are independent.
  • Easy fuse replacement with down-opened panel.
  • Front panel installation of VR for Max and SFS for easy adjustment.
  • Multi-LED display panel for clear operating condition indication.
  • Independent control of auxiliary powers (AC1, AC2) for all models.
  • Buffering output adjustment (SFS VR) built-in, with an adjustment range of 1 to 22 seconds, exclusive to phase control products.
  • Safety and aesthetics enhanced with top and bottom shielding covers, facilitating wiring installation.
  • Immediate system output switch-off in case of sudden 0.5 Hz power losses. Upon power restoration, output buffering prevents voltage surge, avoiding fuse burn-down.
  • Designed for main power specifications ranging from 200 to 480VAC.
  • Automatic power frequency detection for 50 to 60 Hz, eliminating the need for manual selection.
  • Automatic detection and display of power out-of-phase, SCR overheating, and fuse burn-down, with one set of alarm dry contact output.
  • Immediate system output stoppage in case of SCR overheating or fuse burn-down. Upon malfunction resolution and power restoration, output buffering prevents fuse burn-down.
  • Ready-to-use control signals including 420mA, 15VDC, 210VDC, 020mA, 05VDC, 010VDC, dry contact points, etc.
  • Triggering circuit and main board designed separately to safeguard the main board from damage during main circuit malfunctions.
  • European detachable control signal connector used for easy replacement without rewiring installation.

Outline description

Installation and ambient conditions

  • Install the power regulator vertically to allow for heat dissipation, leaving space on two sides.
  • Ensure ventilation holes in the control box follow the principle of upward air flow or use additional cooling fans.
  • Avoid installation in high-temperature or poorly ventilated areas. Otherwise, set the maximum operating capacity below 70% of the nominal capacity.
  • Avoid installation in areas with heavy water evaporation, acid, alkaline, or corrosive air.
  • Ambient humidity should be below 90%RH (no condensation).
  • Ambient temperature range: -10°C to 45°C.
