Overview

It converts primary voltages of 208V, 240V, 277V, or 347V to secondary outputs of 120V or 24V at 50/60Hz. The transformer features copper windings, an 80°C temperature rise, and Class 130°C insulation for reliable operation. Primary and secondary terminations are via terminal blocks for direct wiring. Load inrush ratings at 40% power factor are 530VA (5% voltage drop), 750VA (10% voltage drop), and 950VA (15% voltage drop). Full load power loss is 35.3 watts. This transformer is ideal for powering control circuits, relays, contactors, PLCs, and other low-voltage devices in electrical systems. Its open construction allows for flexible mounting and natural ventilation, reducing heat buildup and extending operational life. The unit supports standard DIN rail mounting for easy installation in control panels.
  • High inrush and continuous operation design handles relays, solenoids, contactors, and timers.
  • Copper-wound coils, durable insulation, and silicon steel laminations deliver stable, consistent voltage and long life.
  • Welded core and base construction ensure mechanical strength and easy installation.
  • Vacuum-impregnated coils improve thermal performance and protection.
  • DIN rail compatible for easy installation
