Key Features

1. Encapsulated Construction
   • Fully epoxy‑encapsulated core and coil assembly is impervious to moisture, dust, and corrosive environments.
   • Rigid structure withstands vibration and mechanical shock in industrial settings.
2. Dual‑Voltage Flexibility
   • Dual primary (240/480 VAC) and dual secondary (120/240 VAC) windings support multiple wiring configurations.
   • Eliminates need for multiple transformers; reduces inventory and installation costs.
3. High Reliability & Safety
   • Copper windings ensure high efficiency (≥98%) and low heat generation.
   • 100 °C temperature rise rating provides robust overload capability.
   • Pressure plate terminals and epoxy‑anchored terminal boards prevent loose connections.
4. Economical & Compact
   • Cost‑effective alternative to high‑inrush machine‑tool transformers.
   • Space‑saving footprint ideal for installation in control panels and tight enclosures.
5. Harmonic Mitigation
   • K1 factor design handles typical harmonic loads in modern control systems without excessive overheating.

Application Scenarios

• Industrial Control Panels
  • Supplies stable 120/240 VAC power to PLCs, relays, contactors, timers, and indicators.
• HVAC Systems
  • Powers control circuits for fans, pumps, chillers, and building automation controls.
• Signal & Alarm Systems
  • Provides isolated, noise‑free power for security alarms, fire alarms, and emergency lighting.
• Lighting Circuits
  • Steps down voltage for control of industrial lighting, emergency lights, and low‑voltage lighting systems.
• Circuit Isolation
  • Isolate sensitive control circuits from noisy mains to reduce EMI and improve system stability.
• Commercial & Institutional Buildings
  • Used in manufacturing plants, hospitals, schools, and office buildings for reliable control power。
