Features

  • Compact DIN rail design with reinforced isolation. Ultra compact footprint with galvanic isolation rated up to 3.0 kVac between input and output, suitable for dense control panels and safety-critical circuits
  • Wide input voltage with reliable operation in harsh environments. Supports universal AC input and delivers full rated output across a broad operating temperature range from -10°C to +55°C, making it well suited to industrial cabinets and field installations
  • High efficiency for reduced heat and energy loss. Delivers efficiency of up to 88 percent, helping minimise heat build-up inside enclosures and improving long-term reliability
  • Low earth leakage for sensitive installations. Designed with earth leakage current below 0.5 mA at 240 Vac, supporting compliance in installations with strict leakage limits
  • NEC Class 2 and Limited Power Source compliant. Certified to NEC Class 2 and LPS requirements, simplifying approval for control, automation, and safety-related applications
  • Comprehensive built-in protection. Integrated overvoltage, overcurrent, and overtemperature protection helps safeguard connected loads and reduce downtime
