    • Universal input mains range:
      • input voltage 90 - 264 VAC
      • frequency 45 - 65 Hz
    • Single-output voltage: 12 V at 1 A continuous operation
    • Standby mains consumption: < 30 mW at 230 VAC
    • Average efficiency: > 80%
    • Fully protected against faults (overload, feedback disconnection and overheating)
    • EMI: according to EN55022-Class-B
