General Notes:
  • Specifications are for nominal input voltage, 25°C and max. load unless otherwise stated.
  • Derate output power linearly to 80% from 90 VAC to 80 VAC input.
  • Please refer mechnical outline drawing for height of component above and below PCB for - 1xxx and 3xxx.
  • Class II version available. Add "-2" suffix at the end of the Model Number to Order. Enquire with EOS Sales Rep before Order.
    Notes:
  1. Ripple is peak to peak with 20 MHz bandwidth and 10 μF (Electrolytic capacitor) in parallel with a 0.1 μF capacitor at rated line voltage and load ranges.
  2. Min Load specified to meet cross regulation.
  3. Maximum current per output channel. Do not exceed total output power rating.
  4. Safety approved 47-63 Hz.
  5. For WLT40-3003 efficiency is 75 % typical.
