General Notes:
  • Fan output voltage tolerance is +/-20 %. During V1 full load, VFAN needs min. 20 mA load to be within regulation band.
  • Peak current for fan output is 1 A.
  • Class 1 products have an Earthing tab and Class 2 version Enquire with EOS Sales Rep before Order.
  • 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.
  • When used in Cover Kit, de-rate output power to 70 % under all operating conditions.
    Notes:
  1. Ripple is 2 % up to 20 % load and < 1 % above 20 % load. Ripple is peak to peak with 20 MHz bandwidth and 10 μF (Tantalum capacitor) in parallel with a 0.1 μF capacitor at rated line voltage and load ranges.
  2. Combined output power from V1 and VFAN should not exceed the total output power rating.
Signals
Power Good Signal TTL signal goes high after main output reaches 90% of its final set value, delay is 0.1 to 0.5 s.
wlt20
Power Fail Signal TTL signal goes low at least 1ms before output falls to 90% of its set value due to mains failure.
