General Notes:
- Single output models deliver 65 W, except WLT60-1000 (50 W). Triple output models deliver 60 W, except WLT60-3003 (45 W).
- 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.
- Please refer mechnical outline drawing for height of component above and below PCB for - 1xxx and 3xxx.
- Class II version available, Add "-II" suffix at the end of the Model Number.
Notes:
- 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.
- Min Load specified to meet cross regulation.
- Maximum current per output channel. Do not exceed total output power rating.
- Safety approved 47-63 Hz.
- For MWLT60-3003 efficiency is 75 % typical.
