2. Single output models deliver 65 W, except MWLT60-1000 (50 W).
Triple output models deliver 60 W, except MWLT60-3003 (45 W).
3. Maximum current per output channel. Do not exceed total output power rating.
4. 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.
5. Safety approved 47-63 Hz.
6. Min Load specified to meet cross regulation.
7. Add -II suffix to order Class II product.
8. Specifications are for nominal input voltage, 25oC and max. load unless otherwise stated.
9. Derate output power linearly to 80% from 90 VAC to 80 VAC input.
11. When used in Cover Kit, de-rate output power to 70 % under all operating conditions.
