Notes

1. Input currents specified at nominal 24 V or 48 V input.

2. Cross regulation is ±5% when one output is at 100% and the other is varied between 25% and 100%.

3. Measured with 1 µF ceramic capacitor across output rails.

4. External input capacitor required Nippon Chemi-Con KY series 220 µF/100 V or equivalent.

5. Non-standard versions can have Remote On/Off function and pin removed.
