Input currents specified at nominal 24 V or 48 V input.
Cross regulation is ±5% when one output is at 100% and the other is varied between 25% and 100%.
Measured with 1 µF ceramic capacitor across output rails.
External input capacitor required Nippon Chemi-Con KY series 220 µF/100 V or equivalent.
Non-standard versions can have Remote On/Off function and pin removed.
