Notes
1. Ripple & noise is measured with a 10 µF tantalum capacitor and 1.0 µF ceramic
capacitor across output.
2. Logic compatibility: Ref to -ve input. Module On = open circuit.
Module Off = <0.8 VDC.
3. Add suffix ‘N’ to the model number to receive the unit with negative logic
Remote On/Off.
4. Input current specified at 24 V for 10-36 VDC models and 48 V for
18-75 VDC models.
5. Add an external capacitor of 100 µF minimum to maintain specified regulation.
