Notes

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.
