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.
Mechanical Details
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 9-36 VDC and 48 V for 18-75 VDC models.
