2 / 4 page QSB75/100 Models and Ratings 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 9-36 VDC and 48 V for 18-75 VDC models.
