Notes:
1. When measuring output ripple, it is recommended that an external ceramic capacitor (approx. 1 µF to 10 µF) be
placed from the +Vout pin to the -Vout pin for single output units and from each output to common for dual
output units.

2. These units should not be operated with a load under

4. Dual output units may be connected to provide a 10V, 24V or 30 VDC output. To do this, connect the load across
the +Vout and -Vout outputs and float the output common.
