On/off control can be made via separate control for individual units (refer to Fig 1-2), or via single
control as shown in Fig 3-1.

Up to 3 units can be used for increased output voltage.
It is recommended that diodes be connected in parallel with each unit output to prevent reverse
voltage. Each diode should be rated to at least the power supply rated output voltage and output
current.
