5.14.1 Series connection for increased output voltage
In this mode, two units are connected so that their outputs are summed. Set the Current of each
to the maximum that the load can handle without damage. It is recommended that d
odes be connected in parallel with each unit output to prevent reverse voltage during start up s
quence or in case one unit shuts down. Each diode should be rated to at least
Output Voltage and Output Current. Refer to Fig.5

The analog programming circuits of this power supply
