Series Connections

Setting the Over-Voltage Protection

The master unit OVP should be programmed to the desired OVP level. The OVP of the slave units should be programmed to a higher value than the master. When the master unit shuts down, it programs the slave unit to zero output voltage. If a slave unit shuts down when its OVP is set lower than the master output voltage, only that unit shuts down and the remaining slave units will supply all the load current.

Setting the Over-Current Protection

 

 

Over-current protection, if desired, may only be used with the master

 

 

unit. When the master unit shuts down it programs the slave units to

 

 

zero output voltage.

Series Connections

 

 

 

SHOCK HAZARD For models up to 60VDC rated output, no point shall be more

 

WARNING

 

 

than +/-60VDC above/below chassis ground. For models > 60VDC rated

 

 

output, no point shall be more than +/-600VDC above/below chassis ground.

 

 

There is also a potential shock hazard at the IEEE/LAN/USB ports when

 

 

using power supplies with rated or combined voltages > 400VDC with the

 

 

positive output of the power supplies grounded. Do not connect the positive

 

 

output to ground when using the IEEE/LAN/USB under the above conditions.

 

 

 

 

 

Only power supplies that have equivalent voltage and current ratings can be

 

CAUTION

 

 

connected in series.

 

 

 

 

 

Two units of the same voltage and current rating can be connected in

 

 

series to provide up to two times the output voltage capability.

 

 

Because the current is the same through each element in a series

 

 

circuit, outputs connected in series must have equivalent current

 

 

ratings. Otherwise, the higher rated output could potentially damage

 

 

the lower rated output by forcing excessive current through it under

 

 

certain load conditions. Refer to the following figures for typical

 

 

series connections using either local or remote sensing.

 

 

It is recommended that diodes be connected in parallel with each

 

 

output to prevent reverse voltage during start up sequence or in case

 

 

one unit shuts down. Each diode should be rated to at least the rated

 

 

output voltage and output current of the power supply.
