1.2.7 Parallel operation
PU power supplies of the same output voltage and current rating can be paralleled in master-slave
configuration with automatic current sharing to increase power available.
1.2.8 Output connections
Output connections are made to rear panel bus-bars for models up to 60V and to a 4-terminal wire
clamp connector for models above 60V rated output voltage. Either the positive or negative
terminal may be grounded or the output may be floated. Models up to 60VDC Rated Output shall
not float outputs more than +/- 60VDC above/below chassis ground. Models >60VDC Rated
Output shall not float outputs more than +/-600VDC above/below chassis ground. Contact factory
for assistance with higher float voltage applications.
Local or remote sense may be used. In remote sense, the voltage drop on the load wires should be
minimized. Refer to the specifications for the maximum voltage drop value.
1.2.9 Cooling and mechanical construction
The PU series is cooled by internal fans. At the installation, care must be taken to allow free airflow
into the power supply via the front panel and out of the power supply via the rear panel. The PU
power supplies have a compact and lightweight package, which allows easy installation and space
saving in the application equipment.
