TRM Screw for Adjusting the Output DC Voltage

The DC output connectors on the power supply have a power range of 
45.0V to 55.2V. The default is 48V. You can adjust the output voltage with 
the TRM screw on the front panel. Here are the guidelines:

A voltmeter is required to adjust the DC output power.

You should verify and adjust output power before connecting 
powered devices to the power supply.

The TRM screw configures the voltages on both sets of DC output 
connectors together. You cannot set the connectors separately.

Refer to the powered device’s installation guide for input power 
requirements.
