DVI-7200-PS Series
Quick Start Guide
Distribution Power Supplies
Introduction
Many AV products require the use of external AC power supply units (PSU) to power their internal
electronic circuitry. These external PSUs (wall warts) can pose a major challenge to system designers as
they occupy valuable space within AV equipment racks where there are a limited number of AC outlets.
Furthermore, some external PSUs are poorly designed and ill-suited for use in high prole applications.
DVIGear’s DVI-7200-PS Series Distribution Power Supplies are engineered from the ground up for 24/7
mission critical applications. These units offer an unprecedented level of reliability with an MTBF of
greater than 100,000 hours. Even at full load these power supplies operate at less than 70% of their
rated maximum power, thus providing headroom that further enhances long-term reliability.
These units are housed in rugged 1U rack-mountable enclosures. They accept AC line voltages autoranging from 90-264 VAC and AC line frequencies from 47-63 Hz. Four models are available, with
output voltages of either +5VDC or +12VDC and a choice of either 10x or 20x outputs. All outputs
include extensive protection against overload, over-voltage and over-temperature. All outputs utilize
secure twist-lock DC power connectors. Several types of power supply extension cables are available
that support the full range of DVIGear products.

Installation
1.) Install the distribution power supply in a rack mount environment using mounting ears. Care
must be taken to ensure that the airow is not restricted in any way.
2.) Connect the AC power input cable to a power source and to the distribution power supply.
3.) Connect devices to be powered to the DC outputs of the unit using the appropriate power
supply extension cables, see page 4.

4.) Turn the distribution power supply on using the Power Switch at the rear of the unit. Check to
make sure the power LED on the front panel is lit and the cooling fans are operating.
5.) The unit is ready for use.
