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 prole 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.
