Introduction
The PWI320 Intelligent Power Supply delivers a full 300 watts of output power for
communications, control or a wide variety of other devices. It comes standard with easy to use
color coded DC connection terminals.
The Power Supply uses advanced Power Factor Correction circuitry on the AC input so it will
work from any standard AC voltage anywhere in the world and use the electricity in the most
effective and efficient way. LLC Resonant Converter technology allows Zero Voltage/Zero
Current switching on the Primary or high voltage side of the main power transformer, and Active
Rectification on the Secondary or low voltage side ensures maximum efficiency and the lowest
Electromagnetic Interference (EMI) so the PWI320 will not interfere with sensitive voice or data
RF communication equipment.
The Power Supply is preset to the same voltage as a fully charged battery of the nominal output
voltage (ie. 13.6V for a 12V model, etc.). The voltage can be adjusted over a reasonable range
using the PowerWizard software that is free to download from www.analyticsystems.com.
Seven dual color LEDs clearly indicate output current levels as well as indicating faults with the
Power Supply. The ‘PowerWizard’ software adds advanced programming and monitoring as well
as a graphing function through the built in USB port.
Safety features include Power Supply over temperature shutdown, current limiting, short circuit
protection, input under voltage shutdown and output over-voltage protection all with automatic
recovery.
The Power Supply requires no maintenance other than the occasional wipe down to remove any
accumulation of dust or dirt.
