Introduction
This all new single board design incorporates state of the art switchmode technology for
unmatched efciency and ultra-quiet operation. Multiple stages of ltering reduce radiated or
conducted noise to very low levels. Extra features include adjustable output voltage, audible
and visual indicators for low input voltage, low output voltage, over temperature and overload.
Safety features include reverse input protection, over-temperature shutdown, current limit-
ing, short circuit shutdown, and output overvoltage crowbar. Optional features include a dry
contact alarm relay output, and remote panel monitoring with On-Off control.
We are condent that you will get many years of reliable service from this Voltage Converter.
