Introduction
This all new single board design incorporates state of the art switchmode technology for
unmatched efciency and ultra-quite 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 and over temperature. Safety
features include reverse input protection, over-temperature shutdown, current limiting, short
circuit protection with automatic recovery, input undervoltage shutdown, and output overvolt-
age crowbar. Optional features include a dry contact alarm relay output, and remote panel
monitoring with On/Off control.
We are condent that you will get many years of reliable service from this Power Supply.
