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 and a dry 
contact alarm relay output.
Safety features include reverse input protection, over-temperature protection, current limiting, 
and short circuit protection with automatic recovery, input undervoltage shutdown, reverse 
battery protection and output overvoltage crowbar.
Optional features include a high quality digital volt/ammeter (factory install only), and remote 
panel monitoring with On/Off control.
