These are fully regulated switching power converters (switchmode), designed
for the charging of of 24 volt lead acid batteries 12 volt vehicles, marine, military, PLC, and cell tower applications. These
are attractive, reliable, robust DC to DC battery chargers with high power output. They are relatively immune to vibration and
shock, and come in three versions, heavy duty, water proof and military grade. Designed specifically to work in Day Cab HVAC
transport vehicle applications.
These converters have common negative, so they are not fully isolated, but can be used
for almost all 12 volt applications. They feature a spark-free connection, wide temperature range and 3 year warranty. They all
have conformal coating on the electronics for use in marine environments
