Introduction
The BCH10W Step Down series of Battery Chargers supply up to 10 amps of charging current
at 12, 24, 36 or 48 volts from any higher voltage between 20 and 80 volts DC in an IP66 rated
watertight and EMC shielded enclosure for use in automotive, heavy equipment, marine,
industrial, rail or alternative energy environments. The output voltage is configured to allow
permanent connection to the battery.
The standard BCH10W model offers a Deutsch connector on a pigtail input/output cable and is
designed to be water resistant to IP66.
The BCH10Y is an upgraded version with the same connections that is individually tested to
meet IP67.
The all surface mount high frequency design offers higher reliability, higher efficiency (more
than 91%), more power (up to 544 watts at 48 VDC Out) and minimum size. Two LED indicators
show the presence of input power, and when the unit is charging (output current is greater
that 2 amps).
The unit has reverse input protection, reverse battery connection protection, output
overvoltage protection and features spark free connection to the battery. Smart Ideal Diode
output circuitry prevents any reverse current flowing from the battery back into the converter.
