Introduction
All new Current Mode switching design offers increased power and reliability in a compact
package. Extra input and output filtering reduce EMI to extremely low levels. Reliability
features include an input fuse, thermal shutdown, current limiting, reverse battery hookup
protection and output short circuit shutdown with automatic recovery. The output voltage is
easily adjusted 1.0 volts above or below the standard output voltage. The model BCD615R
Battery Charger supplies either
12, 24, 32 or 48 VDC from a 110, 250 or 300 VDC
power
source. High quality digital meters can be added (factory option) to allow monitoring of charg-
ing current and charging voltage.
