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 to accommodate special
charging requirements. High quality digital meters can be added (factory option) to allow
monitoring of output current and output voltage.
