BC14, BC28
REGULATED DC TO DC POWER CONVERTER
Battery Charger Converter
The BC-Series is a pulse width modulated DC to DC converter that provides regulated output power. These converters will transform an unregulated 28Vdc to a regulated and adjustable DC output.
The BC-Series is primarily designed to charge or trickle charge Ni-Cad, lead acid and jell cell batteries. The charging voltage and current limiting point is adjustable.
Features:
- Provides an output to indicate "charged" or "charging" state.
- Positive logic and regulation for output overvoltage protection.
- Output current limit is adjustable via an internal trim pot.
- Designed to meet various portions of MIL-Std-704 notice 3, Mil-Std 202 and Mil-T-5422F class 1A.
