REGULATED DC TO DC POWER CONVERTER

Battery Charger Converter

BC14 BC28jpgThe 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.
