DRBC-1
DUAL RATE BATTERY CHARGER
DESCRIPTION
The DRBC-1 Dual Rate Battery Charger is a solid-state,
fully automatic device that will provide sufficient current to
maintain compatible rechargeable batteries at full charge re-
gardless of variations in line voltage or load.
Two charging modes are provided: FLOAT, which main-
tains a charged battery in fully charged condition and HIGH
RATE, which permits a discharged battery to be charged rap-
idly. The charger senses the battery condition by monitoring
the current drawn by the battery at a particular cell voltage. If
the battery attempts to draw more than a specified amount of
current from the charger, it will automatically switch to the
High Rate mode and maintain a high rate of charge current
until the batteries requirements are met. The DRBC-1 will
then automatically switch to the Float mode.
The DRBC-1 may provide system compatible battery su-
pervision, high rate indication and self-contained trouble in-
dications with audible trouble silence (with “ring-back”).
Over-current and reverse polarity protection are provided as
well as internal fuse protection.
The charger is enclosed in a louvered 16 gauge steel enclo-
sure 12" W x 13" H x 4" D (30.48 x 33.02 x 10.16 cm) with a
viewing window to readily show all status indicators without
opening the cabinet.
