Characteristics: |
"F" Series
Float chargers are designed to provide optimum life for batteries used in standby applications where
charging is continuous. The chargers deliver a constant voltage of 2.25 to 2.30 volts per cell which
allows the battery to seek its own current level and maintain itself in a fully charged condition.
This series is best suited for burglar and fire alarm equipment, emergency lighting, memory protection
or UPS systems where the battery serves as back-up power to th AC source. |
"A" Series
Automatic dual rate chargers sense battery requirements and automatically switch from the fast charge
to float mode, or vise versa. LED's provide visual indication of the charging mode. Automatic chargers
combine the advantages of float and cycle chargers; recharge time is short yet batteries are safe from
being overcharged. This charger is safe for cyclic applications where recharge time is critical and the
battery may be left on charge indefinitely. As a result charging is fool proof.

Notes:
Recharge time depends on the depth of the preceding discharge and the output current
of the charger. To determine the approximate recharge time of a fully discharged battery,
divide the batteries capacity stated in amp. hrs. by the rated output current of the charger
(amps) and multiply the resulting number of hours by a factor of 1.75 to compensate for the
declining output current during the charge cycle. If the amount of amp. hrs. discharged from
the battery is known, use it instead of the batteries capacity to make the calculation.
When charging batteries in series
(positive terminal of one battery is
connected to negative terminal of the other) all batteries in the string will receive the same
amount of charge current, individual battery voltages may vary.
When charging batteries in parallel
(positive terminals are
connected with positive terminals, negative terminals with negative) all batteries in the string
are subject to the same charge voltage, but the charge current each battery receives can
and will vary until equalization is reached. |
