*The "NRTL/C" mark appearing next to the CSA stamp indicates that the charger was also tested to meet U.L. requirements (UL1310). Under the provisions of this agreement, CSA and U.L. can now test each others' specifications and thus obtain approval for both organizations.
**PSC-122000A, PSC-241000A and PSC-124000A can be switched to accept 115 VAC or 230 VAC input (47-63Hz) allowing usage both here and abroad.

***PSC-124000AP when be used when the automatic dual rate charger is used like a power supply. As such it can supply a continuous load current up to 2.5A, yet still switch into float mode (13.8V) when the battery is fully charged.

"A-C" Series
“A-C” series chargers are new “switching” type devices which operate without the use of transformers. I.C.’s control and regulate current and voltage and automatically switch from the higher fast charge voltage to the lower float voltage when batteries are very close to being fully charged. At the float voltage it is safe to leave the battery connected to the charger indefinitely, making charging pretty much fool-proof.
In the fast charge mode voltage goes up to 2.45V +/- 0.05V before switching, in the float charge mode voltage is held between 2.25- 2.30V/cell.
This charger is ideal for cyclic applications where recharge time is critical and timely charge termination cannot be counted on. This charger ensures optimum battery performance & service life.
A-C Series Specifications Sheet
"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.
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.
