FERRORESONANT BATTERY CHARGERS

C-CHARGER®AA SERIES™

AUTO EQUALIZE BATTERY CHARGERS

Electrically, the C-Charger is a paragon of efficiency and simplicity. It uses a ferroresonant transformer with integral self-regulation. It has been intelligently designed to be completely devoid of any complicated switching circuits that could possibly burn out. There are no tubes nor delicate electronics to fail or to cause radio frequency interference (RFI).

Voltage output to the batteries remains at a safe and constant DC level from full load to no load, even if AC power runs as high as 132 VAC or as low as 108 VAC. This automatic voltage regulation relieves strain on internal electrical components and lengthens the lifespan of the unit. All components are designed to operate safely and continuously in an ambient temperature as high as 122º F.

The Auto Equalizer Battery Charger is the first C-Charger to offer fully automatic equalizing. The advantages of automatic equalizing are clear:

no manual switching or settings, no waiting for power failure, no 9 to 24 hour overcharges, and no failure to return to float due to high load currents. The addition of an Auto Equalizer Charger expands the equalizing options of the C-Charger line, which also includes Float/ Equalize Switch, 0-24 Hour Timer, and 0-24 Hour Automatic Equalizer Timer.

If battery voltage drops below a set value (i.e. 25.5 VDC), the charger switches to the equalize mode and the yellow equalize indicator illuminates. The charger remains in equalize mode until the battery voltage reaches another set value (i.e. 28 VDC). This ensures that the battery is completely recharged and not cycled. At this voltage the charger is switched to the float mode and the yellow equalize indicator turns off.

If battery voltage remains low, a red low voltage alarm indicator illuminates. If battery voltage remains high,

a red high voltage alarm indicator illuminates. An optional summary alarm relay is available for remote locations. Adjustable low and high voltages permit users to tailor the charging system to specific batteries. Precise setting of these voltages is provided by fifteen turn potentiometers.
