Operator Manual, Supercharger 60 R3.0

1.INTRODUCTION AND SYSTEM DESCRIPTION

Congratulations! You now own the finest battery Charger-Analyzer available today. The Supercharger is a precision instrument designed to charge and analyze NICKEL-CADMIUM, LEAD-ACID and other rechargeable batteries exactly as recommended by the battery manufacturers.

The simple to set controls plus the condensed operating procedure found on the front panel makes the Supercharger a very easy to operate CHARGER/ANALYZER, which combined with easy to read CURRENT, VOLTAGE, TIME and STATUS indicators, makes it also a very simple unit to monitor.

The Supercharger is also designed for speed, for it can charge two batteries, (actually, any number of batteries where the total number of cells is 50 or less), at maximum currents, and it can also discharge two batteries at reduced currents, or one battery (25 cells or less) at maximum current.

The Supercharger also provides a Voltage Control enhancement that allows the Charger- Analyzer, originally designed for Constant Current operation on Nickel-Cadmium batteries to also be able to handle Lead-Acid and other type of rechargeable batteries, where the end voltage is a more reliable indicator of the state of charge (as opposed to Nickel-Cadmium batteries).

Dependability is another great plus of the Supercharger. 100% SOLID STATE circuitry requires no scheduled maintenance. No relay contacts to inspect and clean. No high current carrying contacts to arc and burn. A simple performance verification procedure is all it takes to determine if the instrument requires re-calibration or repair.

This instrument is also protected against certain internal performance deviations and programming errors, plus it is also designed to sense certain battery abnormalities to protect the instrument and battery from possible damage. In the event that any malfunction takes place, VISUAL and AUDIBLE indicators will turn on, alerting the operator and preventing any further operation of the unit.

The Supercharger Battery Charger-Analyzer System is comprised of the Charger-Analyzer, the Temp-plate, the Battery Cable and several accessories.

The Charger-Analyzer is basically a precision programmable constant current source (for charge) and a programmable constant current sink (for discharge) combined with voltage and temperature sensing circuits for total battery monitoring.

The specially designed circuitry provides a performance not achieved by any of the older conventional battery charging methods. The Supercharger will deliver current into a short circuit or a battery or combination of batteries totaling 50 cells, within ±1% of the programmed value, independent of line voltage variations (within ±10% of the nominal line voltage).

The control circuitry of the Charger-Analyzer consists of a CONTROL SWITCH, a CLOCK, a TIMER, a CURRENT CONTROL, a SYSTEM MONITOR, a POWER REGULATOR and a VOLTAGE CONTROL CIRCUIT. See Figure 1

The CONTROL SWITCH receives the function commands from the function selector switch on the front panel and outputs control signals to the rest of the circuit boards as well as to the charge SCR'S and discharge transistors.
