General Description

Model NBC-1027 Professional NiCd Fast Charger/Conditioner is designed for rapid charging of NiCd battery packs consisting of 1 to 10 cells. With an optimised nominal charge current of 1.5C, it is capable of charging packs in approximately 45 minutes from a completely discharged state. In everyday use charge times as short as 15 minutes may be achieved.   The unit differs from conventional chargers in that it employs a novel “burp” charge technique designed to eliminate memory effects associated with NiCd cells, help restore the condition and charge capacity of old batteries, maximise capacity in everyday use and to extend batteries’ operational lifetime. The technique utilises a strategic series of alternate charge and discharge pulses which carefully control both the internal bulk and localised cell chemistry around the electrodes during charging.   The NBC-1027 employs a multi-stage pulsed current charging regime which includes polling (automatic detection of battery connection and removal and charge initiation), soft start (to ease degraded or cold cells into a state suitable to accept fast charging), fast charge, topping charge and maintenance charge. Premature charge termination is eliminated through the use of a negative delta peak algorithm to determine the optimum termination point. It also incorporates detection of damaged cells which are unable to accept fast charging, and two safety timers. A fully automatic deep discharge-charge mode can be initiated for cycling of old battery packs which have lost their charge capacity due to extended use with conventional chargers. or new batteries to bring them into their full service capacity. Large coloured LEDs clearly indicate the various charge stages throughout the process.   The unit comes in a compact, rugged steel/aluminium case with a hard paint finish. The fixed 2m mains lead is terminated with a moulded 5A fused plug, while the output connection is via twin gold plated 4mm terminal posts which can accept a wide range of standard battery connection leads or unterminated wires. All units come with comprehensive operating instructions and a full one-year guarantee. A full Technical & Operating Manual is available as an option.
