1.0 Description
The 491198-36 NiCd Battery Fast Charger is a dual power source
battery charger. It charges 3.6 volt 1400 mAH NiCd batteries and is
powered by 120-240 Vac line power or 12.5 Vdc. The 491198-36 uses a
-(dV)/(dT) (negative delta V) technique to determine when the battery is
fully charged, typically one hour. With this technique, the charge state of
the battery has no effect other than shortening the charge time.
Housed in a rugged enclosure, power enters the battery charger through
a power entry module, which contains the fuses, or an optional cigarette
lighter plug adapter. LEDs and the label on the front face of the unit
provide operating status. The battery charger connects to the device
being charged through a short cord terminated with a power jack.
An integrated circuit within the charger monitors the battery voltage and
controls the charging functions according to the charge state of the
battery.
