2.0 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.
