OPERATION:
The
charger incorporates the latest NiCd battery charging techniques
to charge and maintain batteries at their optimum level.
It
uses a REFLEX charging action, which injects a pulse of constant
current into the battery followed by a short discharge pulse.
The battery voltage is monitored between these pulses so that
no errors are made due to internal impedances, resistors or
fuses.
The
charger only replaces the charge used by the battery and can
thus ‘top-up’ a battery that has only been used
for a short period of time. It will, of course, fully charge
a battery from it’s fully discharged state in about 8
to 10 hours and then automatically trip to it’s trickle
state.
In
the trickle state, the charger keeps the battery fully conditioned
and ready for use by its REFLEX charging action, which discourages
cell destroying dendrites from forming.
Batteries
can safely be left connected to the charger until ready for
use.
The
charger can also discharge a battery pack to it’s safe
‘discharged’ level of 1.1 volts per cell and once
this level has been reached will automatically trip to charge
the battery up again.
Should
a battery pack suffer from one or more short circuited cells,
it will detect this condition and alert the operator after
approximately 1.5 hours of charging, by flashing the LED.
Only
one Tri-Coloured LED per channel is required to indicate
the three conditions of Discharging, Charging and
Trickle. (Red, Amber,
Green).
To
ensure no battery can be excessively overcharged, each charge
is also timed, and should this time be exceeded, the charge
is terminated automatically.
The
CHARGER is presented in a robust steel enclosure intended
for industrial conditions and comes complete with a 1.5 metre
long standard mains power cord. The internal circuitry is
microprocessor based and is extremely reliable, reducing maintenance
to a minimum.
