Murphy Modex BC700 Series Product Specifications

BC700/701 series
AUTOMATIC BATTERY CHARGERS
3 AMP CONSTANT CURRENT
The Modex range of 3 Amp constant current chargers
provide for the fully automatic monitoring and charging of
standby diesel generator battery packs.
The advantages of this type of charger are primarily:–
Rapid recovery of battery charge, equivalent to a
considerably higher rating 'taper' type charger.
Protection from overcharging. The unit switches off
automatically once the batteries are fully charged.
Prolonged battery life, from the reduction of gassing
and continual exercising of the cells.
When connected, the charger measures the battery
terminal voltage. If this is below a pre-calibrated threshold,
the unit outputs a series of charge pulses to the battery,
regulating the average current to a constant 3 Amps.
Between charge pulses, the BC700 continues to monitor
the battery terminal voltage. When the measured voltage
has climbed to a suitable threshold the charger turns off,
allowing the battery to decay back to the lower voltage
threshold before the cycle is repeated. The 'switch off'
and 'switch on' voltage thresholds are factory calibrated
according to the type of battery used:–
BC700 (12 V)
Lead
Calibration: Acid
Normal operation:
Switch on, VDC
12.6
Switch off, VDC
13.7
Boost operation:
Switch on, VDC
14.9
Switch off, VDC
15.7
The rate of the charge/decay cycle depends on the
capacity and condition of the battery and the static load
across it (the charger itself presents negligible load).
The 'boost' mode of operation may be selected by
linking two terminals, either through a remote panel
switch, relay or timer. This increases the switch on and
switch off voltage thresholds, and may be used for short
periods to increase the battery charge level.
The charge cycle state is indicated by two LEDs:
amber for 'on charge' and green for 'charge complete'.
Two –ve DC (open collector transistor) outputs are provided
for the remote signalling of 'on charge' and 'charger fail'
conditions.
The BC700 series uses an open-chassis, metal cased
design, suitable for bolt or stud mounting in an enclosed
panel. Electrical connection is by ¼" blade terminals on
the main PCB.
When ordering, please specify:–
a) Product type: BC700 (12V) or BC701 (24V)
b) Battery type: lead acid, or number of Ni-Cd cells,
or special calibration requirements
