Murphy S10 Series Specification Sheet

S10 series
AUTOMATIC BATTERY CHARGERS
RATINGS TO 10 AMPS
The S10 is a constant potential, open-chassis battery
charger, suitable for use with either 12V DC or 24V DC,
lead acid or Ni-Cd systems. Although primarily designed
for the diesel generator market, the charger may be
configured for use in a wide range of unattended industrial
applications where standby power is required at all times.
Each unit consists of a transformer, rectifier and control
circuitry. The charger monitors the battery voltage and
delivers as much current as the cells require up to the
current limited maximum, giving a rapid recovery of charge.
Once the battery is fully charged, the charger provides a
low trickle charge to maintain the cells for an indefinite
period at a pre-set float voltage, without overcharging, plus
any additional current required to support a static load.
Also included is a range of on-board fault monitors
complete with volt free relay contacts for remote
alarm signalling.
Standard Features
Boost function, operated by remote link.
Indication by amber LED.
Adjustable float and boost voltage levels to meet with
a range of battery types, static loads and operating
conditions. Standard calibrations are:-
BATTERY TYPE
Lead acid (6 cells)
12 V Ni-Cd (9 cells)
Ni-Cd (10 cells)
Lead acid (12 cells)
24 V Ni-Cd (18 cells)
Ni-Cd (20 cells)
Adjustable current limit. Standard versions have a
10 Amp limit, but this may be adjusted downwards
where required (e.g. for lower capacity batteries).
Output short circuit protection.
Protection against reverse polarity battery connection
via fuse and red warning LED.
3 alarm monitoring circuits: 'charge fail', 'low battery
voltage' and 'high battery voltage', complete with
volt-free relay outputs and LED indicators. The low
battery voltage alarm features a fixed time delay of
approx. 60 secs. to inhibit the signalling of a fault
during normal battery loading (e.g. engine cranking).
Electrical connection of the battery, boost and charge
monitoring relays is via ¼" blade terminals. The AC supply
is connected through separately mounted screw terminals.
When ordering, please specify:-
a) Product type (S10 series)
b) Nominal output voltage (12 or 24 V DC)
c) AC supply voltage (240 or 110 V)
d) Battery type (Lead-acid, or Ni-Cd and number of cells,
or special calibration requirements).
