Murphy S10 Series - Manual

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 FLOAT
VOLTAGE
(V DC)
BOOST
VOLTAGE
(VDC)
Lead acid (6 cells) 13.6 14.1
12 V Ni-Cd (9 cells) 12.8 14.0
Ni-Cd (10 cells) 14.2 15.6
Lead acid (12 cells) 27.2 28.4
24 V Ni-Cd (18 cells) 25.6 28.1
Ni-Cd (20 cells) 28.4 31.2
•
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).
