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	BOOST
		VOLTAGE	VOLTAGE
		(V DC)	(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).
