LBC Battery Charger Generator Accessories For Volvo Diesel Generator
LBC series Battery Charger is a charger which using latest switch power programs, and
specifically for the charging characteristics of lead-acid batteries designed for engine start, suitable
for lead-acid batteries of long-term supplemental charge (float), you can select the appropriate one
according to the selection table.
v Take Switch Power Structure, wide range of AC input voltage, small volume, light weight, high
v Using Multistage Charging Method (constant voltage, constant current, trickle float, full stop)
automatic charging, fully charged according to the battery charging characteristics to prevent
lead-acid battery overcharge, can maximize battery life.
v With the flow, short circuit, reverse polarity protection.
v With Charging Failure Alarm Output Function (Passive Relay Contact), more convenient and
v Charging voltage and current values can be adjusted at the scene by the potentiometer.
v BOOST boost function, short BOOST port can boost 1.5 V of output voltage, with compensation
for rechargeable dissatisfaction in the winter, and better for the old battery.
v Suitable for 24V battery pack, rated charging current is 5A.
v Charging status LED indication: Power Indication (green), Charging Indication (red), filled with
Use 2 stages of charging method according to the battery charger characteristics. First stage
is “Constant Current Mode”, namely before the battery terminal voltage lower than preset value,
charging is for the constant current charging; Second sage is “Float Mode”, means when terminal
voltage of battery charger is higher than the preset value, the charging current decrease with
battery charger terminal voltage rising, then charging into a float charge.
When charging current is less than 0.5 A, terminal voltage is gradually increased to reach a
preset constant value, the battery has been basically full (charging indicator light off), then the
charging current is only offset the battery self-discharge, and harmless even long charging time, it
namely charger can maintain full status, and ensure the life time of battery.
5.1. L, N connect to AC 100-240 V, using BVR1mm²multi-strand copper wire.
5.2. B+ connect to battery, B- connect to storage battery, using BVR1.5mm²multi-strand copper wire.
5.3. CHARGE FAIL Charging Failure Output Terminal.
5.4. BOOST boost port, short BOOST port can boost the output voltage 1.5 V, also filled with battery
in winter.Suggested Use: short-circuit this terminal when temperature is below 10℃ and battery
5.5. POWER: power supply indicator, illuminated when the charger is operating normally
5.6. CHARGING: charging indicator, illuminated when charging current exceeds 0.5 A while
extinguished when charging current has fallen below 0.5 A.
5.7. VOLT: charging voltage regulator-potentiometer, Adjusting the voltage at the scene, it need to
disconnect the battery from the charger, while measuring the output voltage of the charger, and
adjusting the voltage potentiometer (VOLT), until transferred to a suitable voltage.
² Suggestion: 12 V battery float voltage is at 13.8 V, 24 V battery float voltage of 27.6 V.
Factory is a according to the adjustment and calibration, non-professional workers do
not adjust at will.
5.8. AMP: charging current regulator-potentiometer, Output connected battery, take charging current
measurement when 24 V battery pack is not higher than the charging voltage 22.0 V; 12 V
battery charging voltage is not higher than 11.0 V, via adjusting the current potentiometer to set
the appropriate charging current
5.9. FUSE: Output fuse; Rated current: 10 A. If connected in the wrong way, the fuse will be burnt out
and then voltage free. In this case connect cables correctly, replace the fuse and the system will
continue to operate normally
5.10. Insurance Replacement Steps:
Use a flat screwdriver to harder press into it, while counter-clockwise back to tighten it, then
pull out the knob part.
Change new insurance after extracting it, and insert it into the fuse holder inside, then use a
flathead screwdriver to harder press into it, meanwhile clockwise twist it.
² Tips: Improper operation or excessive force most likely to be damage fuse holder.
² Mark: 1) This charger is connected to the internal output diode and current-limiting circuit,
charger and charging generators in parallel on the engine used is not required when
starting off the charger.
2)When applied to the generator, cause of large charging current, it will cause a pressure
drop in the charge line. it is recommended that a separate charging cable connected to
the battery terminals to avoid affecting the sensor sampling accuracy.
