1．Overview

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.

2．Features

v 12V / 24V voltage selection, the use of imported high quality DIP makes it more reliable and stable, easily toggle switch to select.

v Take Switch Power Structure, wide range of AC input voltage, small volume, light weight, high efficience.

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 safe.

v Charging voltage and current values can be adjusted at the scene by the potentiometer.

v BOOST boost function, short BOOST port can boost 1.0 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 3A.

v Suitable for 12V battery pack, rated charging current is 6A.

v Charging status LED indication: Power Indication (green), Charging Indication (red), filled with lights off.

3．Charging Principle

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.
