OVERVIEW
BAC1205N/2403N battery charger, adopts the latest switch power components, is speciallydesigned for charging lead-acid starting battery according to its property. This charger is suitable for lead-acid battery long-term supplementary charge (float charge).
PERFORMANCE AND CHARACTERISTICS
Product with the following characteristics
- Designed in switching power structure, wide range of AC voltage input, small volume, light weight and high efficiency;
- Two-stage charging method (constant current firstly and then constant voltage), fully considering charging property of the lead-acid battery, can avoid overcharging and extent extend the battery life to the fullest;
- With short circuit and reverse connection protection;
- Suitable for charging 12V or 24V batteries with corresponding model BAC1205N or BAC2403N;
- LED display: charging indication and full charged indication;
- Easy installation: guide-rail way installation, screw mounting installation;
- Built-in terminals, flame retardant plastic shell.
CHARGING PRINCIPLE
According to charging property of the lead-acid battery, BAC1205N_BAC2403N battery charger uses 2-stage charging method and charge mode is “constant- current”. When battery voltage is under the threshold, it is charging in constant-current mode; when the battery voltage is higher than the threshold, the charging current is decreasing as the battery voltage is rising until it reaches the set voltage, and then charge mode is turned into “float charge”. Charge current is gradually reducing and battery voltage is rising up to the set value. When charging current is lower than 0.3A, the battery is basically fully charged (charging indicator eliminates). Afterwards, charging current will offset self-discharge of the battery. Thus the charger can maintain a full charged condition and extend the battery life.

OPERATION
BAC1205N series panel drawing description
- Connect terminals L and N to alternating voltage (100~277)V using BVR 1mm2 or above multi-strand copper line.
- Connect B+ and B- to battery positive and negative using multi-strand BVR1.5mm2 or above copper wires.
- Charging: charging indicator (Red), illuminating when charging current exceeds 0.5A.
- Full Charged: full charged indicator (Green), illuminating when charger is no-load or battery is full charged.
NOTE
- Because there is diode and current-limiting circuit inner the charger, it can be used parallel with charger of generator, and there is no need to disconnect the charger when cranking.
- During genset is running, high current will cause voltage drop in charging line, so recommend separately connectingto battery terminal to avoid disturbance on sampling precision.
CASE DIMENSIONS AND INSTALLATION
Installation 1 (screw-fixed installation)
- M4 screw is recommended.
Installation 2 (guide-rail installation)
BATTERY TYPE SELECTION
There are two types of battery for choose
- BAC1205N is designed for 12V battery with the maximum output current 5A.
- BAC2403N is designe d for 24V battery with a maximum output current 3 A.
Please pay attention to the charger model when placing orders.
