SBC-2220 , 20A
70 AH - 200 AH
SBC-2225 , 25A
80 AH - 250 AH
C. Battery Charger Installation and Connection
Observe the warnings & safety precautions before rushing to install and operate the charger.
Check battery condition, fill up cells for wet battery, clean battery poles.
Secure the battery charger in a well ventilated place, make sure the mounting surface is flat and without soft covering material or loose paper sheet. The air intake is at the bottom and air outlet at the back. Make sure both intake and outlet are not blocked.
Never place charger on top of battery.
Plug in the AC mains and turn on Power Switch , the Charger On LED and the Float LED should be on green indicating Charger is in good order for charging lead acid battery.
Before connecting or disconnecting the charging cable, turn off the Power Switch and unplug AC cord from the mains.
First connect the Red cable to Positive + terminal of charger and the battery Positive + Pole. Then connect the Black cable to the
Negative – terminal and the Negative – Pole of the battery.
Make sure all the connections are secured and well tighten up, double check on the correct polarity.
Double check again for correct selection of Slide Switch 1 at Charger Mode, Switch 2 for Battery type and Switch 3 for Float
Voltage setting value.
D. Normal 3 Stage (IUoU) Charging Operation
The 3 stage IU0U charge algorithm ensures fast , complete and at the same time gentle charging of the lead acid battery.
Fig.3
Stage 1. THE I-PHASE. The constant current charging , Bulk LED is on.
Normally the battery is charged at constant maximum current until it rises to the selected Absorption voltage level.
The charging voltage changes with the battery voltage.
If the initial battery voltage is less than 20.5V due to deep discharge, the bulk charge current is reduced to half of the maximum until battery voltage rises over 20.5V.
Stage 2. THE UO-PHASE . The constant voltage charging , Absorption LED is on .
Battery Type Selection : Gel : 28.2V / AGM: 28.6V
/ Wet : 28.8V / Calcium : 31.1V
When the battery voltage rises to the selected Absorption voltage level, the charging switches to Constant voltage charging and battery is over 85% full. The battery is kept at this high voltage while the current reduces gradually to set value at which the charger automatically switches to Float Stage.
Stage 3. THE UO-PHASE. The constant voltage charging , Float LED is on.
Float Voltage Selection : 26.4V / 27.0V / 27.6V
In this stage , the battery is full and only takes in the amount of current necessary for maintaining the capacity. The float voltage is preset independently by user according to the type of battery such that battery can be connected permanently to the charger when it is not in use.
E. Manual Equalization Charging for wet type battery only
Wet lead acid battery requires periodic high voltage charging (about 10% overcharge absorption voltage) to balance the voltage of each cell, reverse the high concentration of electrolyte at the bottom and clear up large sulfate crystals on the plates. You can use the Calcium–Calcium selection to perform the manual equalization by carefully following the battery maker’s recommended frequency and duration.
Make sure to manually switch off charger when time is up.
Take special precautions as battery will emit explosive gas during equalization charge.
F. Dual bank charging
This feature is for caravans, and vehicles with two separate batteries.
The two batteries must be of same chemical make up and type to avoid over and under charging because only one setting of charging profile for both.
Two batteries are charged simultaneously and the battery with the lowest level gets most share of the current in the Bulk charge stage until it is up to the same voltage level of the second battery (battery with higher initial level).
Both batteries will go to the Absorption and the Float Charge at the same time.
G. Power Supply / 2 Stage Charger Mode (see Fig.4)
At this mode the Charger On (5) LED becomes red color and only Bulk and Float LED will function. The bulk LED will be off when battery is charged to about 80% full.
The 3 stage charger becomes a 2 stage charger or as power supply in this selected mode because 3 stage charger overcharges battery with external load.
This selected mode is intended for use to charge battery with external load such as caravan or other battery and external load combination.
A 2-Stage charger can be used as a combination charger/power supply. An external load can draw current from the charger while the charger is recharging a battery. The charger doesn't care how much current is being diverted by an external circuit as it switches from Bulk mode (constant current ) to Float mode based only on the battery terminal voltage.
However, a 2-Stage charger cannot completely charge the battery when the charger switches from bulk mode to float mode. After switching to float mode, the battery will, in most cases, be about 80% recharged. The battery receives the remaining recharge while in float mode over several days.
It is highly recommended to switch back to the 3 Stage Charger Mode periodically when the external load is disconnected.
Also the external load should not be more than 50% of the max. current of the charger , unless the battery is fully charged up . If the bulk LED is on most of the time then the load is too large.
G1. As a stand alone power supply
It can also be used as a stand alone power supply without connection to a battery
It will provide a constant voltage according to the selected Float Voltage (26.4/27.0/27.6V) and rated DC current of the charger.
However, it is not recommended for high surge load (such as lamp) in stand alone application as the initial high surge current will trigger the overload protection of the power supply.
Fig.4 Power Supply / 2 Stage Charger Mode Application
H. Temperature Sensor
The temperature sensor is available as an optional accessory (ATS-5120) and is used to optimal charging over wide ambient temperature range.
Fix the temperature sensor in a position on the battery which is not affected by other cooling or heating source.
Plug in the temperature sensor before switch on the charger to activate the temperature control function, never plug in the charger during charging.
