Instruction and normal responses
Operation as booster charger
Connect the DC input terminal to the DC power source. Turn On
the Power switch, the “POWER ON” LED lights up. This indicates
the device is ready for charging. The “BULK” LED lights up. This
means the battery charger is beginning at the 1st stage of charging.
According to the battery type, adjust the charge setting dip switch
to get the optimum charge.
Connect battery to the DC output terminal. The smart booster
charger will perform the four stages charging automatically.
The 1st stage is to ensure battery is
always charged at the maximum
charging condition. This is to boost
up the charging cycle and particularly
wake up a weak battery to absorb
energy.
In about 10-20 mins, the charger will
switch to 2nd stage, the “BULK” LED
remains ON, the battery is charged at
the maximum charging voltage. The
voltage level can be adjusted by the
switch No. 1,2 and 3.
At the 3rd stage, the charger will switch to “ABSORPTION” mode,
the red LED goes out and the yellow LED lights up. The device is
delivering maximum current to the battery.
At the 4th stage, the battery has been charged to about 85% of its
rated capacity. The “ABSORPTION” LED goes out and the
“FLOAT” LED lights up. Battery is now under “FLOAT” constant
charging. The charging voltage can be adjusted by the switch No.
4 and 5.
Operation as power supply
The device can be used as a Power Supply. Set the switch No. 6
to ON position. The device now operates as a power supply unit.
The bulk and absorption LED goes out. Switch No. 1,2 and 3 are
now disabled. The POWER ON and FLOAT LED light up. The
output voltage can be adjusted by the switch No. 4 and No.5.
Note: When device is not in used for extended period, please disconnect from batteries
and supply. This device has a very small internal power consumption but will drain
a battery over a long period. (Approx 0.03A)
Introduction
This compact DC - DC Isolated 4 stages Booster charger uses
the latest switch-mode technology and is designed to meet all
modern automobile applications.
Galvanic isolated means you can connect to any load without
worrying about interference from the input to the output. The 4
stages Booster Charger is designed to charge Lead-acid
batteries to its best status, thanks to the first stage, this helps
activate the battery status and wake up a weak or flat battery to a
suitable recharging level. This improves the battery life and in
turn helps to save the environment.
Since the DC supply from a vehicle’s generator is often unstable
and this will shorten the life of an electronic device. This DC-DC
isolated booster charger can be used as a constant power supply
to run accessories that require a stable and clean DC voltage.
For example: LCD TV, Digital Hi-Fi system, Wireless telephone
systems, refrigeration systems, LED lighting, games, mobile
computer and more....
The booster charger is designed with auto power on/off features.
It will auto start-up if the input voltage is above 12.5VDC . To
protect from high voltage charging, it will auto cut-off if the input
voltage is over 21VDC.
The booster charger is designed with overload and short circuit
protection. It will automatically switch off the unit and re-start if
the overload or short circuit problem is corrected.
The cooling fan is thermal controlled. It will switch on and off
automatically to control the internal temperature of the unit.
Remote on/off controls
The external lead wire on the rear panel is used for remote
switching with on-board voltage (e.g. ignition from the vehicle
engine or external switch). Note: The device power on/off switch
must be switched off after the external lead wire is connected.
CAUTION!
To prevent malfunction of the device, keep the external lead wire
insulated if it is not in use.
