6. Pre-charge
When batteries are over discharged, bulk charging could damage the batteries. In order to
prevent this from happening, pre-charge function will be initiated automatically once the charger
detects battery voltage under 10V. When start charging, the charging current is limited to 50%
and pre-charge timer will start counting for 30 minutes. If the battery voltage increases to above
11.5V within 30 minutes, the charging current will return to 100% again.
This function is available for models
12Vdc: 10A~30Amp 24Vdc: 7A~17Amp 36Vdc: 4A~11Amp 48Vdc: 3A~8Amp
7. Cooling fan controlled by floating voltage
When reaching to floating stage, rotating speed of the fan will slow down or the fan will stop in
order to increase lifespan of fan. During bulk charging, the fan will rotate in fast speed to
lowering the temperature.
With 2Amp(12Vdc), 6Amp(12Vdc), 1Amp(24Vdc), and 4Amp(24Vdc) models, cooling fans are
controlled by temperature instead of floating voltage.
8. Exquisite case design
The aluminum housing makes the charger to have best thermally conductive performance with
modern case design.
9. Adapted to each battery technology
Chargeable for Lead-Acid Battery (liquid electrolyte, gel electrolyte, lead calcium, etc…)
DBC for Lithium Battery, please contact sales persons individually.
Protections
1. Short-circuit Protection
The charger output will cut-off automatically when short circuit.
2. Overload protection
The charger output current is limited automatically when overload.
3. Reverse polarity protection
The charger output will cut-off automatically when batteries are in reverse connection. Models of
30Amp(12Vdc), 17Amp(24Vdc), 11Amp(36Vdc), 8Amp(48Vdc) and above are protected by fuse;
all other models are protected by circuit.
4. Over charge protection
Using fixed voltage and limited current to avoid overcharging the batteries
5. Temperature protection
If the temperature of environment or the case of battery charger is too high (around 65 ~75 ),
℃ ℃
the unit will adjust the current automatically to protect battery charger and batteries.
