Power Master PMDBC 3012 30A/12V Battery Charger

Power Master Digital Battery Charger, or DBC in short, is a smart and light weighted battery charger with unique LCD & LED Displays to allow users to read all information while charging, and to adjust charging current, charging time, etc. With this smart battery charger, dual output and pulse charge are also available with larger power models. To prolong battery lifespan, protections, pre-charge, and automatic multi-rate charging functions are specially designed for this purpose.
Using DBC series battery chargers can save more than 25% of main power cost, and in addition to protect your batteries and to extend lifespan of batteries.

Product Description


Unique LCD (digital meter) Display
 • For all models except 2Amp(12Vdc), 6Amp(12Vdc), 1Amp(24Vdc), and 4Amp(24Vdc), a unique LCD Display is attached for indicating both status of the charger and battery level, voltage, current and capacity. This further extends the function of a battery charger as it is now more intelligent and more user-friendly. Adjustments for charging current and charging time are possible.
LED Display
 • Clear and easy to understand LED Displays: Red (power), Green (floating charge), Orange (equalizer charge).
Automatic Multi-Rate Charging Function
 • The DBC chargers are able to detect the rate of current needed during charging and enable pre-charge, equalizer charge, or floating charge accordingly.
Dual Output
 • For models with 25Amp(12Vdc), 14Amp(24Vdc), 9Amp(36Vdc), 7Amp(48Vdc) and above, dual output is designed for connecting to two battery banks and charging both batteries at the same time. Each output has one rectifier to prevent countercurrent from happening. Ideally, the two battery banks should have same battery capacity, else the unbalance in different capacities may cause over charging.
Pulse charge
 • For models with 45Amp(12Vdc), 23Amp(24Vdc), 15Amp(36Vdc), 11Amp(48Vdc) and above, this function is available to fully charge the batteries and to increase the charging efficiency. For all other models except 2Amp(12Vdc), 6Amp(12Vdc), 1Amp(24Vdc), and 4Amp(24Vdc), pulse charge at beginning can be added for 12V and 24V upon request.
 • 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.
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.

Exquisite case design
 • The aluminum housing makes the charger to have best thermally conductive performance with modern case design.
