Power Sources
The DewBuster™ Controller may be operated on a 12V Battery or 13.8 VDC Power Supply (fully charged 12V batteries measure 13.8V). All DewBuster™ Controllers have a Low Voltage 10.5V cut-off to prevent running your battery completely dead and damaging it. The newest DewBuster™ Controllers also have a High Voltage 16V cut-off to protect your heaters from burning up if your power supply should malfunction and go to 24V.

As shown above, DewBuster™ Controllers with Powerpole® connectors can switch between different pigtails to fit various power sources. I highly recommend this option so that if you change power sources you will not have to send your DewBuster™ Controller in to have the power cord changed, you simply order a pigtail to fit your new power source. For more information see my FAQ on Power Cords.

If you need help selecting a battery see my FAQ on power sources. If you are considering a PowerTank, remember that it is just a "Jump-Start" battery with extra features. If you do not need the extra features, consider a conventional Jump-Start battery available at tool or auto parts stores at much better prices. When 120 VAC is available you can power the DewBuster™ Controller while the battery is on the charger so the battery does not run down yet it prevents loss of power if the AC power is momentarily lost (use a normal charge rate, do not "Fast Charge").

When purchasing a power supply consider the following:
