These high-efficiency DC to DC converters can be used to step-up or step-down battery voltage. These converters are bi-directional so they can be used to increase or decrease voltage. They can be used to operate 12 volt loads on a 24 or 48 volt battery system or to run a 24 volt refrigerator on a 48 volt battery system. See the chart below for up and down voltage and current limits.

1-year warranty.

This device allows you to power 12 volt and 24 volt loads from a 24 volt battery system without unbalancing the voltage in part of the battery bank. Without this device, if you draw 12 volt from part of a 24 volt battery bank, and charge the bank with a 24 volt charging system, the half of the bank that the 12 volt loads are not connected to will always be at a higher state of charge.

This device allows you to draw 12 volts from the "lower half" of the bank while continuously recharging the "lower half" from the upper half. It automatically stops charging when the upper and lower half are at equal voltages.

The 60-20A amp version can maintain even battery voltage with up to 20 amps of draw on 12 volt circiuts.

The 65-60A allows the battery to supply up to 60 amps at 12 volts continuously. Inverters or other loads that are intermittently larger than the equalizer’s capacity can be used as long as the average amp draw over time is less than the capacity of the device.

These DC-DC converters are designed to decrease, the DC voltage that is input to the unit. These switching converters have a high efficiency and provide regulated 13.8 VDC output from and input of 20 -30 VDC.

Use them to power 12 volt lights and appliances from a 24 volt system.

The Smart Adapter is a high efficiency DC to DC converter that converts the the 12 volt output from a car lighter socket to the voltage required to charge many brands of notebook computer battery or a cell phone, or power a device with a co-ax power jack that can operate on 30 watts or less at 6 to 19 volts.

It can be used to power and charge small notebook computers, PDA’s and phones directly from a car cigarette lighter socket. Output voltage is adjustable from 6 to 19 volts.

Choose one of the three enclosed coaxial ends included or purchase a specialty plug from an electronics supplier.
