Application

This unit is an up or down voltage converter whose output is proportional to its input. It functions both ways, producing 12 V @ 30 Amps from a 48 V input or can be connected backwards to produce 48 V @ 7.5 Amps from a 12 V input.

Also, regulated models are available to produce a fixed output voltage instead of the proprotional output. For example, Model EQ 12/48-25 R13.5 produces a fixed 13.5 V output at 40 amps from a 48 V nominal battery source.

When connected across a 48 V battery, it functions as a battery equalizer, allowing loads to be taken off of the 12 V battery section of a 48 V battery pack without fear of damage to the battery pack due to voltage mismatch.

Features

• >94 % efficiency, typically 93 % over 20 % load
• Bi-directional power flow
• Weatherproof, NEMA 3R enclosure
• Simple to use

Voltage Regulation Mode

This standard unit regulates the output voltage proportional to 1/4 the input when connected 48 V input and regulates the output to 4 X input when connected 12 V input. This characteristic, when connected across 4 X 12 V batteries in a 48 V configuration, will keep the batteries at equal voltages.

Special units are available for example EQ 12/48-30 RXX where XX is the voltage on the 12 V side that the voltage is to be regulated to. For example, EQ 12/48-30 R13.6 will output 13.6 V @ 30 amps to either power a 12 V load or charge a 12 V battery to 13.6 V.
