Introduction

This unit is an up or down voltage converter whose output is proportional to its input. It functions both ways, producing 24 V @ 30 Amps from a 48 V input or can be connected backwards to produce 48 V @ 15 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 24/48-25 R27 produces a fixed 27 V output at 30 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 24 V battery section of a 48 V battery pack without fear of damage to the battery pack due to voltage mismatch.

Features

• >95 % efficiency, typically 96 % 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 1/2 the input when connected 48 V input and regulates the output to 2 X input when connected 24 V input. This characteristic, when connected across 2 X 24 V batteries in a 48 V configuration, will keep the batteries at equal voltages.

Special units are available for example EQ 24/48-30 RXX where XX is the voltage on the 24 V side that the voltage is to be regulated to. For example, EQ 24/48-30 R27 will output 27 V @ 30 amps to either power a 24 V load or charge a 24 V battery to 27 V.
