Application

This rugged and versatile unit is used to power a small load at 12 V from a 24 V battery, or to power a small 24 V load from a 12 V battery.
It functions both ways, producing 12 V @ 2 Amps from a 24 V input or can be connected backwards to produce 24 V @ 1 Amps from a 12 V input.

When connected as a battery equalizer, it allows large transient 12 V loads to be taken off the centre tap of a 24 V battery (made of 2 X 12 V batteries) without fear of upsetting the voltage balance of the battery and destroying the 24 V battery system that would otherwise occur.

Features

• 95 % efficiency, typically 96 % over 20 % load
• Bi-directional power flow
• Simple to use
• Weatherproof, NEMA 4 enclosure

Electrical Specifications

Voltage Regulation Mode

This standard unit regulates the output voltage proportional to 1/2 the input when connected 24 V input and regulates the output to 2 X input when connected 12 V input. This characteristic, when connected across 2 X 12 V batteries in a 24 V configuration, will keep the batteries at equal voltages.

Special units are available for example, EQ 12/24-2 RXX where XX is the voltage on the 12 V side that the voltage is to be regulated to. For example, EQ 12/24-2 R13.6 will output 13.6 V @ 2 amps to either power a 12 V load or charge a 12 V battery to 13.6 V.
