Application

This rugged and versatile unit is used to power a small load at 24 V from a 48 V battery, or to power a small 48 V load from a 24 V battery.
It functions both ways, producing 24 V @ 10 Amps from a 48 V input or can be connected backwards to produce 48 V @ 5 Amps from a 24 V input.

When connected as a battery equalizer, it allows large transient 24 V loads to be taken off the centre tap of a 48 V battery (made of 2 X 24 V batteries) without fear of upsetting the voltage balance of the battery and destroying the 48 V battery system that would otherwise occur.

Electrical Specifications

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 24/48-10 RXX where XX is the voltage on the 24 V side that the voltage is to be regulated to. For example, EQ 24/48-10 R27 will output 27 V @ 10 Amps to either power a 24 V load or charge a 24 V battery to 27 V.
