DC Converter EQ 12/48 Cat No: 658SELDEQ124810

Solar Converter DC Converter EQ 12/48-10 Amp and 30 amp Used to keep your load voltage constant at 48 V as the battery discharges from 14 to 11 V. This rugged and versatile unit is used to power a small load at 12 V from a 48 V battery, or to power a small 48 V load from a 12 V battery. It functions both ways, producing 12 V @ 10 Amps from a 48 V input or can be connected backwards to produce 48 V @ 2.5 Amps from a 12 V input. When connected as a battery equalizer, it allows large transient 12 V loads to be taken off the first tap of a 48 V battery (made of 4 X 12 V batteries) without fear of upsetting the voltage balance of the battery and destroying the 48 V battery system that would otherwise occur.

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.
