Solar Converter EQ 12/48-10, 10 amp DC to DC Voltage Converter Application 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. Features 95 % efficiency, typically 96 % over 20 % load Simple to use Bi-directional power flow Weatherproof, NEMA 4 enclosure Electrical Specifications Input high side Input Voltage (nominal battery) 12V 48V Output Voltage >48V 12V Output Current 2.5A Current Limited 10A Current Limited Ripple at load 30mV rms 30mV rms Efficiency 95% 95% Mechanical Specifications Enclosure: Weatherproof, NEMA 4 enclosure Dimensions: 4.5" X 2.5" X 2" nominal, resembling a junction box with feet Weight: approx. 2 lbs.
