Solar Converters EQ 12/24-50, 50 amp DC to DC Voltage Converter Application This unit is an up or down voltage converter whose output is proportional to its input. It functions both ways, producing 12 V @ 50 Amps from a 24 V input or can be connected backwards to produce 24 V @ 25 Amps from a 12 V input.When connected across a 24 V battery, it functions as a battery equalizer, allowing loads to be taken off of the 12 V battery section of a 24 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 4 enclosure Simple to use Electrical Specifications Input high side Input Voltage (nominal battery) 12V 24V Output Voltage 24V 12V Output Current 25A Current Limited 50A Current Limited Ripple at load 30mV rms 30mV rms Efficiency 96% 96% Mechanical Specifications Enclosure: Weatherproof, NEMA 4 enclosure Dimensions: 12" X 10" X 4" nominal Temperature Range: -40 deg C to 60 deg C (It is recommended, as with all electronics, that the unit not be placed in direct sunshine) Terminations: #6 AWG Eurostyle Terminal Strip: High, Common, Low Humidity: Rainproof
