Waterproof IP68 Voltage Converter Regulator DC 12V to DC 48V 2A 96W. Protections: Over-load, Over-current, Over-temperature, Short-circuit, Over-voltage. Auto-recovery when device is back to normal operating; high transfer efficiency of 95% max. Die-cast aluminum shell, anti-shock, moisture-proof, and with enhanced durability. Widely used in solar power generation, as well as in display screens for buses and taxis. It is recommended to use stable DC power for the input supply. If utilizing pulsed DC power from a generator, please filter it with a capacitor before connecting it to the converter. When using a solar panel for direct supply, ensure the open circuit voltage of the panel does not exceed the converter's maximum withstand voltage. The supply voltage should remain within the rated voltage and always allow for a certain margin. Size: 4.72 x 4.13 x 1.77 inches.
