Converts from 12 Volt 4 Amp to 6 Volt 8 Amp. The features are 1. Synchronous rectification technology, the conversion efficiency more than 96%. 2. Internal resistance capacitor filter, withstand high temperature. 3. Almost no heat generated when operated. 4. Chip smart protection, anti-overheating, overcurrent protection. Use this to power your 6 volt powered devices from 12 Volts. Works both positive ground and negative ground vehicles, motorcycles and scooters. It is a good ideas also to put a power switch to turn off the device when not in use. It could be wired to your ignition line where power would be applied when the ignition switch is turned on. Operates from 10V to 35V input voltage. The output is regulated at .1V@6V. The output power is 48 Watts. The Transfer efficiency up to 96%. The Working temperature is -25℃-85℃. The converter has overheating protection at 150℃. The no load current ≤0.35mA. The no load current is why you want to connect to your ignition line or add a power switch to turn off when not is use. The converter is water proof IP68 rating. The weight is approximately 0.1kg. The approximate size is (L)64*(W)57*(H)22mm which is (L)2.51"x(W)2.24"x(H)0.87". The wires length is 15cm or 5.9". The input 10-35 Volt wires are red+ and black ground. The output wires are yellow +6 8A and black ground. The hole to hole center is 52mm or 2.04". The hole size is 5mm or .19" diameter. Some of the applications are for: Motor, audio, navigation, monitoring, LED display, air conditioning, electric fans, solar energy, photovoltaic energy, DVD lights, motors, pumps and industrial equipment.
