The technical conditions: - The output voltage :12V - between the wire resistance 10.5 ± 0.5Ω - Insulation resistance 10MΩ (DC100 megger ) - the maximum pressure 0.6Mpa outlet closed - the outlet opening maximum pressure 1.2Mpa - Start pressure 0.05Mpa The mechanical properties and the operating environment: - Appearance: generator surface clean , no rust, no scratches when significant , solid structure . - axial clearance 0.2-1.0mm - mechanical noise ≤55dB - the amount of the Generator : 90g around - generator life : ≥3000h Package Include: 1 x DC 12V DC generator 10W micro-hydro water turbine generator water F LED lights Rugged and Durable Material: The miniature hydraulic charging tool is made of durable material and strong structure. At the same time, it has a smooth surface, no rust, no obvious scratches, and the generator life is ≥3000h. Multi-Function Generator: The generator is suitable for a variety of electrical appliances and can directly charge small batteries. With a maximum charging current of 220mA. It can give you electricity protection in the event of a power outage. Output Efficiency: There is no voltage regulator inside this micro hydroelectric generator, direct output, the maximum output is 80v. The output voltage of the non-voltage regulator is proportional to the water pressure. Low Noise: The mechanical noise of our turbine generators is ≤55dB, low noise, and stable working performance. Even if you need to add electricity at work, rest or in a quiet environment, its work noise will not disturb you, allowing you to concentrate on your own affairs. Easy to Use and Store: The DC water pump turbine is small in size, light in weight, and easy to install, which means you can use it whenever you need it to provide you with power supply.
