DC 12V Water Turbine Generator – Mini Hydro Generator

Product Description

The DC 12V Water Turbine Generator is a compact micro hydro generator designed to convert the energy of flowing or pressurized water into electrical power. It combines a small water turbine with an integrated generator, allowing water movement through the unit to rotate the internal turbine and produce DC electrical output. This makes it useful for educational projects, DIY renewable-energy experiments, small off-grid systems, and low-power applications where a continuous water source is available.

The generator is designed for a nominal 12V DC output and can provide up to approximately 200mA under suitable operating conditions. Actual output depends strongly on the available water pressure and flow rate. For the unregulated version, the generated voltage varies with water pressure, so a suitable voltage regulator or charge-control circuit may be required when connecting sensitive electronics or rechargeable batteries.

A major advantage of this mini hydro generator is its low starting pressure. The turbine can begin generating at approximately 0.05MPa, making it suitable for installations using pressurized water lines and small-scale water-flow experiments. Its compact construction also makes it easy to integrate into custom mechanical and electrical projects without requiring a large turbine system.

The unit uses a water-isolated generator design and has a wire resistance of approximately 10.5Ω ±0.5Ω with an insulation resistance of around 10MΩ. The mechanical construction provides an axial clearance of approximately 0.2–1.0mm, while operating noise is specified at no more than approximately 55dB.

The turbine is suitable for applications such as powering low-power LED lighting, demonstrating hydroelectric power generation, supplying small DC loads, and providing energy for experimental battery-charging systems. When used for battery charging, an appropriate charge-management circuit should be installed rather than connecting the generator directly to a battery.

With a lightweight generator body of approximately 90g and a stated service life of 3000 hours or more, this mini hydro generator provides a practical platform for exploring water-powered electrical generation in compact systems.
