DC Hydroelectric Micro Generator Overview A compact DC hydroelectric generator designed to convert water flow into usable DC power for lighting and small electronics. Available in three output configurations: unregulated 080V, regulated 5V, and regulated 12V. Built for easy installation on faucets, shower heads, and similar water outlets where a lowstart water pressure is required. Key benefits Generates DC power from water flow without an external power source, allowing local power for lights, sensors, or small chargers. Starts at very low water pressure, enabling use with ordinary household faucets and showers. Robust materials and design increase durability and reduce maintenance needs. Multiple output options cover direct charging of small batteries and LEDs or regulated charging of USB devices and 12V loads. Main features Fourpoint external thread for water inlet and outlet, outer diameter approximately 20 mm. Stainless steel machine wire screws for improved durability. Low water pressure start: initial operating pressure 0.05 MPa. Hydroelectric separation technology combined with a clutch and dual magnetic circuits for safe separation of water and electricity. Enlarged vortex impeller and added bearings to improve generation efficiency and reduce wear. Strong Chinironboron magnets to enhance power generation capability. Fully sealed housing for simple installation and low maintenance. Electrical specifications Peak output voltage: up to 80 V at 1.2 MPa (unregulated model). Maximum output current: 100 mA at 12 V (regulated 12 V model). Unregulated current range: up to approximately 0220 mA depending on water pressure and load. Linetoline resistance: 10.5 ± 0.5 ohm. Insulation resistance: 10 megohm (measured at DC100). Terminal: 2 pin. Pressure and flow limits Initial start pressure: 0.05 MPa. Maximum closed water outlet pressure: 0.6 MPa. Maximum opening pressure of water outlet: 1.2 MPa. Model and output types 080V unregulated: DC 080 V output without voltage regulator. Peak voltage up to 80 V. Can directly drive 312 V 10 W LED lights and charge small batteries. Maximum charging current can reach about 220 mA under higher water pressure. Output voltage and current vary with water pressure. 5V regulated: stable DC 5 V output suitable for charging mobile phones and lithium batteries with appropriate charge management. 12V regulated: stable DC 12 V output for powering and charging 12 V radios and LED lighting. Mechanical and durability data Appearance: clean surface, no rust, no visible scratches, solid structure. Axial clearance: 0.21.0 mm. Mechanical noise: approximately 55 dB. Unit weight: about 90 g. Rated generator life: approximately 3000 hours. Mounting base included; installation is selfcontained. Package options Type A: 080V yellow water phase generator without voltage stabilizer x1 Type B: 5V yellow water phase generator with stabilized voltage x1 Type C: 12V yellow water phase generator with voltage stabilizer x1 Type D: 080V black water phase generator without voltage regulator x1 Type E: 5V black water phase generator with voltage regulator x1 Type F: 12V black water phase generator with voltage stabilizer x1 Typical applications and scenarios Faucet or shower lighting: install on a thermostatic shower head or faucet to power LED lights while water is flowing; use the unregulated 080V model for direct LED drive or the 12V regulated model for standard LED modules. Smart or induction faucets: supply local DC power to sensor circuits or lowpower control electronics where mains power is not available. Mobile charging and small electronics: use the 5V regulated model to charge phones or power USB devices when water flow is available; 12V regulated model can charge small 12V batteries or run portable radios and lighting. Installation and operation notes The generator requires compatibility with a fourpoint external thread of about 20 mm outer diameter; confirm thread match before installation. For the unregulated 080V model, output voltage and current vary directly with water pressure and load. No internal voltage regulation is provided. For regulated 5V and 12V models, stable DC outputs are provided for compatible loads. Performance depends on water pressure and flow. Initial start pressure is 0.05 MPa and maximum safe operating opening pressure is 1.2 MPa. Ensure correct mechanical alignment and secure mounting to maintain axial clearance and reduce noise and wear. This product provides a compact, mechanical solution for onsite DC power generation from water flow for lighting and small electronic loads.
