F50 Series Water Flow Generators Compact microhydro generators designed to convert household water flow into usable electrical power. Available in three model options to match different applications and devices. Key benefits Converts water flow energy directly into electrical energy for onsite use. Simple installation into a standard household 1/2 inch water pipe (outer diameter 20 mm, inner diameter 13 mm). Multiple output options for different needs: regulated 5 V, regulated 12 V, or unregulated voltage DC up to 80 V. Lightweight and compact for easy mounting and low space requirement. Durable construction with plastic housing and stainless steel shaft for long service life. Model and output details F5080V: DC 0 to 80 V unregulated output. Peak voltage can reach 80 V. Can directly power 3 to 12 V 10 W LED lights and can directly charge small batteries. Typical peak charging current about 220 mA. When charging a small battery, the generator voltage will selfstabilize around 14 V as generated power is consumed. F505V: DC 5 V regulated output. Suitable for charging mobile phones or lithium batteries when used with a charge management chip. F5012V: DC 12 V regulated output. Can supply power to 12 V radios, charge 12 V batteries, and power 12 V LED lighting. Performance and specifications Material: plastic and stainless steel Shaft material: stainless steel Color: transparent and yellow Size: about 88 x 39 x 58 mm Weight: approximately 90 g per unit Measured AC output range: 0 to 20 V (modelspecific DC outputs as listed above) Output current: 0 to 150 mA (typical), peak output current 220 mA for the 12 V scenario Line resistance: 10.5 ± 0.5 ohm Insulation resistance: 10 M ohm (measured with DC 100 megohmmeter) Flow range: 3 to 18 L/min Operating pressure range: 0.15 to 0.8 MPa Starting water pressure: 0.05 MPa Peak closed outlet pressure: 0.6 MPa Peak outlet opening pressure: 1.2 MPa Axial clearance: 0.2 to 1.0 mm Mechanical noise: about 55 dB Installation and use Designed for selfcontained installation into a standard 1/2 inch household water pipe (OD 20 mm, ID 13 mm). No external drive source required. Output behavior: for unregulated models, output voltage is proportional to water pressure and flow. Regulated models maintain their rated DC output suitable for direct device charging. Typical operation produces small currents suitable for battery charging, LED lighting, or lowpower electronics. Practical applications Offgrid LED lighting: install the F5012V in a water line feeding a garden tap to power or charge 12 V LED lights when water flows. Small battery charging: use F5080V to charge small leadacid or similar batteries while water is running; the charging current can peak near 220 mA and the system will stabilize voltage during active charging. Mobile device charging at remote sites: use F505V combined with a charge management circuit to provide regulated 5 V charging for phones or USBpowered devices where flowing water is available. Notes Color may vary slightly from images due to lighting. Allow 0.5 to 2 cm tolerance for manual measurements. This product is intended for converting water flow into lowpower electrical output for small devices and batteries. Follow appropriate electrical and plumbing practices when installing and using the generator.
