Descriptions: Perfect for energy conversion of the water into electrical energy mechanical equipment. Directly used to charge small battery, mobile phone, or power supply for LED lights, etc. Output characteristics: output voltage without the voltage regulator circuit is proportional to the water pressure. Installation: standard household 1/2 inch water pipe (outer diameter: 20mm, inner diameter: 13mm). F50-80V: DC 0-80V output, the generator does not have a voltage regulator circuit, the voltage reaches 80V, you can directly 3-12V 10W LED lights, you can directly charge the small battery, the charging current is about 220mA, because when charging The generated electricity is used up in a timely manner, so the voltage will be automatically kept at about 14V, and maintain a suitable voltage so that all the electricity is used to charge the small battery. F50-5V: DC 5V regulated output, you can charge your mobile phone or lithium battery with charge management chip. F50-12V: DC 12V regulated output, can supply power to 12V radio, charge, power LED lights. Specifications: Material: plastic+stainless steel Color: transparent+yellow Voltage: 5V, 12V, 0-80V Size: about 88x39x58mm Output voltage: AC 0-20V Output current: 0-150MA Flow range: 3-18L/m Pressure range: 0.15-0.8MPA output current: 220mA (12V) Line resistance: 10.50.5 Insulation resistance: 10M (DC100 megohmmeter) pressure of closed outlet: 0.6Mpa pressure of outlet opening: 1.2Mpa Starting water pressure: 0.05Mpa Axial clearance: 0.2-1.0mm Mechanical noise: 55dB Single generator: around 90g Package Included: 1pc x generator
