12Vdc, 28 Watts max

 

Now you can experiment with micro hydroelectric power without spending a lot of money.  A residential hose spigot will NOT normally produce the necessary pressure and flow to operate this unit.  However, if your home water service is supplied through a 3/4" line you can install a 3/4" tee close to the the service entrance with a 3/4" valve and this usually WILL be sufficient to operate this turbine.

Will produce up to 28 Watts 1.9 Amps maximum output at a nominal 12Vdc or 40 Watts 1.6 Amps at 24Vdc.  Water source must be 35 psi head pressure at inlet with 12 gpm available to achieve maximum output.  Includes a permanent magnet dc generator (motor) with long life replaceable brushes.  Impeller is magnetically coupled which means there are no seals to wear out and replace.  Impeller housing is long lasting bronze.

This mini micro hydroelectric generator can be used for battery charging.  Or, with our optional diversion load/regulator it is a source for a stand-alone dc system WITHOUT a battery that can be used to power small electrical loads like LED lights or dc compact fluorescent lamps.  Perfect for that remote cabin or even a rural off-grid cottage.

The optional meter package includes 0-30V Voltmeter, 0-3A Ammeter, wiring, terminals, connection diagrams, mounting bracket and hardware.  The meters are analog 5% accuracy.

The optional regulator/diversion load is a solid state device that controls the output voltage by diverting excess power to the heat sink.  Power rating is 50 Watts.  The specially designed meter mounting bracket acts as heat sink and is cooled by the turbine.  The regulator is designed to be used WITHOUT a battery bank and will maintain the Voltage to within +10% of nominal.  Must be ordered as 12V or 24V and requires the meter package.  The meter/regulator packages will start shipping in mid-March 2011.

California Law, Bill #1953, states that any item which provides water for human consumption shall contain no more than 0.2% lead.  Therefore, the bronze housing should not be used to supply potable water systems.  Order the alternative plastic housing below for such applications.
