This small black connector on the back of the unit allows you to run less costly 3-conductor wire to your battery location instead of large heavy battery cables. Once at the battery location the 3-phase AC is fed into our AC Connection Kit (sold separately on our website) and converted to DC for connection to the battery. WindBluePower dot com   This PMA features the following: Completely Brushless design eliminates the need for maintenance and reduces friction. Note:  WindBlue AC output equipped alternators can still be connected for DC output by using the battery terminal on the back of alternator, however, only one output should be connected to your batteries at a time. The other should be left unconnected.  The 3-phase AC output connector DOES NOT make your alternator a “Grid-Tie” unit so don’t try to wire the AC leads into the fuse box of your house as death, fire, and destruction will likely result !! Specially wound High-Output stator. Super Strong  N42 grade Neodymium rare earth magnets are at its core to replace the inefficient electromagnetic field coil. Zero Cogging It is built using Brand New GM Delco alternator components including Stator Coils, factory balanced shafts and New Rotor Pole Shoes. Replacement bearings and parts will be available for years. Built-in rectifier. (DC output is unregulated) This unit can be used in a direct drive wind turbine, hydro-electric application. Built to last with new bearings and a baked on clear ceramic finish that will last for years in harsh outdoor environments. 90 day full replacement warranty on all units  (Warranty void if PMA has been opened or tampered with) Produces 12 Volts at just 275 RPMs and the voltage keeps going up from there. (see chart below). Produces 25 Amps into a 12 Volt battery at 2000 RPMs. Click here to check out our Frequently Asked Questions: FAQ page. The chart below represents actual output on a test stand. Voltage readings were recorded with the circuit open (No Load) while Amperage was recorded with the output shorted (Max Load). Your system setup will determine what output you will see in the “real world”.  For example a dead battery will pull much more current similar to the shorted output reading than will a fully charged battery. Also the voltage will rise until it meets the voltage of your battery and then level off as the battery is “absorbing” the excess voltage as it charges. This unit can handle over 10,000 RPM with ease but since the output is unregulated you should be sure and run a 30 or 40 amp fuse on the output to prevent damage to the unit if your load becomes excessive. Also consider using a charge regulator so your batteries don’t become overcharged. On our test stand with a 12 Volt battery connected the PMA produced 25 Amps at 2000 RPM.       For use as a direct drive wind generator, select a fast set of blades and you should start charging a 12 volt battery setup in about 12 mph winds. This unit passes the 12 volt mark at just 275 RPMs. The “Cy-Clone” rotor from TLGwindpower is a good choice. We are an authorized TLG dealer and have had great results with their designs. Many other websites offer good rotor designs and even plans for rotors if you would like to build your own, just make sure it has a 17mm hub to fit a standard Delco alternator shaft.    Proudly made in the USA Payment: I accept PayPal, Money Orders, Personal Checks, and Cashiers Checks.
