The DC-512 model is best suited for motor driven applications or very high wind locations when used in a wind generator setup. Reaches 12 Volts at 650 RPM 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 up to 10,000 RPM. The output is unregulated. You should be sure and run a 40 or 50 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 40 Amps at

2000 RPM.

 

 

 

Shaft Threads are 5/8 x 18 tpi

 

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 15 mph winds. This unit passes the 12 volt mark at just 650 RPMs. The “Cy-Clone” rotor from can work but a better choice would be the 7' Foot Elite rotor from TLGWindpower.com and design a gear up system.  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.
