Description

Technical Specs

NEW: Now all WindBlue DC-520 and DC-540 Alternators are equipped with a 3-phase AC Output pigtail. 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 a rectifier box (sold separately) and converted to DC for connection to the battery.

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.

WARNING: 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 !!

Great for 24 and 48 Volt setups.

The DC-540 Model is perfect for use as a wind generator in areas that experience average winds of 5-15 MPH. Reaches 12 Volts at 150 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 over 10,000 RPM with ease but since the output is unregulated you should be sure and run a 20 or 30 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 15 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 7 mph winds. This unit passes the 12 volt mark at just 150 RPMs. The �Cy-Clone� rotor from windbluepower.com is a good choice. 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.

This PMA unit features the following:

This PMA unit features the following:
Completely Brushless design eliminates the need for maintenance and reduces friction.
Specially wound Low RPM Output stator.
Super Strong N40 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 NEW 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 is perfect for direct drive wind turbines in areas that only see 5-15 Mph winds on average.
Great for 24 and 48 Volt setups.
Not recommended for motor driven or geared up wind use. Please select our DC512 model for use with engine driven applications and DC-520 for geared up wind use.
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)
Reaches 12 Volts output at just 150 RPMs and the voltage keeps going up from there. (see chart below). Makes over 350 Volts at 2500 RPM.
Produces 15 Amps into a 12 Volt battery at 2000 RPMs.

Very Good Product	August 28, 2008
Reviewer: Charles�Hastedt Sr. from Kemp,�TX�United States

I am very happy with the results of your Low Wind 540, after many months of experimenting on various ways to come up with the perfect 12 Volt charging system for low wind, I gave up and choose to try your 540. I took it from the box and went straight to my Volt tester. I couldn't believe the output by only turning it with my fingers, on the 15 volt scale I was getting a half scale reading of 7.5 volts. This is truly the setup for battery systems of any type, it does everything it is advertised to do and more. Thank you WindBlue for this product. (Very Good People To Deal With)
I also bought the NC25A 12V Controler that will work very nicely with my system to prevent battery overcharge.

hydro	August 23, 2008
Reviewer: roys�ellis from Waihee Valley, Maui, �HI�United States

Built a 40" water wheel utilizing the 300 gpm flow from the kuleana ditch to my taro loi. Disappointing at first with o less than 60 amphr output into a 12 volt battery bank over 24 hours. After running at 300 rpm for over two weeks, with the same output, output began to slowly rise over a months time to the present 85+ amphrs/day. Extended run in time for the unit, but excellent results.

great find, super quality.	March 12, 2007
Reviewer: David Rymer from marion, VA United States

I bought this for my area which is rated for low wind.This is my first wind generator.I made the blades my self, using pvc. I have had it up 2 days but we have only had 0-4 mph winds but it starts turning at 4mph.I cant wait for the first windy day to check out the amps.... I feel I will have great results. All my friends are watching and soon will order one too.
