100W Wind Generator Ampair 100 Wind Turbine - A complete wind turbine system for land or marine use The Ampair 100 wind turbine has an unrivalled pedigree as the microwind turbine of choice for absolute reliability for charging battery systems in harsh conditions. Although it only generates up to 100 watts of electrical power in practice it often outperforms so-called 400 watt machines because of its very good low
wind speed performance. Startup wind speed is only 7 mph. Technical Specifications Performance Up to 100 watts of power is developed by the permanent magnet alternator. The design allows the charging of totally flat batteries and prevents reverse current flow due to internal rectifiers. The machine has no commutator brushes to wear out and cannot overheat. It requires no thermal
cut-outs or other forms of control to safeguard generator & protect windings from burn-out. Slip rings and brush gear allow the wind turbine generator to seek the wind and feed two wires connecting directly to the battery. Power output With the Ampair 100 the output is continuously available. The maximum current automatically flattens out at a safe value, due to self-inductance of the heavy duty windings. Similar sized machines, with low inductance and light duty windings, have to be protected against burnout by the use of temperature activated cut-out switches which interrupt charging. CHECK performance figures of alternative machines which only give best case figures while concealing reduced average output when machine is in cut-out mode. Ampair current (Amps) values are continuous. DC cable length and voltage drop
must be evaluated carefully when laying out system. Click here for our simple
voltage drop calculator. Reliability A highly reliable microwind turbine is especially important for unattended and remote installations. In the Ampair 100 this is achieved by the extreme simplicity of the direct drive alternator and total sealing of internal electrical and mechanical parts. It is built to professional standards and easily outlasts cheap and lightweight alternatives. Offers superior value for money. In ten years of coastal operation, an Ampair microwind generator does as many revolutions as the engine of a car on a one million mile journey! Materials, and low temperature operation Excellent corrosion resistance is achieved by the exclusive use of
aluminum alloy, stainless steel and plastic materials for all external parts, backed up by the comprehensive use of elastomer seals and topped off by a
baked white paint finish. Plastic materials do not perform well in extreme cold, becoming brittle and breaking. This applies to wind turbine blades, whether glass filled or not. Operation at around zero Centigrade should not be a problem, but most materials are vulnerable at -20C and cannot be warranted to survive. The Ampair 100 uses glass filled polypropylene blades,
molded with large sized fibers in a compression process, which are superior to nylon, carbon polymer or other plastics in this respect. However, when icing is also considered, the prediction of blade reliability is even more difficult. Other materials are also suspect. Examples are Nitrile used in exposed seals and 0-rings and basic PVC cable sheathing. For this reason Ampair uses Neoprene components where possible. Grease used in sealed bearings allows performance to -30C or below, but component tolerances (ball and ring) can lead to greater friction and increased wear causing reduced bearing life. If desired Ampair can quote for special components to operate in Arctic/Antarctic conditions. Maintenance and Recommended Spare Parts The Ampair 100 is designed so that users can strip it down
in the field and replace those components that wear out over time or that become damaged in accidents. In remote locations or on long sailing voyages accidental damage is always a possibility. We suggest that two spare wind turbine blades be carried. Other spares to consider are: Pivot Seal, Shaft Seal, Set of Brushes and Caps.
Recommended short-term and long-term spare parts are listed below. Mounting options Ampair manufactures a range of mountings for the Ampair 100. Some are only intended for use on boats, some are only intended for use on land, and some can be employed in both situations.

12Vdc, 24Vdc, 48Vdc
Land/Marine Version
* Generates up to 100 Watts for 12 Volt, 24 Volt or 48 Volt battery systems.
* Designed to survive the severe marine environment.
* Heavy duty, all-weather generator, sealed to keep corrosion out.
* Permanent installation as a fit & forget unit.
* Found in many other applications such as weekend chalets, radio repeaters, navigation equipment or anywhere
that requires 12v/24v battery charging.
* Save the cost of fuel and the need to run noisy engines. Reduce engine running under light
loads.
* Supplement solar charger output with energy that is potentially available day and night; winter and summer.
* Improve battery condition and extend battery lifetime. Increase battery charging out of summer season when
electrical demand increases but sunlight reduces.
* The Ampair 100 frequently produces in a day what an equivalent costing solar array would take a week to
accumulate. The only penalty is the need to have a safe and secure mounting in as exposed a location as
possible .... but just think of all that ENERGY.
