WTAPRS: Tough Wind Turbines ... for a Tough World

APRS World's WT10 micro wind turbine is the premiere wind generator for extreme wind enviroments. We have spent years developing and testing the WT10 in downright brutal locations and applications. Regular 150+ MPH winds, ice, and lightning. Every component of the WT10 has been repeatedly revised to make it as tough as possible and work in the most demanding enviroments. Simply put, there isn't a tougher micro wind turbine on the market.

Besides the WT10 wind turbine, we manufacture turbine control panels, output cables, dump loads, tower components, specialized installation tools, and even highly innovative mounting structures for ISO shipping containers. With our years of experience in data acquisiton and control systems for small wind, we can offer both the most advanced and the most cost effective instrumentational, control, or telemetry systems.

GL Boom

Mounting Options for APRS World Sensors

APRS World, LLC offers sensor mounting booms in a variety of shapes and sizes. These can be customized to meet our customers needs, so call us to discuss the best solution for your application.

Masts and towers are also available.



LED Light for DC Applications

A beautiful white LED light for 12, 24, and 48 volt DC applications. 3.5" diameter anodized aluminum and frosted glass body looks great in home and industrial applications alike. Perfect for under counter lighting, but also great for task and room lighting.



DL300: Dump Controller and Load

APRS World's DL300 series dump controller and load is an integrated solution designed to prevent 12 or 24 batteries from overcharging.

We also offer a 600 watt modular dump load.



APO3: Automatic Power Off Device

The APO3 is a black box designed to prevent a vehicle battery from being discharged and damaged by a DC load. Typically, it is used to switch a radio transceiver off 10 minutes after the vehicle is shut off. Ideal for use with mobile APRS stations, the APO3 allows the radio to transmit a few position reports after the vehicle is shut off and then it turns off the radio and GPS to reduce clutter on the APRS channel and prevent the vehicle battery from discharging.

XBee-PRO RF Modem

Modem Options for Communicating with APRS World Products

Digi International makes a wonderful line of 802.15.4 XBee modems. They are fast, powerful, and reliable short range modems. The only downside to the modems is that they aren't readily available, having a lead time of six weeks or more. Faced with a long lead time and a short-deadline project, APRS World designed our own external USB modem that uses a Digi XBee-PRO modem. This product is functionally similar to Digi's XBee-PRO PKG modem package. We also offer an RS-232 potted modem and an Xbee to Ethernet gateway.



Books: Learn about Wind Power

Our favorite books about wind power. For anyone who is interested in a wind project, these are required reads.
