Description
Highly accurate and robustly designed, this device is an ideal solution for managing professional equipment: it collects and monitors weather conditions while issuing timely alerts. This keeps you informed of wind speeds that could compromise the safety of people and property across a wide range of applications.
Equipped with the renowned Maximum #400 anemometer, the MAC3 can be configured to operate with two sensors simultaneously, allowing for the monitoring of two separate locations.
The MAC3 includes time-delay and interlocking (latching) functions to prevent equipment damage caused by overly frequent on/off cycles. It features a large, easy-to-read LCD screen (green text on a black background) that displays current wind conditions, configuration settings, and custom data—such as average wind speeds, peak gusts, and other key metrics.
The unit can be password-protected to prevent accidental changes to settings. Furthermore, its two 5-amp relays allow for the control (on/off switching) of external equipment—such as outdoor event installations, agricultural machinery, municipal fountains, construction equipment, cranes, security systems, awnings, automated gates, outdoor advertising displays, and various other types of equipment that could be affected by the wind or become hazardous during adverse weather conditions.
Features
- The Maximum MAC3 controller and anemometer are weatherproof (IP65-rated) and designed to operate within a temperature range of -40 to 70 °C (-40 to 158 °F).
- Compatible with 12-volt and 24-volt direct current (DC) power supplies, the controller measures 129.0 mm wide x 187.8 mm high x 57.4 mm deep (5.08 in x 7.39 in x 2.26 in).
Included with the system
- The MAC3 system comes complete with a wind speed sensor (model no. 400),
- a 100-foot (approx. 30.5 m) sensor cable,
- a 14-inch (approx. 35.6 cm) straight stainless steel mounting mast,
- and the necessary mounting hardware.
