Remote Power Supplies

Sentrex Wind Services' power supply was developed over many years and is the most reliable power supply in the industry today.

Suited

To Your

Our fully automated remote power supplies are specifically designed for reliable operation in remote sites and have been proven in the harshest conditions Canada can deliver. Heavy-duty enclosures ensure that events such as heavy ice build-up, wildlife ingress and adverse weather conditions do not affect power delivery to essential loads. By using solar power when available, use of the backup power is minimized and the time between service calls can be increased significantly.

All units are fully built at our Canadian headquarters, tested and operated for 24hrs in our custom-designed cold climate chamber. After the quality control phase, the units are then installed at your site and commissioned on arrival.

Sentrex offers purchase and full-service LiDAR and SoDAR rental options on our fully automated remote power supplies.
