Our fully automated SoDAR and LiDAR 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.

​Each of our units is fitted with a sound-dampened SoDAR or LiDAR compartment with propane heating to reduce the environmental effects on the data. RSD-equipped SoDAR and LiDAR Power Supplies trailers are validated against our IEC-compliant SoDAR and LiDAR validation tower to verify the full height range of remote sensing devices.

SoDAR and LiDAR rental options on our fully automated remote power supplies.

Sentrex power supply snow melting capabilities 2

To show the consistent Sentrex power supply melting capabilities, we allowed for another approx. 6in of snow to build up on the dishes of a AQ510 SoDAR in one of our power supplies. In 2 hours with the use of propane heaters, heat trace and dish heaters, the snow completely melted. Each transition is a 5min interval taken by the SoDAR barrel camera. These heating capabilities can be applied to any remote sensing device, be it a LiDAR or SoDAR, to improve the data availability during the winter months. Our fully automated power supplies are specifically designed for reliable operation in remote sites, and have been proven in the harshest conditions Canada can deliver. Using SoDAR or LiDAR technologies, paired with a Sentrex Power Supply, reliable meteorological data can be acquired.
