To Your

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.

Powering the Canadian Wilderness

Installation is just the beginning. Sentrex's forjlive brand is our in-house solution for remote monitoring and control. Forj monitoring interface will monitor your remote power supply and email reports with vital information to ensure your measurement campaign will have the power it needs. Remote telemetry can be configured for either satellite or cell phone communications and allow for pre-emptive troubleshooting to minimize service calls and indicate potential service required. Local field service is also provided by personnel fully trained on the design and deployment of these specific power supplies.
