Combining a retractable winch, integrated tether cable, and a ground power box with an 800-1000 V DC output, the AF-G15-100M enables extended flight endurance, robust telemetry and data links, and safer tether operations for industrial, public-safety, and event applications.

Key Specifications

Note: For exact weight, cable length and part numbers, consult the official product page or your supplier.

Features & Functionality

• Integrated retractable winch for smooth cable pay-out and retraction, minimizing tangles and drag.
• High-voltage DC delivery (800-1000 V) with 15 kW nominal power - supports power-hungry payloads and extended flight time.
• Wired data and telemetry channel to deliver stable video, control and sensor data with reduced RF interference risk.
• Torque control knob and control panel to set and maintain tether tension; voltage/current/power readouts for operator awareness.
• Durable system enclosure with fan cooling and user safety procedures for powering and reeling operations.

Benefits

• Extended operational time: Ground-supplied power eliminates reliance on onboard battery duration for many missions.
• Improved safety and stability: Controlled reeling and tension reduces cable hazards and ensures controlled descent and ascent.
• Reliable connectivity: Wired data link provides consistent telemetry and high-definition video without radio dropouts.
• Supports heavy payloads: High-voltage and high-power output enables operation of advanced sensors, communications gear, or heavier UAV platforms.

Typical Use Cases

• Public safety and emergency response: Persistent aerial observation and communications relay during incident management.
• Industrial inspection: Long-duration monitoring of refineries, power stations, pipelines and construction sites.
• Security and perimeter surveillance: Continuous overhead presence for critical locations (airports, data centers, stadiums).
• Events and broadcasting: Stable, powered aerial camera platforms for long events and live feeds.
• Communications relay: Temporary network or signal relay platforms in disaster recovery or remote operations.

Installation & Operation - Best Practices

Pre-Installation Checks

1. Confirm available on-site power: three-phase AC input is required for the tether box.
2. Ensure your drone accepts external high-voltage supply (800-1000 V) and supports the provided connector type (XT90 or adapter).
3. Inspect the drone's tether hook point and structural capability to handle cable tension and wind loads.

Startup & Flight Procedure

1. Adjust winch torque knob to the lowest setting before powering on.
2. Close the circuit breaker, switch on the main power box, start cooling fan and confirm the display readouts.
3. With the drone hovering at about 5 m, press "Main Power On/Off" to energize tether power - monitor voltage/current/power.
4. As the drone ascends, allow the reel to pay out the cable smoothly; maintain nominal, minimal tension to avoid slack.
5. During descent, switch torque knob from low to higher settings to maintain controlled reeling and tension; power off the tether at about 5 m altitude before final landing and retraction.

Shutdown

1. When the drone is near ground (about 5 m), turn off main high-voltage supply.
2. Carefully reel in the cable, avoiding snags; after full retraction, power off the main box and unplug the power cord.

Maintenance & Storage Recommendations

• Inspect the system every approximately 50 flights or about 20 flight hours: check reel operation, cable condition, connectors and fasteners.
• Store the system for long periods at recommended temperatures (ideally 22-28 C); avoid prolonged exposure below -10 C or above 45 C.
• Transport with adequate shock protection to prevent internal component loosening or damage.
• Keep onboard batteries (if used) at about 40-65% charge when stored for more than 10 days.

How AF-G15-100M Compares to Alternatives

The AF-G15-100M sits in the high-power/professional tier of tether systems due to its 15 kW nominal (<= 20 kW peak) output and 800-1000 V DC delivery. Compared to entry-level tether kits (which commonly deliver a few kilowatts and lower voltages), the AF-G15-100M supports larger UAV platforms, heavier payloads, and longer continuous missions - but it requires more site infrastructure (3-phase AC) and carries a larger footprint and higher cost.

Challenges & Operational Considerations

• Infrastructure: Requires three-phase AC on site - plan for generators or grid access for remote deployments.
• Compatibility: The UAV must accept the tether's high-voltage input and mechanical hook connection.
• Training: Operators should be trained to manage tether tension, reeling procedures, and emergency power shutdowns.
• Regulation: Check local flight rules and permissions for tethered operations and surveillance tasks.

SEO Tips for Your Shopify Product Article

Use the following guidelines to make your Shopify product article rank better on Google:

• Primary keyword: include "tethered drone power system" in the H1, first paragraph, and meta description.
• Secondary keywords: use long-tail phrases like "industrial tethered UAV solution", "800V drone tether power", and "tethered drone winch 15kW".
• Structured content: use H2/H3 headings, bullet lists, and a clear spec table so search engines can parse content easily.
• FAQ & Schema: add a short FAQ section (structured data) to capture "People also ask" features and rich snippets.
• Images & alt text: include at least one product image with alt text such as "AF-G15-100M tethering system winch and power box".
• Page performance: compress images, minimize scripts, and ensure mobile responsiveness.

FAQ

What power input does the AF-G15-100M require?

It requires a three-phase AC power input at the ground station; the unit outputs 800-1000 V DC to the drone.

How much continuous power can it deliver?

Nominal output is 15 kW, and maximum output is <= 20 kW.

Can the tether carry data as well as power?

Yes - the tether supports wired information transmission for telemetry, video, and control signals.

Is the system suitable for small consumer drones?

No - this system is designed for medium-to-large professional UAV platforms that accept high-voltage external power and have tether attachment points.

What safety procedures should operators follow?

Adjust torque knob to lowest before power on, operate with fans running and controls monitored, power down at about 5 m altitude prior to retraction/landing, and follow the manufacturer's checklist for pre-flight and post-flight inspections.

Conclusion

The UAVMODEL AF-G15-100M Tethering System is a high-power, professional solution for persistent UAV operations where continuous power and reliable data links are essential.
