Why Choose the A1.5 for Your Tethered Drone System?

The A1.5's compact 380g form factor makes it suitable for lightweight UAV builds without sacrificing power output.

Frequently Asked Questions

Q: Is the A1.5 compatible with my existing tethered system? 

A: The AF-400S24-1.5K is designed to work with Kitefly tethered power systems. Please contact us to confirm compatibility with your specific ground station setup.

Q: Why does the drone need to take off with a fully charged battery?

 A: For safety reasons, the drone must carry a fully charged battery at all times during tethered flight. In the event of a ground power interruption, the drone automatically switches to battery power, allowing for a safe emergency landing. The tethered power supply is not a replacement for the onboard battery — it works alongside it.

Q: Can I exceed 1500W by connecting multiple A1.5 units in parallel?

 A: No. The A1.5 is rated at a maximum of 1500W and should not be used beyond this limit. If your application requires higher power output, Kitefly offers other models in the series — please contact us to find the right match for your payload requirements.

Q: What is the warranty coverage? 

A: All Kitefly onboard power supplies come with a 1-year warranty covering manufacturing defects under normal operating conditions.

Q: What is the lead time and availability? 

A: The A1.5 is available in stock for immediate shipment. If current stock is insufficient for your order, lead time is 2–3 weeks. Contact us for real-time stock status and bulk order pricing.

Q: What are typical deployment environments? 

A: The A1.5 is suited for demanding field conditions including border security, critical infrastructure inspection, and public safety operations. For high-temperature environments such as the Middle East or India, we recommend consulting our technical team to confirm thermal compatibility with your specific installation.
