Tethered Drone power system：

　　1. Advanced power conversion technology, with a typical efficiency of up to 96%, ensures stable and efficient power supply for drones during long-term flight.

　　2. The mooring box is equipped with intelligent automatic retraction and cable arrangement, and can also switch to manual mode by rotating the reel to retract and release cables. Configuring a 4.3-inch color screen with touch control is more user-friendly and convenient, with functions such as displaying box temperature, wire length, current and voltage, electricity consumption, torque adjustment, switching between Chinese and English, recording abnormal information, and a forced collection button. Relevant abnormalities will be promptly alerted through auxiliary reminders such as sound and light.

　　Tethered Drone Power Box: Technical Specifications and Support Guide

　　The cornerstone of any persistent aerial operation is a reliable, high-performance power source. Our Tethered Drone Power Box is engineered to be that cornerstone. Designed specifically for demanding, long-duration missions in security, broadcasting, and industrial inspection, this robust ground unit delivers unwavering power and stable data connectivity, enabling your drone to fly for hours, or even days, without interruption.

　　This guide provides a detailed overview of the Power Box's technical parameters, the comprehensive support that backs it, and the critical logistical information for handling and storage. Understanding these aspects is key to integrating our system seamlessly into your operations and maximizing its lifespan and performance.

　　Technical Parameters: Engineered for Reliability and Performance

　　Our Tethered Drone Power Box is built upon a foundation of advanced electrical engineering and rugged design. Below, we detail the core specifications that define its capabilities and ensure compatibility with your operational needs.

　　Electrical Input and Output Specifications

　　The Power Box is designed for global deployment with a versatile input range. It accepts AC input from 100V to 240V, at 50/60Hz, making it compatible with standard wall outlets and most generator sets across the world. For field operations or vehicle integration, it also supports a wide-range DC input from 24V to 60V. The core of its performance lies in the high-efficiency power output, delivering a continuous 900W to the tethered drone. This stable power flow is meticulously regulated to protect sensitive avionics and payloads onboard the drone, ensuring consistent performance throughout the mission.

　　Physical and Environmental Design

　　Constructed from a high-strength, lightweight aluminum alloy chassis, the Power Box is built to withstand the rigors of field use. Its compact form factor is designed for portability, with precise dimensions of 450mm x 300mm x 200mm and a net weight of 15kg. The unit features an IP54 ingress protection rating, making it resistant to dust and water splashes from any direction. This allows for confident operation in light rain or dusty environments. The operational temperature range is certified from -10°C to 40°C, with storage capabilities from -20°C to 50°C, ensuring functionality in a wide array of climatic conditions.

　　Core System Features and Data Connectivity

　　Beyond pure power delivery, the Power Box integrates several critical subsystems. A built-in Uninterruptible Power Supply (UPS) provides a critical safety buffer. In the event of a primary power source interruption, the UPS automatically engages, supplying sufficient power for a controlled, safe landing of the drone. The unit also houses the automated tether management control system, which regulates the payout and retraction of the tether cable, maintaining optimal tension. For data, the Power Box acts as a ground-side data hub, featuring Gigabit Ethernet ports for a low-latency, secure fiber-optic connection to the drone, as well as HDMI and USB-C ports for real-time video output and system diagnostics.

　　Compatibility and Integration

　　This Power Box is designed as the central component of our complete tethered drone system. It is fully compatible with our range of industrial-grade drones and our proprietary hybrid tether cables, which combine power conductors and fiber-optic data lines. The system communicates seamlessly with our web-based Ground Control Station (GCS) software, and we provide an open API for advanced users seeking to integrate the power and data stream into their existing command and control infrastructure.

　　Warranty and After-Sales Support

　　We stand behind the quality and durability of our products with a comprehensive support structure designed to give you peace of mind and minimize operational downtime.

Upon approval, you will receive instructions for shipping the unit to our nearest certified service center. Our standard service level agreement (SLA) aims to diagnose and repair most units within 5 to 10 business days of receipt. We also offer an advanced replacement service for eligible clients, where a replacement unit is shipped prior to the faulty unit's return to ensure minimal disruption to your operations. We strongly recommend adhering to recommended maintenance schedules, which include periodic internal inspection and cleaning, which can be performed by certified personnel or at our service centers.

　　Transportation and Shipping Requirements

　　To guarantee your Power Box arrives in perfect condition, please adhere to the following shipping and handling guidelines.

　　Packaging and Handling Specifications

　　The Tethered Drone Power Box is shipped in a custom-engineered, foam-lined hard case designed for maximum protection during transit. The outer packaging is a heavy-duty, weather-resistant cardboard box clearly marked with handling icons. The total shipping weight, including packaging, is approximately 18 kilograms. The package dimensions are 550mm x 400mm x 250mm. Always handle the package with care. Use appropriate lifting equipment for palletized loads and avoid dragging or dropping the package. The boxes should be stored upright and not have other heavy items stacked on top of them.

　　Global Shipping and Regulatory Compliance

　　We have extensive experience in shipping our systems worldwide via air, sea, and land freight. We provide all necessary commercial documentation, including a detailed commercial invoice, packing list, and certificate of origin. The Power Box contains integrated lithium batteries for its UPS system. All shipments are fully compliant with international transport regulations for lithium batteries, including IATA DGR Special Provision A188 for air transport and IMDG Code for sea freight. All required battery markings and documentation are provided to ensure smooth customs clearance. As the importer, you are responsible for ensuring compliance with any local import regulations and tariffs for electronic equipment.

　　Optimal Storage and Preservation Conditions

　　Proper storage is essential for maintaining the long-term health and readiness of your Power Box, especially during extended periods of non-use.

　　Recommended Long-Term Storage Environment

　　The ideal storage location is a clean, dry, and well-ventilated indoor facility. Temperature should be maintained consistently between -20°C and 50°C, with a relative humidity level below 70% to prevent internal condensation and corrosion. The storage area must be free from corrosive chemicals, excessive dust, and direct sunlight, which can degrade plastics and labels over time. Units should be stored in their original protective cases.

　　Preparation and Maintenance for Storage

　　Before placing the unit into long-term storage, it is crucial to prepare it correctly. Ensure the Power Box is powered down completely. We recommend charging the internal UPS battery to approximately 60-70% of its capacity. This charge level is ideal for battery preservation during inactivity. The unit should be inspected for any dirt or moisture and cleaned gently with a dry, soft cloth if necessary. For storage periods exceeding six months, it is advisable to perform a periodic maintenance check every three to six months. This check involves visually inspecting the unit for any signs of damage, verifying the storage environment conditions, and topping up the UPS battery charge back to the 60-70% range if it has depleted.
