Introduction

In the rapidly evolving unmanned aerial vehicle (UAV) and tethered drone industry, reliable, high-power DC power supplies are critically important. The WF-1400S60-30K from UAVMODEL is engineered as a specialist high-voltage DC module converter - accepting a 1,300 to 1,400 Vdc input and delivering a 60 Vdc output at up to 24 kW continuous (30 kW peak). With efficiency >= 97%, robust protection features and a compact aluminium-shell design, it is ideal for tethered UAV systems and other industrial HVDC-to-DC applications.

Key Technical Highlights

• High-voltage DC to DC isolated conversion (1,300 to 1,400 Vdc -> 60 Vdc).
• Rated output power: 24 kW; Peak output power: 30 kW.
• Efficiency: >= 97% (measured at Vin approx. 1350 Vdc, load >50%).
• Compact aluminium-shell design, IP65 environmental rating, salt-spray and moisture protection.
• Comprehensive protection: input under/over-voltage, output over-voltage, over-current, short-circuit, over-temperature.
• MTBF >= 100,000 hours under rated conditions.

Detailed Specifications

Note: For full electrical protection thresholds (input under/over-voltage range, output recovery, etc.) consult the official product datasheet or the vendor page.

Applications & Use Cases

This power module is designed for scenarios where a high-voltage DC link is used to reduce cable losses and deliver sustained high power - including:

• Tethered UAV systems: ground-based HVDC supply converted to 60 Vdc for onboard systems or downstream converters.
• Outdoor industrial installations: remote monitoring stations, unmanned ground/marine vehicles, persistent lighting or communications relays.
• Replacement for imported HV modules: cost-effective substitute for comparable imported high-voltage DC module power supplies.

Benefits at a Glance

• High efficiency - minimal heat dissipation and reduced cooling needs.
• High power in compact form factor - suited to space/weight constrained systems.
• Rugged and outdoor-ready - IP65 plus salt-spray/moisture treatment.
• Comprehensive protections - enhances system reliability in mission-critical uses.
• Designed with UAV integrations in mind - suitable for tethered drone architectures.

Integration Guidelines

1. Verify input supply: ensure the HV DC supply is within 1,300 to 1,400 Vdc.
2. Cable & connector sizing: design for approx. 400 A output current; plan for cable losses and insulation for high voltage.
3. Cooling & ventilation: maintain airflow for the built-in fan; derate for high ambient temperatures or high altitude.
4. Environmental sealing: follow IP65 installation practices (avoid pooling water on enclosure, seal cable glands correctly).
5. Protection coordination: coordinate upstream fuses/breakers with the module's internal protection and its self-recovery behavior.
6. Ripple-sensitive payloads: consider additional filtering if payload electronics require lower ripple/noise than <= 700 mVp-p.

Installation & Commissioning Checklist

• Pre-installation: verify input voltage, grounding, ambient conditions, and cable routing.
• Mounting: secure with clearance for airflow; protect from direct water pooling.
• Wiring: connect HV input and 60 V output with rated cables; ensure correct polarity.
• Cooling: confirm fan operation and keep vents clean.
• Commissioning: power up, verify output voltage, load ramp tests and controlled protection tests if safe.
• Maintenance: inspect connectors, fans, vents regularly, and log fault events.
