UAVMODEL WF-1400S60-30K - high power density DC-DC module

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.

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

Verify input supply: ensure the HV DC supply is within 1,300 to 1,400 Vdc.
Cable & connector sizing: design for approx. 400 A output current; plan for cable losses and insulation for high voltage.
Cooling & ventilation: maintain airflow for the built-in fan; derate for high ambient temperatures or high altitude.
Environmental sealing: follow IP65 installation practices (avoid pooling water on enclosure, seal cable glands correctly).
Protection coordination: coordinate upstream fuses/breakers with the module's internal protection and its self-recovery behavior.
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.
