Next-Generation Aviation with This Generation’s Grid

As major airports worldwide pivot toward electrification, the shift from low voltage to High Voltage GSE equipment emerges, leaving airports facing a difficult choice: overhaul their entire electrical infrastructure or limit their fleet's growth.

The Infrastructure Challenge

Most major airports operate on an existing 150V DC bus: a reliable, established infrastructure designed for traditional GSE needs. However, as High Voltage GSE equipment emerges, the demand has outpaced standard grids.

01. Infrastructure Rigidness

Airports cannot easily or affordably replace the 150V DC bus systems that span across miles of tarmac and terminals.

02. Fleet Fragmentation

Airline ground operations are managing a "mixed fleet" of low and high voltage chargers, often requiring entirely separate power sources for each.

03. Upgrade Costs

Waiting for new transformers or trenching for high-voltage lines can take years and cost millions in capital and opportunity costs.

A Smarter Path Forward

Hardware Overview

Select the sections below to explore the engineering advantages of the DC Input Charger architecture.

Field-Replaceable Power Modules +

The product line features ultra-high reliability LITEON power modules with demonstrated mean time between failure (MTBF) exceeding one million hours. This modular power conversion architecture enables near continuous operational uptime while virtually eliminating maintenance requirements.

Direct DC & Multi-Voltage Input +

These chargers enable direct DC voltage inputs (120 to 420 Vdc) alongside standard AC inputs (240Vac single-phase, 208/240Vac three-phase, and 480Vac Wye). This is based on the EVQC030/060’s flexible Vac input power, now enabling Vac and Vdc inputs, thus reducing overall infrastructure and construction costs.

Closed-Loop Heat Exchanger +

A precision heat exchanger isolates the internal airstream from ambient air. The closed-loop thermal management system prevents dust and moisture from contacting internal power electronics.

NEMA 3S Enclosure & Safety +

Engineered with a rugged IP54/NEMA 3S rated weather-proof enclosure for reliable outdoor operation. The EVDC line is cETLus listed, meeting stringent UL 2202, UL 2231-1 & -2, and CSA C22.2 safety standards.
