Applications

IT & computing

Workstations, mini PCs, POS terminals, printers and external storage. Active PFC above 0.95 meets EU ecodesign requirements for 75W+ external power supplies.

Professional AV

Amplifiers, professional displays, broadcast monitors and conference room equipment. Fanless designs up to 200W eliminate acoustic noise in studios and quiet environments.

Networking & telecom

Fiber ONUs, managed switches, edge routers and small-form-factor server appliances. 12-48V output options cover the full range of networking voltage requirements.

Medical devices

IEC 60601-1 certified models with 2x MOPP isolation and <0.1mA leakage for diagnostic, monitoring and treatment equipment. Specify medical-grade when proximity to patient is required.

Industrial controllers

CNC controllers, PLC power supplies, motor drives and test equipment. Desktop format provides higher power than wall adapters with better thermal management for continuous duty.

Gaming & entertainment

Gaming consoles, arcade machines, VR headset base stations and amusement equipment. High efficiency and full protection suite ensure reliable operation under demanding load profiles.

Desktop vs Wall-Mount vs USB-C Adapter: Which Form Factor?

The right AC/DC adapter form is set by available space, power level and whether the cable is user-detachable. XGW supplies desktop, wall-mount and custom adapter builds across 5W - 120W.

Desktop vs wall-mount vs USB-C adapter
FormBrick with IEC inlet + DC cableDirect plug-in, no cable brickPD over USB-C, low power

Choose desktop when you need higher wattage, a replaceable IEC cord for global plugs, or a separate DC cable that routes through a strain relief. Choose wall-mount to kill brick clutter on crowded outlets. All XGW adapters carry UL/CE/CB and interchangeable plug kits - see the adapter overview.

Frequently Asked Questions

Do you offer medical-grade desktop adapters?

Yes. Medical versions comply with IEC 60601-1 with 2x MOPP isolation and low leakage current. Specify your application when requesting a quote.

Can I get a custom output cable and connector?

Yes. Custom harnesses with barrel, terminal block, Molex or USB-C connectors are available. Send your pinout drawing for review.

What cooling is used at 300W?

High-power models use convection-optimized vented enclosures; fanless designs are available up to 200W for noise-sensitive AV environments.

Is active PFC included?

Yes, active PFC with power factor above 0.95 is standard on 75W+ models, meeting EU ecodesign requirements.
