GaN Power Supplies – High-Efficiency Gallium Nitride Solutions

At Relec Electronics, we’re expanding our range of Gallium Nitride (GaN) power supplies, including high-performance external adapters and compact solutions for industrial, commercial, and specialist applications.

GaN technology is redefining what’s possible in power conversion — delivering higher efficiency, smaller size, and cooler operation compared to traditional silicon designs.

What is GaN in Power Supplies?

GaN (Gallium Nitride) is a wide bandgap semiconductor material used in modern power electronics. In power supplies, GaN switches can operate at much higher frequencies than silicon, handle greater voltages, and reduce energy losses during conversion.

For engineers, that means:

• More power in less space
• Improved thermal performance
• Lower energy consumption

The Benefits

• Higher Efficiency – Reduced switching losses mean less wasted energy.
• Compact Size – Smaller magnetic components and heat sinks thanks to higher switching speeds.
• Cooler Operation – Less heat generation for better reliability and longer lifespan.
• Lightweight Design – Ideal for portable and space-limited applications.
• Lower Total Cost of Ownership – Improved efficiency and reduced cooling requirements lower lifetime costs.

Our GaN Power Supply Range

Relec’s portfolio covers multiple application needs, with a strong focus on external power supplies for both industrial and commercial use.

Included product groups:

• External Power Adapters – Compact, lightweight, and compliant with global efficiency standards.

• Desktop Power Supplies – Ideal for bench-top, IT, and test equipment.

• High-Density AC-DC Modules – GaN-based designs for embedded systems.

• Portable Chargers – Small form factor for mobile and field applications.

Upgrade to GaN
