DuraComm Desk Top LPX-25 Power Supply - Compact, Efficient Desktop

Our review of the DuraComm Desk Top LPX-25 Power Supply finds it best for workshop benches and small server or communications racks where a reliable, efficient desktop supply is required. The single biggest reason to buy is its combination of full-range universal AC input and improved efficiency that meets DOE level VI standards, which reduces heat and waste in continuous-use environments. The LPX-25 keeps a familiar 7 in rugged desktop footprint while adding better electronic filtering and adjustable DC output, so it suits applications that need stable, filtered power without a bulky enclosure.

Key Features

• Universal AC input: The 90-264 VAC auto-ranging input lets the unit be used worldwide without manual switching, simplifying deployment.
• Active PFC and filtering: Built-in active power factor correction and enhanced filtering reduce line noise and improve voltage stability for sensitive electronics.
• 125% peak load capability: Temporary surges and startup currents are tolerated without shutdown, protecting connected devices during brief load spikes.
• Meets level VI efficiency: Improved energy conversion reduces losses and operating heat, which is useful for continuous-duty setups and green energy goals.
• Regulatory compliance: Conformance with Elsa 2007/DoE, NRCan, and EU ErP standards helps ensure compatibility with regional efficiency and safety expectations.
• Adjustable DC output: The adjustable output gives flexibility when powering a range of peripherals or custom equipment that need fine tuning.

Who It's For

The LPX-25 is aimed at technicians, system integrators, and hobbyists who need a compact, reliable desktop power supply for test benches, embedded systems, or small networking gear. Its universal input and robust filtering make it especially appropriate for mixed-voltage environments and installations that require continuous operation with efficient power conversion.

Those who need extreme miniaturization, built-in UPS capabilities, or exotic output voltages should look elsewhere; the LPX-25 is a rugged, standard 7 in desktop supply designed for stability and efficiency rather than maximum space savings or battery-backed runtime.

Pros & Cons

Pros

• High efficiency that meets DOE level VI reduces operating heat and energy waste.
• Universal 90-264 VAC input removes the need for manual range switching across regions.
• Enhanced filtering and active PFC deliver cleaner, more stable DC for sensitive electronics.
• 125% peak load capability handles short startup surges without tripping.

Cons

• As a desktop supply in a 7 in form factor, it is not optimized for ultra-compact installations where PCB-mount or brick modules are preferred.
• It does not include an integrated battery backup, so uninterrupted runtime requires an external UPS if needed.
