In today’s rapidly evolving engineering landscape, design teams are constantly challenged to deliver more performance in less space—without sacrificing reliability, thermal stability, or compliance. For industries such as medical, industrial automation, test and measurement, and OEM system design, the pressure to build smaller, smarter, and more efficient equipment has never been greater.
Enter Vox Power’s EIRE300 series, a breakthrough open‑frame AC/DC power platform that delivers industry‑leading power density, superb efficiency, robust safety approvals, and long‑term reliability—all within an exceptionally compact footprint. According to TRC Electronics, the EIRE300 offers a compelling solution for design engineers who must balance power performance with tight space, thermal limitations, and global compliance requirements.
A Compact Footprint with Large‑Scale Capability
The standout feature of the Vox Power EIRE300 is its remarkable ability to deliver 300W continuous output from a footprint measuring only 4” × 2” × 1”—a form factor traditionally associated with far lower power ratings. This compact architecture enables equipment manufacturers to rethink how much performance can fit inside small enclosures.

Key power performance highlights include:
- 300W continuous output
- 375W peak power for 1 second—ideal for motor starts, transient loads, and high‑demand momentary events
- Up to 95% efficiency, reducing heat generation and easing thermal management
- 200W convection‑cooled rating at 115Vac, supporting fanless and noise‑sensitive system designs
This combination of power density and thermal performance allows the EIRE300 to excel in applications where every cubic inch matters.
Versatility for Multi‑Market Engineering
One of the EIRE300's most significant advantages is that it’s intentionally engineered for broad market compatibility. With approvals for both medical and industrial applications, the EIRE300 series helps design teams streamline supply chains and reduce the need for multiple specialized power modules.
Standout compliance and safety features:
- 2 × MOPP medical isolation, meeting IEC/UL60601‑1 requirements
- IEC/UL62368‑1 compliance for industrial and ITE systems
- Low leakage current, essential for patient‑connected medical devices
- EMC Class B performance for quiet operation in sensitive environments
This flexibility is especially valuable for manufacturers developing product families that must scale across hospital, lab, industrial, and automation settings. With a single power platform serving multiple verticals, engineering teams can accelerate time to market and reduce complexity.
