Simplified design integration: The simplification of medical and industrial design can start with power supplies that have more functions and fewer requirements.
A major design factor that must be considered when selecting power supplies for the global market is whether the final device needs to be classified as a Class I or Class II device. The differences are not only in wiring, but also affect safety certification, insulation requirements, and overall system level design. Vox Power's EIRE300 series (Figure 1) allows Class I (grounded/protective grounded) and Class II (double insulated) applications to meet requirements using only a single component, thereby helping to simplify the development process. This flexibility allows engineers to reduce the number of approved power supplies required for different applications, thus simplifying testing and compliance processes regardless of market or architecture.

Class I installations are typically used in hospitals, laboratories, and industrial environments, which require good grounding connections to ensure safe operation so that current can be safely diverted from the user in the event of a fault. On the contrary, Class II devices are designed to be safe to use without grounding. Instead, they protect users by strengthening insulation. For portable or household devices that cannot guarantee reliable grounding, this function is crucial. With EIRE300, engineers can use only one component to meet the requirements of two installation types. This reduces engineering design time and accelerates regulatory approvals.
In addition, EIRE300 has also passed both IEC/UL 60601-1 (version 3.2) and IEC/UL 62368-1 (version 3) certifications, meeting the requirements of medical and industrial applications. This series is designed to comply with the 60601-1 standard, providing 2 x MOPP isolation and low leakage current (<100 μ A) to support BF grade applications that may come into direct or close contact with patients. 62368-1 certification means that it can be easily integrated into modern information technology and industrial applications that follow current hazard based safety schemes, allowing it to be integrated into equipment that balances mechanical design and safety.
In addition to security certification, EIRE300 is also suitable for environments where electromagnetic performance is crucial for system reliability. By meeting CISPR 11 (Class B) and EN 60601-1-2 4th edition conducted and radiated radiation standards, it helps ensure a quiet system power supply for sensitive applications such as diagnostic imaging, laboratory equipment, and compact control systems. EMC performance reduces design risk and integration time, especially when transitioning from traditional or discontinued power sources.
EIRE300 also has other practical advantages, which can simplify system design and integration. A standby power consumption as low as 0.25 W not only helps comply with global efficiency regulations, but also reduces the thermal load of applications in low-power states. A wide output voltage regulation range can also bring greater flexibility, supporting non-standard requirements without the need for complete customization. The rated power of EIRE300 for convective cooling at 115 VAC is 200 W, which is superior to many power supplies in the same category. It is compact in appearance and can provide up to 37.5 W/in ³ of power, helping engineers maximize power without expanding the size.
Whether installed in next-generation ventilators, compact laboratory instruments, or rugged industrial controllers, EIRE300 eliminates design compromises and raises engineers' expectations for certified open power platforms.
