When it comes to medical equipment, even the smallest components need to perform flawlessly. Vox Power’s VCCS300M, supplied by Relec Electronics, is a standout choice, offering high efficiency, a compact footprint, and medical device safety certification to EN60601.

Compact Design and High Efficiency

The VCCS300M delivers a silent 300 Watts of continuous output power in a remarkably compact 4” x 2” x 1.61” package. This small footprint is ideal for medical devices where space is limited. With power densities exceeding 23W/in³ and efficiencies up to 95%, the VCCS300M is perfect for applications requiring a balance of size and performance, such as portable diagnostic equipment and patient monitoring systems.

Unparalleled Safety Standards

Safety is paramount in medical applications, and the VCCS300M is designed with patient protection in mind. It is certified to the latest international Medical and ITE Safety Standards (EN60601) and boasts a “BF” rating, making it suitable for equipment requiring direct contact with patients. This rating is crucial for applications like surgical instruments and critical care medical devices safety, ensuring safe usage close to the patient without risk of electrical hazards.

Case Study: Highlighting VCCS300M’s Versatility


In the midst of a pressing demand for dependable ventilators in intensive care units (ICUs), a leading medical equipment company was in search of a reliable power supply to support their new ventilator design. This design required a power supply that not only fit within a compact frame but also offered high efficiency and ensured the utmost patient safety with minimal operational noise.


Designing a ventilator that meets stringent medical standards is no easy feat. The company faced several critical challenges:

ADEL System DIN Rail compact size

Compact design

The power supply needed to fit within the limited space of the ventilator without compromising performance.

Patient Safety

Given the sensitive ICU environment, the power supply had to be ultra-reliable, with minimal noise to avoid disturbing patients, and adhere to medical safety standards, particularly the “BF” rating for body floating applications. 

High efficiency

It was essential to have a power supply that maximised energy use to ensure the ventilator could operate continuously without overheating or energy loss.


After an extensive evaluation, the VCCS300M power supply was selected. This model stood out for several reasons: 

Silent Operation

Its design ensures virtually silent operation, crucial for maintaining a peaceful ICU environment. 

High power density

Despite its compact size, the VCCS300M delivers substantial power, perfectly fitting the space constraints without compromising on performance.

"bf" rating

The VCCS300M’s “BF” (Body Floating) rating ensures it meets stringent safety standards, making it safe for use in medical applications where direct patient contact is a factor.

VCCS300M, the pinnacle of medical device safety


The integration of the VCCS300M power supply into the ventilator design yielded excellent results. The ventilators operated reliably, providing continuous support to critical care patients without interruptions. The power supply’s compact size and high efficiency streamlined the ventilator design, making it easily manoeuvrable in ICUs. Its silent operation and compliance with medical safety standards ensured a safe and comfortable environment for patients. This case highlights the importance of choosing the right power supply in medical device design, particularly in high-stakes environments like ICUs.
