300W open frame AC-DC power supply with 1in profile

Vox Power in Ireland has launched a 300W open frame power supply with a low profile for medical and ITE applications.

The Vox EIRE300 series AC-DC open frame power supply delivers 300 Watts with a peak output of 375 Watts within a compact 4in x 2in footprint and a 1in profile. This provides a 37.5W/in³ power density with an efficiency reaching up to 95%.

The open frame is designed for integration into medical and industrial applications with 2 x MOPP isolation, low leakage currents, standard mounting holes and a dedicated auxiliary fan supply. Additional standard features include internal dual line fusing, remote sensing, and an AC_OK signal. The EIRE300’s low standby power consumption of typically 0.25W makes it suitable for energy-critical applications.

• 300W AC-DC power supply
• Configurable 600W AC-DC power supply

The series is not only certified to the latest international Medical and ITE Safety Standards but also offers a “BF” rating, making it suitable for equipment that requires direct contact with patients. This rating is crucial for applications like surgical instruments and critical care medical devices, ensuring that they can be safely used close to the patient without risk of electrical hazards.

The EIRE300 series has a range of output voltages from 12V to 60V, including standard options of 12V, 15V, 18V, 24V, 28V, 36V, 48V, and 54V. Each output has a wide adjustment range, ensuring compatibility with most non-standard voltage requirements within this range. Comprehensive protection features such as over-voltage, over-current, and over-temperature safeguards are standard.

Designed for both Class I and Class II equipment, the EIRE300 meets EMC Class B standards for conducted and radiated emissions. It is capable of operating at altitudes up to 5000 meters and is approved to 60601-1 and 62368-1 for medical and ITE applications, as well as compliant with 60601-1-2 (EMC), 60335-1 (Household appliances), 61010-1 (Measurement, Control & Laboratory Equipment) and 61558-1 (Safety of Power Transformers) standards.

The AC-DC power supply uses electrolytic capacitors for a longer lifetime and comes conformal coated as standard to protect against environmental contaminants with an operating temperature range of -40°C to +70°C and a calculated MTBF exceeding 500k hours.

Samples will be available from Q1 2025.
