EIRE300

300W Single Output Open Frame Power Supply.

The EIRE300 is an open frame AC/DC power supply that combines compact design with exceptional reliability and efficiency. Delivering 300 Watts with a peak output of 375 Watts when fan-cooled within a compact 4” x 2” footprint and a slim 1” profile. It offers versatility with unrivalled convection-cooled ratings of 200 Watts at 115 V_AC, making it suitable for a wide range of industrial and ITE applications.

The product series offers power density exceeding 37.5W/in³ with efficiency up to 95%, significantly minimising power losses. The product series offers a range of outputs from 12V to 60V, including standard options of 12V, 15V, 18V, 24V, 28V, 36V, 48V, and 54V. Each output voltage has a wide adjustment range, ensuring compatibility with most non-standard voltage requirements within this range.

Engineered for seamless integration into industrial and ITE applications, the EIRE300 features 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 less than 0.5W makes it optimal for energy-critical applications.

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 latest international ITE Safety Standards, as well as compliant with 60335-1 (Household appliances), 61010-1 (Measurement, Control & Laboratory Equipment) and 61558-1 (Safety of Power Transformers) standards.

To maximise reliability and performance, the design utilises ultra long-life electrolytic capacitors and comes conformal coated as standard. Its high-efficiency design reduces heat output, supporting a wide operating temperature range of -40°C to +70°C, with a calculated MTBF exceeding 500K hours.

The EIRE300 series is also certified to the latest international Medical Safety Standards and 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
