[New] New Open-Frame 300 Watt Medical Grade Power Supply
maf300 medical ac/dc
P-DUKE has added a new 300W output power series, MAF300, to its medical grade AC/DC power supplies portfolio range from 15W to 450W. MAF300 is designed for dedicated medical applications with the highest insulation of 2xMOPP, in accordance with IEC 60601-1. It has a low leakage current of less than 100uA which makes it suitable for BF (body floating) medical equipment. The high conversion efficiency of up to 93% and the power consumption of less than 300mW allows for a power module design in a compact 4”x2” dimension with a power density of up to 24.92W/in³. Additionally, its output can deliver up to 360W peak power for 5 seconds to support a variety of automation systems and motor/valve devices in the medical field.
MAF300 features 4000Vac input to output isolation, an operating altitude of up to 5000m and a broad operating ambient temperature range from -40 to +85℃ which make MAF300 very suitable for any harsh environment applications. It comes in 4x2 inch open frame versions, optional encased versions or DIN-rail versions with a universal input range of 85 to 264 Vac and especially supports 120-370Vdc input range. This series provides 12, 15, 18, 24, 28, 36, 48, 53 Vdc single output voltages. The output voltage can be easily adjusted up to ±10% with the integrated potentiometer. A 12Vdc auxiliary output is available for a temperature controlled variable speed fan. The optional remote control and power good signal offer a convenient approach to controlling and monitoring the unit. They have the following protection functions: over-voltage protection (latch mode), over-current protection (hiccup mode and auto-recovery), short-circuit protection (continuous and auto-recovery) and over-temperature protection (sensed by an internal thermistor; hiccup mode and auto-recovery).
ISO 14971 risk management file is available to support designers in their risk analysis end evaluation on their system.
The MAF300 power supplies have been certified to the following standards:
IEC/EN/UL 62368-1
ISO 14971 Risk Management File
Conducted emissions: EN 55032 Class B
Radiated emissions:    EN 55032 Class A
MAF300 has the most compact design within the same power range of power supplies, it is ideal for medical diagnostic equipment such as MRI scanners, laser treatment, X-ray and patient monitoring, etc.
