Murata announces its new wide input range, single output PQC series of industrial/medical power supplies from Murata Power Solutions. Rated at 250 watts of output power in an industry-standard open frame 3 x 5 inch, 1U footprint, this high-efficiency design can deliver full power with free-air natural convection cooling up to 50°C. The PQC series features a universal AC input voltage range from 90Vac to 264Vac with any input from 47Hz to 63Hz. The highly efficient convection cooling design employs optimal thermal management and high power efficiency up to 95%.
The PQC series is currently available in 12V, 24V, 36V, and 48V, variants, each with a 5V standby as a standard feature. Additional output voltage variants are currently under development including 54V scheduled for a June 2017 release. Featuring remote enable, the PQC consumes less than 500mW of power in standby mode. These power supplies can continuously deliver full output power across the wide temperature range 0°Celsius to 50°Celsius and up to 70°Celsius (with derating).
These highly efficient power supplies carry medical, consumer, and ITE safety approvals and incorporate 2XMOPP (Means of Patient Protection) isolation. With an isolation of 4000 Vac (input to output) or 1500 Vac (input to PE), these units are ideal for powering equipment such as ultrasound monitors, blood pressure monitors, incubators, ECG equipment, and operating tables.
Where an application requires more power or redundancy, the droop current share characteristic enables two or more power supplies to operate in parallel to increase output current capability and flexibility.
The PQC250 complies with major international IEC/EN/UL 60950-1 safety standards and EMI to EN 55022, Class B.
The PQC’s advanced design delivers an EMI performance to Level B conducted and radiated emissions.
