The PQC series can continuously deliver full output power across the wide temperature range 0°C to 50°C and up to 70°C (with derating), according to Murata.
Murata has rolled out a new wide input range, single output PQC series of industrial/medical power supplies. Rated at 250W of output power in an industry-standard open frame 3in x 5in, 1U footprint, the devices 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, while the highly efficient convection cooling design employs optimal thermal management and high power efficiency up to 95%, according to Murata.
Featuring remote enable, the PQC consumes less than 500mW of power in standby mode, the company said. These power supplies can continuously deliver full output power across the wide temperature range 0°C to 50°C and up to 70°C (with derating).
Murata's latest power supplies carry medical, consumer and ITE safety approvals and incorporate 2XMOPP (Means of Patient Protection) isolation. With an isolation of 4000Vac (input to output) or 1,500Vac (input to PE), these units are ideal for powering equipment such as ultrasound monitors, blood pressure monitors, incubators, ECG equipment and operating tables.
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, according to Murata.
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, the company said.
