95%-efficient, convection cooled AC-DC medical PDSUs
The design can deliver its full output using convection cooling when operating in temperatures up to 50C. The PQC series accepts universal AC input from 90 VAC to 264 VAC and with a frequency range from 47 Hz to 63 Hz.The PQC series currently is available in 12, 15, 18, 24, 36, and 48V single output variants, each with a 5V standby supply as standard. Additional output voltage variants are currently under development including 54V scheduled for a June 2017 release. Featuring remote enable, the PQC consumes less than 500 mW of power in standby mode. The series conforms to medical, consumer, and ITE IEC/EN/UL 60950-1 safety approvals and incorporates 2 X MOPP (Means of Patient Protection) isolation. With an isolation of 4000 VAC (input to output) or 1500 VAC (input to PE), these units are suitable 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.
