Rated at 250 watts of output power, and packaged in an industry-standard open frame 3 x 5 inch, 1U footprint, this high-efficiency design can deliver its full output using convection cooling when operating in temperatures up to 50 °C. The PQC series accommodates the universal AC input voltage range from 90VAC to 264VAC and with a frequency range from 47Hz to 63Hz. The highly efficient convection cooling design employs optimal thermal management to deliver an energy efficiency rating of up to 95%.
The series currently is available in 12V, 15V, 18V, 24V, 36V, 48V or 5V 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 500mW of power in standby mode.
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).
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 ideal for powering equipment such as ultrasound monitors, blood pressure monitors, incubators, ECG equipment, and operating tables. EMI compliance is certified to EN55022 Class B conducted emissions.
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 series is less than 1U high and is available in open-frame and with a cover option.
