Frequently Asked Questions
What is the difference between PMA30F-5 and PMA60F-12?
The PMA60F-12 offers twice the power (60W vs 30W) with different output voltage: Output voltage: 12V vs 5V; Output current: 5A vs 6A; Leakage current: <40µA vs <30µA; Physical size: Slightly larger; Efficiency: 89% vs 88%. Both provide 2xMOPP isolation and meet IEC 60601-1 3rd Edition. The PMA60F-12 is ideal for medical devices requiring 12V at moderate current. Choose based on your voltage and power requirements. Contact our FAE team for selection guidance.

Can the PMA60F-12 be used in home healthcare devices?
Yes, the PMA60F-12 is ideal for home healthcare devices: Full 2xMOPP certification for patient safety; <40µA leakage current well below limits; 350K hour MTBF for reliable home use; -20°C to +70°C operation for various environments. Suitable home healthcare applications include blood pressure monitors, pulse oximeters, CPAP/BiPAP machines, nebulizers, infusion pumps, portable diagnostic equipment, and home dialysis equipment. The medical certification and safety features make this supply suitable for devices used by patients at home. Contact our FAE team for home healthcare design assistance.

What is the hold-up time of the PMA60F-12?
The PMA60F-12 provides typical hold-up time of 15ms at 230VAC: Hold-up time is the duration output remains regulated after AC loss. 15ms typical at full load, 230VAC. For longer hold-up: Higher input voltage provides longer hold-up; Lower load extends hold-up time; External capacitance can increase hold-up. Medical applications: 15ms typical ride-through for AC line transients; May need UPS for longer interruptions; Consider hold-up requirements for patient safety. For critical applications requiring longer hold-up, add external bulk capacitance or use higher power supply at partial load. Contact our FAE team for hold-up design.
15ms typical hold-up. Add external capacitance for longer. Contact us for hold-up design.
How do I verify the 2xMOPP isolation?
Verifying 2xMOPP isolation requires several steps: Design review includes checking creepage distances (8mm minimum), verifying clearance distances (5mm minimum), ensuring no components bridge isolation, and confirming PCB material CTI rating. Testing includes hipot test at 4000VAC for 60 seconds, checking leakage current <100µA, verifying insulation resistance >10GΩ, and performing dielectric withstand test. Production should include 100% hipot testing and statistical sampling for leakage. The PMA60F-12 is pre-certified, simplifying this process. Contact our FAE team for isolation verification procedures.

What is the inrush current?
The PMA60F-12 has controlled inrush current of 30A peak maximum at 230VAC: Inrush current is the surge when input capacitors charge at startup. 30A peak typical, <10ms duration. Controlled by internal inrush limiting circuit. For system design: Input fuse should be 2A slow-blow at 230VAC; Circuit breaker should be Type C curve rated for inrush. The inrush is within normal limits for 60W supplies. For systems with strict inrush limits, use NTC thermistor for additional limiting or implement active inrush limiter. Contact our FAE team for inrush calculations.
