Frequently Asked Questions
What is the smallest medical power supply Cosel offers?
The PMA30F-5 is one of Cosel's smallest medical power supplies: Dimensions: 50 x 30 x 100 mm (W x H x D); Power: 30W output capability; Certification: Full IEC 60601-1 3rd Edition with 2xMOPP; Isolation: 4000VAC with <30µA leakage. Even smaller options: PCB mount modules for embedded designs; External adapters for portable equipment; Custom solutions for specific applications. Size comparison: PMA30F-5: 150cc volume; Typical competitor 30W: 200-250cc volume; PCB mount modules: 20-50cc volume. For the smallest footprint, consider PCB mount modules. For enclosed supplies, PMA30F-5 offers excellent power density. Contact our FAE team for size-optimized solutions.
PMA30F-5 is compact enclosed option. PCB mount available for smaller footprint. Contact us for size optimization.
Can I use the PMA30F-5 in battery-powered medical devices?
The PMA30F-5 is designed for AC input, not direct battery operation: AC input: 85-264VAC for line-powered devices; Not suitable for direct DC battery connection. For battery-powered medical devices: Use DC-DC converters designed for battery input; Consider Cosel's CBS series DC-DC converters; Or use AC adapter + internal DC-DC architecture. AC adapter solution: Use PMA30F-5 in external AC adapter; Adapter plugs into wall outlet; Low voltage DC to device; Device contains battery and charging circuit. This architecture: Provides medical isolation in adapter; Allows battery operation; Simplifies device safety certification; Common for portable medical devices. Contact our FAE team for battery-powered medical device power architecture.
PMA30F-5 is AC input. Use in external adapter for battery devices. Contact us for architecture design.
What is the hold-up time of the PMA30F-5?
The PMA30F-5 provides typical hold-up time of 16ms at 230VAC: Hold-up time: Duration output remains regulated after AC loss; 16ms typical at full load, 230VAC; Varies with input voltage and load. 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: 16ms 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; Use higher power supply at partial load; Implement UPS or battery backup. Calculate required capacitance based on power and required time. Contact our FAE team for hold-up design.

How do I verify the 2xMOPP isolation in my design?
Verifying 2xMOPP isolation requires several steps: Design review: Check creepage distances (8mm minimum); Verify clearance distances (5mm minimum); Ensure no components bridge isolation; Confirm PCB material CTI rating; Documentation: Obtain isolation diagram from datasheet; Maintain risk management file; Document safety critical components. Testing: Hipot test at 4000VAC for 60 seconds; Check leakage current <100µA; Verify insulation resistance >10GΩ; Perform dielectric withstand test. Production: 100% hipot testing recommended; Statistical sampling for leakage; Maintain test records for traceability. Certification: Work with notified body for approval; Provide complete documentation; Demonstrate compliance with IEC 60601-1. The PMA30F-5 is pre-certified, simplifying this process. Contact our FAE team for isolation verification procedures.

What is the inrush current of the PMA30F-5?
The PMA30F-5 has controlled inrush current of 25A peak maximum at 230VAC: Inrush current: Surge when input capacitors charge at startup; 25A peak typical, <10ms duration; Controlled by internal inrush limiting circuit. For system design: Input fuse: 1A slow-blow (T1A) at 230VAC; Circuit breaker: Type C curve rated for inrush; Staggered startup for multiple supplies. Considerations: Brief duration (<10ms) minimizes thermal impact; Higher at cold start, lower at warm start; Higher voltage produces higher inrush. For systems with strict inrush limits: Use NTC thermistor for additional limiting; Implement active inrush limiter; Consider staggered power-up sequence. The inrush is within normal limits for 30W supplies. Contact our FAE team for inrush calculations.
