Medical Power Adapter Technical Advantages and Standard Requirements

1.Safety Performance

Multiple Protection Mechanisms: Built-in over-current protection (OCP), over-voltage protection (OVP), short-circuit protection (SCP), and temperature protection (OTP) ensures that the power supply will be cut off within 0.1 seconds under abnormal conditions (e.g., short-circuiting of the output).

Medical grade certification: Complies with IEC 60601-1, GB 9706.1 and other standards, with strict regulations on leakage current (<100μA), creepage distance (>4mm) and insulation strength (>4kV AC).

2.Stability and Reliability

High-precision Output: Voltage accuracy up to ±1%, load adjustment rate <0.5%, ensuring stable operation of the device under dynamic load changes (e.g. ventilator inhalation/exhalation switching).

Long-life design: medical-grade capacitors (life>100,000 hours) and high-temperature-resistant components (operating temperature range -20℃ to +70℃) are used to adapt to extreme environments such as operating theatres and emergency vehicles.

3.Electromagnetic compatibility (EMC)

Anti-interference capability: EN 55011 Class B certified, suppressing electromagnetic interference generated by the power supply itself (e.g. switching noise <40dBμV) to avoid affecting sensitive equipment such as ECG machines.

Low-radiation design: Shielded transformer and filter circuit are adopted to control the conducted radiation (150kHz-30MHz) below 30dBμV.
