42W Medical Switching Power Supply

Medical power adapter is a key component that provides electrical energy to medical equipment, and its performance and safety standards directly affect the normal and safe operation of medical equipment. The standards for medical power adapters mainly include:

1. Voltage accuracy: Medical equipment has high accuracy requirements for power supply voltage, generally within ± 5%. The output voltage of the power adapter must ensure high accuracy and not produce significant changes or pulsations.

2. Current accuracy: The working current of medical equipment also needs to be accurately supplied and controlled, and the accuracy of the output current of the power adapter should be within ± 5%.

3. Carrier and noise: The output of medical power adapters must be pure DC power, without obvious carrier, pulse, and noise signals. Generally, a filtering accuracy higher than 50dB is required.

4. Stability: The output voltage and current of the medical power adapter must ensure high stability, so that even if there are significant changes in the input power supply, the output parameters can remain stable. Usually, it is required that the output voltage change should not exceed ± 1%.
