In recent years, due to COVID-19, the need for medical devices has increased quickly, having a direct and positive impact on medical power supplies. Today we are going to introduce medical power supplies. Medical devices are strictly regulated to ensure the safety and to protect the patient and operator due to direct physical contact to the human body, the safety standard of medical power supply is based on IEC 60601-1, the required safety level standard is higher than that of ITE/industrial safety standard. The required level of insulation and leakage current is strict. We provide medical power supplies compliant to IEC/EN/UL 60601-1, indicating the product safety and quality are ensured.
Like we mentioned previously, the first priority of medical device and power supply is safety protection. Medical devices must include at least one means of protection (MOP) to ensure both the patient and the operator are protected from the risk of electric shock, even in the condition of failure. The need of MOPs may be fulfilled by dielectric strength, creepage distance, and air clearance.
Moreover, we may find out the required dielectric strength between primary and secondary sides for universal input power supplies for medical power supplies is 4000 Vac which is stricter than 3000 Vac for industrial and consumer products. In the standard, operators and patients are regarded differently, and the means of protection are classified based on the following: MOOP – “means of operator protection” and MOPP – “means of patient protection”.
