In CES and 14th Five-Year, the future technology is closely surrounded into two major topics: the smart medical device and Electric vehicles (EVs).
For a healthy lifestyle needs the combination of healthcare and technology
The coronavirus rages and global cases continue to break new records with newly discovered variants, Omicron. Integrating healthcare and technology helps health facilities and patients be well-prepared or protected for the ever-changing epidemic. Such as through smart medical devices, where real-time remote diagnosis and treatment can be realized. Further, it mitigates the risk of contacting the uncertain crowd and tracks patients’ physical status.
China’s economic development plan particularly supported the smart healthcare industry. Integrate the latest technology and data and medical care to improve citizens’ health. A great example is the most common household device is a cloud-based blood pressure monitor that effectively tracks chronic diseases. In the previous e-newsletters, we mentioned this product must comply with IEC 60601-1 (medical equipment basic safety and performance requirements) to ensure users’ safety. The required test includes ground bond, Hipot, and leakage current test. For detailed information, simply follow-up on issue 17.
Medical devices no only apply to diagnostics, monitor, and treat diseases, but also prevent illness. At CES, Razer launches a cool smart mask that brings technology into everyone’s new life of epidemic prevention. Due to its novel tech masks, the safety and quality need to be ensured by rigorous electrical safety tests.
Interestingly for masks. If the smart masks are advertised as medical-grade, they must comply with IEC 60601. Otherwise, they are classified as air purifiers and must comply with the household appliance standard IEC 60335. Generally, their power source is batteries, so the working voltage is in the safe voltage range and the Hipot test is not required. However, most products still have exposed metal parts, such as charging sockets. Although it is a non-carried metal part, it still can cause serious injury when a large amount of leakage current flows through it. Therefore, to ensure the safety of users, both standards required leakage current test. The testing voltage for different DUT has slight differences. Generally, apply up to 1.1 times the rated voltage to the non-carried metal part and connect a measuring device (MD) to simulate people touching the operating DUT situation. Leakage current limitation should be less than 0.25mA (depending on product design, this limitation will be slightly different). When the leakage current is greater than this, it will cause serious electric shock or injury to personnel. Guard the safety of end-users with the most severe simulation scenarios.
As being the first choice to the electrical safety testers for the medical device manufacturer, Ikonix have worked with many companies to protect the electrical safety of end-users. Healthcare is a life-saving industry, so companies must pay extra attention when selecting a reliable tester. It does not only focus on accuracy but also higher quality. Therefore, eec, an Ikonix brand ESA series Electrical Safety Compliance Analyzer and 7630 Touch Current Tester are indispensable testers in the production line. ESA series Electrical Safety Compliance Analyzer integrates AC and DC Hipot, insulation resistance, ground bond, and leakage current test into one. The 7630 Touch Current Tester is designed for leakage current testing. They also have built-in 7 different human-body-simulation measuring devices (MD) and 8 different testing fault condition simulations, creating diverse possibilities for replicating real-world conditions.
The electric vehicle market heats up
Attribute to energy saving, carbon reduction, and governments relevant policies, EVs and self-driving cars have been the hottest topics in recent years and continue to 2022. More and more companies are joining the EV race. For example, Sony has also proposed a few concept cars to the market. Accelerating the charging speed and enhancing battery life is still the focus of technological development. The related product includes the battery, motor, charging station, and charging-related accessories. Our e-newsletter has shared the EV industry-relevant test standard, requirement, and testing methods. The following table summarizes EV relevant standards and test methods:

Under the EV boom, many charging station manufacturers have expanded their production lines to respond to the increasing demand. For consistent quality and safety, they all choose the ESA series Electrical Safety Compliance Analyzer. The completed solution can perform electrical safety tests for different EV charging station specifications and standards. To conduct the EV charging station-related accessories electrical safety test, the best solution is the SE Series Electrical Safety Analyzer. The SE series has an AC/DC Hipot and insulation resistance test and a maximum output of 500VA that meets standards’ requirements. As the operating voltage increases continuously, the SE series provides test voltages up to 5kVac and 6kVdc and 32A ground bond testing current to meet the testing needs.
