A starter motor, also called a starter motor, is a motor used to start a diesel or gasoline engine. The starter motor can effectively reduce the trouble of manpower starting the engine, start more quickly, and can be used repeatedly. It is often used for starting automobile engines, starting generators, and starting large-scale construction machinery.

Market trend With the advent of the Internet of Things (IoT) era, wearable devices have come to you and me with the 5G communications. The world's major consumer electronics manufacturers, such as Apple, Samsung, Huawei, etc. have stepped into related fields. Low-power, high-performance electrical products are also constantly introduced, such as glasses, watches, electrical clothes ... and so on. In addition, health care is also using high-tech intelligent health monitoring, the most common methods are heart rate, blood pressure and pace monitoring.

From January 1, 2009, the latest effective version of the "Technical Instructions for the Safe Air Transport of Dangerous Goods" issued by the International Civil Aviation Organization (ICAO) has added the UN (United Nations) serial number of dangerous goods, and lithium batteries will be classified as Enter lithium ion batteries (UN 3090 and UN3091) and lithium metal batteries (UN3480 and UN3481). According to this regulation, if lithium batteries do not have a test report or relevant approval certificate based on UN38.3, they cannot be transported by air. The Civil Aviation Administration of China (CAAC) has issued the "Lithium Battery Air Transport Specifications" to airlines and dangerous goods-related transport units to strengthen the transport safety of lithium batteries.

Zero-volt load means that the electronic load can output a rated full current at a very low input voltage, and the current can be as high as hundreds of amperes. The electronic load has an unavoidable minimum internal resistance due to the conduction-drain-source internal resistance of the field effect transistor, and requires a certain minimum DC input voltage (UMIN) to enable the load to absorb the full rated current. Below this minimum operating voltage, the load current will decrease linearly. Usually below 3V, the load transistor is in the saturated working range, the current control ability becomes weaker, and the dynamic response becomes worse. The power supply voltage must be greater than the minimum operating voltage of the load, and the voltage drop of wires, relays, connectors, etc. under high current needs to be considered.

In 2022, Omicron will spread around the world, and the new crown epidemic will enter another round of peaks. Injecting the new crown vaccine is still one of the most powerful means of protection. But vaccine production is not evenly distributed around the world, and many impoverished regions need international assistance to complete the vaccinations. As we all know, vaccines need to be stored in a low temperature environment. How to ensure qualified storage and transportation in remote areas with poor infrastructure, such as African countries, has become an important issue. Vaccine refrigerators are widely used in terminals as a portable and independent storage device.

In the past few years, due to the large demands of solar energy, photovoltaic industry has embraced high speed development in China. However, it has presented slow increasing after booming at the very beginning with less and less demands. After the ‘5.31 new policy’ has been enforced, it’s urgent to alleviate the influences of decreased demands in a short time. So enterprises should work out how to obtain technology breakthrough or reduce costs. ITECH always devotes to explore test technology in applications of photovoltaic industry. We work with photovoltaic corporations and help them to become stronger, more precise and finally reach up to top level. Lately, ITECH will bring to market new product series, IT6000B/C/D with high performance, high voltage, high power density. You’ll find in this article how they are well applied to the test of photovoltaic inverters.
