IT7800 series high power programmable AC/DC power supply, voltage ranges up to 350V L-N and 500V L-N. The IT7800 series provides multiple output modes such as single-phase, three-phase and reverse phase, which can be selected by the user through the panel menu. By programming, it can simulate three-phase unbalance, three-phase harmonic unbalance, lack of phase test, phase sequence reverse connection and other tests, which are flexible and cover more applications. Through the inverting mode, it can provide multiplier voltage output up to AC700/1000VRMS phase voltage, which can meet wind power generation, coal mine and other high voltage test requirements without series connection.
In the past two years, car networking, autonomous driving, unmanned driving, and automobile intelligence have become hot topics in the automotive industry, and have also guided the future development direction of automobiles. The purpose is to further improve the safety, reliability and comfort of vehicles during driving. For example, traditional emergency braking is controlled by the driver. Once the driver is in a state of fatigue driving, it is prone to traffic accidents. However, autonomous vehicles with a higher level can automatically determine the safety distance from the left and right vehicles, respond in milliseconds, and reduce their dependence on personnel.
The quality of the switching power supply is the guarantee of normal operation of the electrical and electronic equipment; therefore, it is critical to test the switching power supply. The paper focuses on analysis of the rise/drop time test and transient response time test of the switching power supply. In addition, the advantages of the IT8800 series programmable electronic load in both tests are elaborated.
The “high reliability” has become the most important feature of LED products and is directly constrained by the quality of the LED power supply.The ITECH IT8912E (500V/15A/300W) electronic load is a dedicated electronic load with the pure hardware circuit design for the LED power supply test. It is compatible with various LED constant current power supply tests.
Compared with the traditional battery, lithium-ion battery charge faster, last longer, and have a higher power density for more battery life in a lighter package. When you know a little about how they work, they can work that much better for you.ITECH ITS5300 battery test system can perform battery constant voltage, constant current, shelved, working conditions simulation and other charge and discharge step according to battery characteristics or the customer's requirements, which is suitable for all kinds of battery aging, cycle life test applications.
For wearable devices, in addition to product performance, the most important thing is the power consumption. The DUT is a heart rate tester module, which has a Bluetooth to monitor records timely. Using accurate voltage source IT6412 power supply and a high precision meter connected in series as a current measurement comparison.
The power industry always needskeep cost under control,while offeringreliable products. Under these pressure, strict product testing, dynamic application simulation and quality assurance measures are essential. ITECH is deeply aware of the importance of reliability and performance as we have provided the industrywith a variety of power supplies and loads, includingthe brand new high-power density electronic loadIT8900A/E which has both the high-performance and cost-effective strengths.
The professional electrical T&M instruments are required in smart socket RD and the check before leaving the factory. ITECH star product IT8615 AC/DC electronic load can be used to simulate the working status of different household appliance, and the IT7326 AC power supply can simulate the city AC power supply, and then to test the smart socket from a well-known brand.
