Electromagnetic compatibility universal tester

The impact of lightning (indirect lightning) in nature and voltage changes caused by large switch switching in power supply lines on power supply lines and communication lines is particularly large, and the impact on products may be destructive. The lightning surge generator is used to evaluate the performance of the equipment when it is subjected to high-energy disturbance from the power line port and other signal line ports.

News Information

New energy vehicles

The on-board charger is built in the new energy vehicle, which is used to charge the on-board high-voltage battery from the AC grid when parking. The battery used is usually more than 400V, and is developing towards higher voltage and higher number of battery strings. In order to realize a faster and lighter vehicle charging scheme, the new trend of charging power is upgraded from 6.6kw to 11kw. Generally, the current flows from the grid to the battery in one direction, but there are also two-way flow design schemes. Nano chip micro provides complete solutions for isolation voltage, isolation current detection, isolation drive and isolation communication, helping customers achieve higher power density OBC solutions.

LED lighting

At present, if constant DC power supply is adopted for LED lighting lamps, which are more and more widely used, it is theoretically possible to achieve constant lighting without stroboscopic. But in fact, due to the lack of industry standards, the market competition is fierce and disordered, and the market is full of low-quality LED lamps, especially indoor low-power LED lamps, which also have stroboscopic problems. In order to obtain a pure constant current source, the LED driving power supply is the key to ensure that the LED lamp does not flash. At present, LED power supply can fully meet the requirements of no stroboscopic.

Medical equipment

"For medical equipment, electromagnetic compatibility should be considered at the time of design. Generally, there are three ways to rectify electromagnetic interference: shielding, grounding and filtering. Shielding materials or microwave absorbing materials can be used to help solve the electromagnetic shielding problem. The solution Zhaoke recommends using microwave absorbing materials to absorb electromagnetic waves and eliminate electromagnetic interference, which can effectively suppress the electromagnetic interference problem in electronic equipment."

On board electronics

Automotive control system is based on electronic equipment. The reliability of automotive electronic products is directly related to the safety and reliability of the whole vehicle. ITech has rich experience and products, and can provide mature, reliable and professional automotive electronic testing solutions for vehicle electronics, automotive central control box, automotive generator, relay, DC motor /dc-dc Converter testing, DC brushless motor, automotive fuse, lamp and other fields. ITech has a product line of automotive electronic testing instruments, with a maximum of 1152kw and a maximum voltage of 2250v.

Household Electric Appliances

The electromagnetic interference in the control board of small household appliances is mainly EMS interference, that is, electrostatic discharge, group pulse, lightning surge and other interference. The corresponding interference equipment names are: electrostatic discharge generator, group pulse generator, lightning surge generator. The interference of the control board of small household appliances mainly comes from three aspects: the first is the interference generated by the control board itself, the second is the interference from the load, and the third is the interference from the line.

Electric tool

In recent years, with the continuous development and wide application of electronic technology, the technology of hand-held electric tools is becoming more and more mature. While pursuing excellent performance, countries have higher and higher requirements for its electromagnetic compatibility, the corresponding standards are also constantly updated and improved, and the threshold of product certification and recognition is higher and higher. It is necessary to study the electromagnetic interference of electric tools and put forward some suppression methods.

Communication equipment

In recent years, economic development has promoted the improvement of China's scientific and technological level. With the progress and development of science and technology, communication tools have become more and more developed. At present, interphone, pager, wireless phone and other communication tools have increased sharply, forming an all-weather and all-round communication network, especially in modern enterprises, the lack of radio communication means is unimaginable. These communication tools provide convenience in leadership, command and business contact. However, the electromagnetic wave interference generated by radio communication poses a threat to the production safety and stable operation of enterprises, causing hidden dangers.

Low voltage electrical apparatus

Power supplies are widely used in modern electronic products, which need to have certain anti-interference ability, isolation and protection functions. Different countries and regions have a series of certification standards for various power supplies entering the market to ensure the quality of power products. ITech has a rich product line of power test instruments, including AC and DC sources, AC and DC loads, power analyzers, and its9500 power module automatic test system.
