ESD-2005Q
Electrostatic discharge generator
◆ introduction
Esd-2005q electrostatic discharge generator is a tester developed by Shanghai Yunque Electronic Technology Co., Ltd. which fully meets the requirements of IEC 61000-4-2 and GB / T 17626.2 standards in performance. The maximum electrostatic discharge voltage can reach 30KV, which can be used in the electrostatic discharge test of most electrical and electronic equipment, and can ensure the comparability and reproducibility of the test. The resistance capacitance kit is easy to replace, which is convenient for other standard tests, such as on-board electronics (ISO 10605 standard).
Application fields:
Industrial control, home appliances, medical electronics, communication electronics, components, automatic control, etc
◆ Technical features
Accurate discharge
The air discharge mode meets the standard requirements (the voltage is maintained for more than 5 seconds), which is the same as that of European and American products. The discharge is basically not affected by air humidity, and the discharge repeatability is good. Has little radiation interference and makes the test process very easy.
friendly interface
The color touch LCD interface has many functions, simple operation and convenient software upgrade.
IEC voltage, host automatic trigger mode, voltage rising scanning, automatic polarity switching, user
Intelligent functions such as self programming.
Intelligent program-controlled high-voltage power supply, high-voltage overvoltage, overcurrent and short-circuit protection
With self diagnosis function, it can intelligently judge the abnormal high voltage output
User programmable test program, up to 1000 sets of memory
High cost performance
The main components are all imported, with high precision and low failure rate. It works stably for 30KV for a long time. It is one of the few domestic electrostatic discharge generators that can obtain the measurement report of China National Accreditation Commission for conformity assessment (CNAs).
