TH7105 45.0Hz-500Hz AC Power Supply Power Electronic Tester

Programmable and Remote Control: Advanced DC Power Supplies offer programmable features and remote control capabilities. They can be interfaced with computers or control systems through various communication protocols such as USB, Ethernet, or GPIB (General Purpose Interface Bus). This allows for automated testing, remote operation, and integration into larger test setups or manufacturing systems. Programmable DC Power Supplies often provide software interfaces or programming languages for creating custom test sequences and automating complex power profiles.

Company Profile

Overview

Changzhou Tonghui Electronic Co. Ltd. was founded in 1994. It is a provincial high-tech enterprise integrating R&D, manufacturing and marketing. It is located in the National Development Zone – Changzhou Hi-tech Industry Development Zone with superior geographical position and beautiful natural environment. Covering a land area of 38000 m2 with construction area of 3000 m2. The company has more than 200 employees. More than 75% have college education or above. R&D personnel takes up more than 25% of total employees, and annual R&D investment exceeds 10% of company’s annual revenue.

For the past more than 20 years, Tonghui has been devoting itself to the research and development of electronic measurement instruments. Bearing the faith of technology first, we are struggling to promote the development of domestic measurement instruments and minimize the distance with the world advanced instruments. The company establishes “Changzhou electronic component measuring instrument engineering research center”, which has undertaken the ministry/province/city/district science and technology project for many times, and won the provincial/city science and technology progress award for many times. As a result of years of effort, Tonghui has grown to be a well-known brand in electronic instrument industry.

Now we have developed the following products: Electronic component parameter test instrument, Winding component test instrument, Cable harness test instrument, Electrical safety test instrument, Resistance test instrument, Power electronic testing instrument, Data acquisition/recorder, Digit multimeter, and other instruments, as well as accessories and software products. Tonghui insists to provide users with creative solutions for more efficient measurement and higher product quality. Tonghui has a mature quality control system and strong product manufacturing and quality assurance team, to ensure that the products delivered to customers can meet the unified quality standards.

“To achieve customer satisfaction” is the principle that Tonghui always adheres to. Over the years, Tonghui has been striving to build a multi-level marketing system, integrating direct marketing, agency and network sales. We have also established an after-sales service system in more than 20 provinces and cities in China, which helps better serve our customers, and listen to customers.

At present, the overseas market has become an important part of the development of Tonghui business. Tonghui has gradually integrated the technology and experience accumulated over the years into the international competition system. It has established marketing systems in North America, Europe, Southeast Asia and South Asia and has achieved fruitful results, enabling high-tech products from China to meet the needs of worldwide customers. Meanwhile, we can continue to enrich our experience in the exchange of learning with international counterparts. Looking forward to the future, Tonghui will fully expand overseas resources and realize the same value in all aspects.

In 2015, Tonghui was successfully listed on National Equities Exchange and Quotations (stock code: 833509). With the help of the capital market, Tonghui will open a new chapter of healthy development. Tonghui will always be your reliable friend and always look forward to sharing success and future with you.
