According to different frequency ranges, TH2829X provides three types of testers for your choice: TH2829AX with a frequency range of 20Hz to 200kHz,with the resolution of 0.5mHz and accuracy of 0.05% which can meet your test requirement in your current and future product tests.
In addition, TH2829X has equipped a 5mV-10Vrms signal source with a 100μV resolution thus helping you makie more accurate test. In combination with test technology, control technology, display technology and processor technology, TH2829X realizes an unbeatable test speed: 75meas/sec. Compared with TH2819X, the scanning speed has improved 40%. With such a fast test speed, your test and production efficiency will improve a lot and further reduce your production cost. When you only need to know PASS or FAIL, you can turn off the LCD display and then PASS/FAIL LED indicator on TH2829X front panel will show you test result. In this case, the test speed is about 1.5 times faster than that of TH2819X and you can benefit from such a speed as well. Most network transformers have diode or LED, but previous transformer tester cannot provide the diode P/N characteristic detection function. For network transformer manufacturers, this deficiency brings much inconvenience to their tests and even becomes the bottle-neck of efficiency improvement.
Now TH2829X can help them solve this problem by configuring an effective diode P/N characteristic detection function. Users can set its positive constant current source from 0 to 200mA and its negative current to 1μA. When providing strong test functions, we still try to reduce your budge. 0-100mA/10V bias source is an indispensable function for transformer test, but it is an optional funcion in the past and you have to pay more for it. But now, this function is a standard one on TH2829X, your budget can be greatly reduced. 100mA bias source and 1A bias source are both available on TH2829X. On previous transformer test systems, only 100mA bias source or 1A bias source can be installed, but now the two bias source have been equipped to TH2829X at the same time and users can make independent control on them on the front panel. The electronic transformer is a kind of special electronic components that has multiple pins and parameters and their tests need the test system to scan various parameters. For the limit of display devices, the test results have to be displayed in several pages on previous transformer test systems, and in order to view all test results, users must turn pages for several times. TH2829X can display all test results of single scanning test in one page and bring much convenience to user's observation and view. When the LCR test function is selected, the display cannot only display primary and the secondary parameters in traditional mode but also display two groups of primary and secondary parameters at the same time. In this way, more information can be displayed and users do not need to change the required parameter menus frequently. Through the USB HOST interface on the TH2829X front panel, you can save the required data to your external USB disk. Beyond that, the status file, transformer scanning test results, LCR parameters and current displayed page can be quickly saved to the internal FLASH. Users can save those data as CSV, XLS, GIF format so as to print, summarize, store and analyze. Turn ratio test is a vital item in electronic transformer parameter test, but the wide turn ratio range and the weak electromagnetic coupling are the main obstacles to their accurate measurements. By a series of technologic improvements, such as 10Vrms test signal, unique sampling and composing methods for transformer primary and secondary signals, improved calculation method for turn ratio, the turn ratio test made by TH2829X can be faster, more accurate and reliable.
TH2829X has a better test ability for low DCR, that is to say the tester can realize an accurate and stable measurement even when DCR is quite low. This ability ensures a reliable test for small-number and large-diameter coils. TH2829X can read the bar-code of DUT through USB HOST port. This function can set bar-codes for previous setting files for create a new file by scanning a bar-code to the tester. The corresponding test file will be easily found by reading the bar-code or manually inputting the bar-code. Bar-code management function can improve your management abilities of products and files. 10/100 Base-T LAN interface is a standard configuration for TH2829X. Through an HUB, several testers can be connected to a common PC from their LAN interfaces. With the networking software that Tonghui provides, users can build a networking and automatic transformer test system and further realize the networking control for several transformers. All setting files can be programmed on the PC and be sent to each tester. Users can view the test process of each tester on PC. In addition, test results can be uploaded to the PC through the network so as to make storage, statistic and analysis. TH2829X can store up to 200 setting files in the internal memory, so it is hard to search a particular file. For this point, TH2829X provides several file searching methods. When you input a key word, fuzzy search can find relative corresponding file. As stated above, bar-code search can find the corresponding file when you manually input or scan a bar-code. Tonghui has marketed the automatic transformer test system for many years and TH2818X/TH2819X automatic transformer test system has gained a lot of trust and support from our customers.
TH2829X is completely compatible with all test fixtures, test fixture jigs, control interfaces and setting files of TH2818X/TH2819X. Scanning test fixtures, TH1901 and TH1805, can be directly used on TH2829X. You do not need to worry about the incompatibility problem of the old and the new testers. Cost reduction, technology advancement and PASS rate improvement are main ways for transformer manufacturers to increase profits and productivity. TH2829X offers you statistic analysis functions such as Cpk, Ck and Cp. Users can choose test results of several parameters (less than 5 parameters) to make analysis. By this method, analysis data can be quickly gained and used to improve products. Number of samples that can be used to make analysis us up to 9,999. The working principle of transformer scanning fixtures is to apply an array of hundreds of relays to scan and switch different test pins and signals. For the long and frequent use of relays, their contact performance will decrease, which will further affect scanning test results. TH2829X can self-test the performance of scanning relays and find out failed relays, so users can make repairs in time and ensure that scanning fixtures work well all the time.
