TH2818XA/TH2818XB Automatic Transformer Test System

TH2818XA/TH2818XB Automatic Transformer Test System

　 TH2818XA/XB is an Automatic Transformer multi-parameter Test instrument used for quality control of electronic transformer over a wide range of frequency (20Hz to300 kHz). Almost all low voltage transformer parameters can be scanned. The primary parameters include Inductance L, Leakage Inductance Lk, Turns-Ratio Tr, DC resistance DCR, Impedance |Z|, and Capacitance (between windings) C etc.; The secondary parameters include Quality Factor Q , ESR and Phase etc., Pin short can also be detected. The advanced digital sampling technique and high speed scanning test fixture make the transformer inspection more accurate and efficient, it was used to be low-efficient before the use of such a test system. TH2818XA/XB provides several signal output impedances for selection in order to be compatible with some well-known LCR instrument providers when an inductor is measured. Turns-ratio is calculated by the inductance of primary and secondary windings, which decreases the measurement error caused by large leakage of magnetic flux for example low coupling coefficient transformer. TH2818XA is also a precision impedance test instrument with 6 digit display resolution over a wide measurement range. It can be used for incoming inspection of components, quality control of product line and laboratory use.
