Brief Introduction:

U2729 Series Automatic Transformer Test System is exclusively used in quality inspection for a variety of electronic transformers. This system can provide the test frequency of 20Hz-1MHz and all kinds of low-voltage transformer parameters can be scanned, including Inductance L, Leakage Inductance (Lk), Turns-Ratio (Tr), DC resistance (DCR), Impedance (|Z|), Capacitance (between windings) (C), Quality Factor (Q), ESR and Phase, Pin short inspection PS, balance test BAL, LED, forward voltage drop Vf/ reverse current Ir test. Adopting advanced digital sampling technique and high-speed scanning test fixture can meet the efficient and accurate testing requirements of many switching transformer and network transformer manufacturers.
