产品详细信息
TH1775 is a DC Bias Current Source (or DC Magnetization Current Source) used Specifications
for inductance measurement of inductors and transformer windings with DC bias current.
Except for constant current output, low additional error and wide frequency
response range are important for bias current inductance measurement.
High frequency LCR meter could be used, when the frequency response range is wide enough.
MPU controlled auto current balance technology is adopted to realize AC+DC current overlap
and constant current output from 0 to ±20A. Two TH1775 can be paralleled to supply a
maximum current up to 40A.TH1775 permits high frequency measurement up to 1 MHz and
can be directly controlled by TH2816A, TH2817A, TH2818 and TH2819. TH1773/TH1775 with
its low additional error, wide frequency response range and sweep output function is widely
used in DC biased inductance measurement. TH1775 also provides a perfect solution
for magnetic material analysis.
