Tonghui TH1773 DC Bias Current Source

Availability: In stock


Quick Overview

TH1773, a DC Bias Current Source (or DC Magnetization Current Source), is mainly used 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 ±10A. With its low additional error, wide frequency response range and sweep output function, the meter is widely used in DC biased inductance measurement. It also provides a perfect solution for magnetic material analysis.
