Quasi Square Wave Constant Voltage Transformers
-
Osborne Quasi Square Wave Constant Voltage Transformers are used to regulate output voltages for applications that have varying input voltages. When used with a rectifier conversion circuit, these units provide an elegant design approach to voltage regulation. Osborne achieves this innovative approach by partnering the constant voltage transformer with an auxiliary resonant capacitor winding. The result is a unique (though time honored) technology that offers reliability, performance, and cost advantages over other styles of voltage regulation.

DC Bias Current Power Supply
TH1775
-
Shenzhen Chuangxin Instruments Co., Ltd.
TH1775 is a DC Bias Current Source (or DC Magnetization Current Source) 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 ±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.
