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.

Primary Current Injection Testers
Primary Current Injection Tester is designed for testing protective relay and circuit breakers and also testing the turns ratio of current transformers at high variable currents. A test current is injected into the primary side of a system to determine how the system behaves at particular levels of current. This test makes it possible to determine whether the relay will trip and how long the current needs to flow before the trip is initiated.

Foerster Instruments, Incorporated
The DEFECTOMAT systems by FOERSTER were specially developed for quality testing and process monitoring of long products. From hot testing to all bright steel processing steps, the surfaces of semi-finished products made from austenitic, (non) ferromagnetic metals can be tested for defects. The DEFECTOMAT systems operate in a contactless and non-destructive manner in accordance with the eddy current method and are used for detecting short defects, such as holes or localized defects and transverse defects. The systems detect defective materials fully automatically and reliably. Defects can be marked, classified, and automatically discarded. the test speed of up to 150 m/s facilitates 100% testing, even at high production speeds. The systems benefit from low operating costs and frugal energy consumption as well as low maintenance costs, few wear parts, and low use of materials.
