1. Intro


Developments in the fields of electronics and optics led to computer and communications technology; research on atomic clocks and ultra-precision spectroscopy eventually led to the birth of satellite positioning systems. Physical science research drives long-term economic development by continuously outputting technological innovation.

This essay mainly talks about application of ultra-stable constant current source as excitation power supply in physics research, and briefly introduces TUNKIA’s cutting-edge product: TH1000 ultra-stable precision current source.

TUNKIA’s complete electrical traceability system provides strong technical support for the function and quality of its constant current sources.

    TUNKIA TH1000 Ultra-stable Precision Current Source is also characterized by:

    • High Stability: The current source is equipped with a wide-band current comparator for current measurement and control, ensuring the stability and accuracy of the output under test conditions.

    • Protection Modes: open circuit protection, overload protection.

    • Efficient Testing: Typical value of rise time < 10 ms, typical value of establishment time < 20 ms.

    • Low Ripple Coefficient: The constant current output ripple coefficient is less than 0.001% (<5 kHz).
