UC1610 DC Bias Current Source
The UC1610 / UC1620 DC Bias Current Source (DC Magnetized Power Supply) is designed for inductance and transformer coil inductance measurement with DC bias superposition. It provides stable DC current with minimal influence on inductance measurement and wide frequency response, making it ideal for use with high-frequency LCR meters.
Available Models
- UC1610: ±10A DC Bias Current
- UC1620: ±20A DC Bias Current
Brief Introduction
UC1610/UC1620 DC Bias Current Sources are microprocessor-controlled instruments using automatic current and balance principles to achieve stable AC/DC superposition. They support forward and reverse constant current output and provide low additional error with enhanced frequency response. These features greatly expand the application range for magnetic core and inductor bias testing.
The instruments support direct control by UC2868A / UC2858A / UC2878 / UC2876 LCR meters and multi-point current scanning, offering an efficient solution for magnetic material analysis.
