【English Version】Product Introduction of ZX1M AC/DC Resistance Box
The ZX1M series AC/DC resistance box is a precision instrument specifically designed for electronic circuit debugging and equipment testing, suitable for various scenarios including laboratory research, industrial inspection, and educational experiments. Incorporating modular design principles, this product ensures fundamental functional stability while maintaining operational convenience and environmental adaptability.
Three core technical advantages define this equipment: Firstly, the innovatively designed resistance network structure supports a wide measurement range from 0.1Ω to 20MΩ, achieving 0.1% level adjustment accuracy through precision stepping knobs to meet precise resistance simulation requirements for various AC/DC circuits. Secondly, the specially configured thermal protection system adopts a multi-layer isolation structure combined with temperature compensation technology, ensuring stable electrical performance during continuous operation. Thirdly, the user-friendly interface features dual digital displays for simultaneous viewing of preset values and real-time parameters, with specially calibrated knob damping to enhance operational tactility and positioning accuracy.
The product structure utilizes an all-metal protective casing with special anti-oxidation surface treatment. Built-in shock-absorbing buffer layers effectively improve impact resistance. Input terminals adopt composite connector design compatible with banana plugs, alligator clips, and other connection methods, including an independent protective grounding port. To accommodate diverse application environments, dual installation solutions (portable and benchtop) have been developed, allowing users to select wall-mount brackets or desktop fixation according to site conditions.
Regarding safety performance, the equipment integrates an automatic overload cut-off device that instantaneously activates protection mechanisms upon detecting abnormal currents or excessive temperatures. All conductive components are insulated with industrial-grade materials, with critical interfaces protected by anti-misoperation covers. Through rigorous process control and multi-level quality verification procedures, the equipment ensures long-term reliability and stability during extended usage.
The product s compatibility extends to mainstream testing instruments, supporting voltage ranges from 12V to 600V. Clear scale markings and status indicator lights facilitate rapid parameter confirmation. Optimized internal wiring layout minimizes electromagnetic interference, while the modular component design simplifies maintenance procedures. This resistance box provides engineers and researchers with flexible and reliable resistance loading solutions for applications including circuit characteristic verification, equipment calibration, and system simulation testing.
