FMT50普通型十进电感箱
产品概述
FMT50普通型十进电感箱是一款专为高校实验、科研及工业应用设计的精密电感调节装置。该产品采用十进式步进调节结构，可提供(0～10)×(0.01+0.1+1+10+100)mH的宽范围电感值调节，满足多样化的电路实验需求。其核心功能是通过多盘组合实现电感值的精确控制，适用于交流电路中的滤波器设计、阻抗变换和谐振电路等场景。产品采用耐高温、绝缘性能优异的材料制成骨架，确保电感稳定性，同时通过红黑双色接线柱标识同名端，便于用户快速连接与调试。1919
技术特点
FMT50由五只步进盘组成，最大电感值为11111.0mH，最小步进0.1mH，调节精度高。外型尺寸为450×250×140mm，采用非金属底座设计以减少铁磁性干扰。工作频率推荐1kHz±20Hz正弦波环境，额定电流为1.5A（最小步进盘）至0.015A（最大步进盘），用户需根据实际需求选择工作电流以避免过载。产品支持多盘独立使用或串联组合，灵活性高，且每个步进盘均经过人工老化与自然老化处理，确保长期稳定性。81123
应用场景
FMT50广泛应用于电工学教学实验，如一阶/二阶电路响应测试、功率因数提升实验等。在工业领域，可作为可变标准电感器用于交流电桥校准或阻抗匹配。其模块化设计允许用户根据实验复杂度自由扩展，例如在谐振电路中实现精确频率调谐。使用时需注意避免金属接触底座，并尽量减少引线包围面积以降低误差。产品适用于20±5℃、相对湿度80%以下的环境，存放时需保持旋钮朝上以保护内部结构。21416
英文介绍 (Product Overview)
The FMT50 Decade Inductance Box is a precision instrument designed for educational and industrial applications, featuring a decade-stepping mechanism with adjustable range of (0～10)×(0.01+0.1+1+10+100)mH. Its multi-dial design allows independent or combined use of five inductance steps, achieving a maximum inductance of 11111.0mH and minimum increment of 0.1mH. The non-metallic base minimizes magnetic interference, while color-coded terminals (red/black) simplify circuit connections. Ideal for AC circuit experiments like filtering and impedance transformation, it operates optimally at 1kHz±20Hz sinusoidal waveforms with current ratings from 1.5A to 0.015A per dial. The compact dimensions (450×250×140mm) and modular structure enhance portability and adaptability for diverse experimental setups.31220
Key Features
Constructed with high-temperature-resistant insulation materials, the FMT50 ensures stable inductance values under prolonged use. Each dial undergoes rigorous aging processes (both artificial and natural) to guarantee long-term reliability. The product supports flexible configurations—users may isolate single dials or cascade multiple units for extended ranges. Environmental recommendations include operation within 20±5℃ and humidity below 80%, with storage orientation (knob-up) to prevent mechanical deformation. Its applications span from university labs for teaching resonance phenomena to industrial settings requiring tunable reference inductors.91522
Usage Notes
When integrating the FMT50 into circuits, avoid placing it near ferromagnetic materials or metal surfaces to prevent measurement deviations. For multi-dial setups, limit maximum current based on the highest-range dial’s rating (e.g., 0.015A for 1000mH steps). The device’s open-frame design facilitates maintenance, though direct exposure to dust or moisture should be avoided. Educational users benefit from its compatibility with standard breadboards and transparent circuit visualization, while industrial adopters value its repeatability in calibration workflows.172124
