FMT400 Decade Inductance Box Product Introduction (English)
The FMT400 standard decade inductance box is a adjustable inductance device composed of multiple decimal switches, designed for AC circuit regulation in laboratories and industrial applications. Featuring a high-temperature-resistant plastic frame with excellent insulation properties, it ensures stable inductance values. Key specifications include: a wide range of 0.001mH to 11.110mH achieved through four decade dials configured as (0～10)×(0.001+0.01+0.1+1)mH, with a minimum step increment of 0.001mH. The product emphasizes operational convenience with dual-color (red/black) binding posts for each decade dial, allowing series/parallel connections or independent usage. Recommended operating conditions are 20±5℃ ambient temperature and below 80% humidity, with rated current of 2.2A/1.0A (by ranges). Its compact metal enclosure (approx. 260×195×130mm) adopts an upward-knob placement design to enhance durability. Typical applications encompass filter circuits, resonance experiments, impedance transformation, and AC parameter measurement, making it particularly suitable for electrical engineering education and fundamental research in scientific institutions. 201813
设计特点与优势
该电感箱采用模块化十进盘结构，每个盘可独立使用或组合调节，提供灵活的电路适配能力。骨架材料选用特殊工程塑料，既减轻重量（整机约3-4kg）又避免金属骨架的磁滞损耗问题。内部绕组工艺注重降低直流电阻，减少发热对精度的影响。面板布局清晰，旋钮档位标识明确，支持快速精确调节。箱体底部设有防滑垫设计，避免实验过程中移位。产品适用于50Hz-1kHz频率范围的交流电路，满足教学演示中滤波、相位调节、谐波分析等多样化需求。1219
Design Features
Modular decade dial structure allows individual or combined operation, delivering flexible circuit adaptation. The special engineering plastic frame reduces weight (total ~3-4kg) while eliminating magnetic hysteresis losses common in metal frames. Winding technology minimizes DC resistance to mitigate thermal drift. Clear panel markings and detent-positioned knobs enable rapid precision adjustments. Non-slip feet enhance stability during operation. Compatible with AC circuits from 50Hz to 1kHz, it supports diverse educational demonstrations including filtering, phase adjustment, and harmonic analysis. 1119
