FMT23普通型十進(jìn)電感箱
產(chǎn)品概述
FMT23普通型十進(jìn)電感箱是一款專為高校實(shí)驗(yàn)室、科研單位及工業(yè)應(yīng)用設(shè)計(jì)的精密電感調(diào)節(jié)設(shè)備，采用多盤十進(jìn)式結(jié)構(gòu)，可靈活實(shí)現(xiàn)電感的步進(jìn)調(diào)節(jié)。該產(chǎn)品通過耐高溫絕緣骨架繞制電感線圈，結(jié)合優(yōu)質(zhì)十進(jìn)開關(guān)，確保電感值穩(wěn)定可靠。其核心功能是為交流電路提供可變標(biāo)準(zhǔn)電感，適用于濾波、諧振電路、阻抗變換及交流電橋等場(chǎng)景。產(chǎn)品采用模塊化設(shè)計(jì)，每個(gè)步進(jìn)盤均獨(dú)立引出接線柱，支持串聯(lián)或并聯(lián)使用，滿足多樣化實(shí)驗(yàn)需求。56
技術(shù)特點(diǎn)
FMT23電感箱最小步進(jìn)為100mH，最大電感值為11000mH（即11H），可調(diào)范圍為(0～10)×(100+1000)mH，準(zhǔn)確度達(dá)0.5%。額定工作電流為0.08A/0.015A（分檔設(shè)計(jì)），適配不同功率的電路實(shí)驗(yàn)。產(chǎn)品外殼采用堅(jiān)固絕緣材料，內(nèi)部布局合理，減少外部磁場(chǎng)干擾。尺寸為450×140×140mm（三開關(guān)組成），重量約4kg，便于搬運(yùn)和固定安裝。使用時(shí)應(yīng)避免置于金屬表面或強(qiáng)磁性環(huán)境中，以保障測(cè)量精度。1219
應(yīng)用場(chǎng)景
本產(chǎn)品特別適合高校電工電子實(shí)驗(yàn)，如一階/二階電路響應(yīng)測(cè)試、功率因數(shù)提升、交流參數(shù)測(cè)定等教學(xué)演示。在工業(yè)領(lǐng)域，可用于設(shè)備調(diào)試中的阻抗匹配或高頻電路設(shè)計(jì)。用戶可通過連接不同顏色接線柱（紅黑區(qū)分同名端）靈活組合電感值，操作簡(jiǎn)潔直觀。產(chǎn)品推薦在溫度20±5℃、濕度≤80%的環(huán)境下使用，工作頻率建議為1kHz±20Hz，以確保最佳性能。3616
Product Overview
The FMT23 Decade Inductance Box (Standard Type) is a precision adjustable inductance device designed for university laboratories, research institutes, and industrial applications. Featuring a multi-dial decade switching system, it enables stepwise inductance adjustment with high stability. The inductance coils are wound on high-temperature-resistant insulated frames, paired with durable decade switches to ensure consistent performance. Its primary function is to serve as a variable standard inductor in AC circuits, ideal for applications like filtering, resonant circuits, impedance transformation, and AC bridges. Modular design allows independent terminal connections for each decade, supporting series or parallel configurations. 56
Key Specifications
With a minimum step of 100mH and maximum inductance of 11000mH (11H), the FMT23 offers adjustable ranges of (0～10)×(100+1000)mH at 0.5% accuracy. Rated currents are 0.08A/0.015A (dual-range), suitable for low-to-medium power experiments. The robust insulated enclosure minimizes external magnetic interference. Compact dimensions (450×140×140mm for 3-switch version) and 4kg weight ensure portability. Avoid placement on metal surfaces or near strong magnetic fields during operation. 1219
Typical Applications
This product excels in educational settings for demonstrations such as circuit transient analysis or power factor correction. Industrial uses include impedance matching in equipment calibration. Users can combine inductance values via color-coded terminals (red/black for polarity), with intuitive operation. Recommended operating conditions: ambient temperature 20±5°C, humidity ≤80%, and frequency 1kHz±20Hz for optimal results. 3616
