FMT42普通型十進(jìn)電感箱
產(chǎn)品概述
FMT42普通型十進(jìn)電感箱是一款專為交流電路設(shè)計(jì)的精密可調(diào)電感設(shè)備，適用于高校實(shí)驗(yàn)室、科研機(jī)構(gòu)及工業(yè)應(yīng)用場(chǎng)景。該產(chǎn)品采用多盤步進(jìn)式結(jié)構(gòu)，通過十進(jìn)位開關(guān)實(shí)現(xiàn)電感值的精確調(diào)節(jié)，可調(diào)范圍為(0～10)×(1+10+100+1000)mH，最小步進(jìn)1mH，最大電感值達(dá)11110mH。其核心部件采用耐高溫絕緣骨架繞制，確保電感穩(wěn)定性，同時(shí)配備紅黑雙色接線柱便于串并聯(lián)組合使用。產(chǎn)品工作頻率為1kHz±20Hz，額定電流1.0A（低頻段）/0.015A（高頻段），在20±5℃環(huán)境溫度下可保持穩(wěn)定性能。箱體尺寸為580×140×140mm，重量約4kg，黑色耐磨防水漆面設(shè)計(jì)兼顧耐用性與美觀性。135
技術(shù)特點(diǎn)
該電感箱采用四組步進(jìn)盤組合設(shè)計(jì)，每組步進(jìn)盤可獨(dú)立使用或串聯(lián)組合，實(shí)現(xiàn)1mH至11.11H的寬范圍調(diào)節(jié)。內(nèi)部電感線圈選用高穩(wěn)定性材料繞制，配合精密十進(jìn)開關(guān)，確保調(diào)節(jié)過程中接觸電阻極小且重復(fù)性好。產(chǎn)品特別設(shè)計(jì)了磁屏蔽結(jié)構(gòu)，可減少周圍鐵磁物質(zhì)對(duì)測(cè)量精度的影響。使用時(shí)可自由切換不同量程，通過改變相鄰開關(guān)接線柱的連接方式實(shí)現(xiàn)電感值的疊加或獨(dú)立輸出。箱體底部采用非金屬絕緣底座，避免金屬接觸導(dǎo)致的渦流損耗，頂部?jī)?nèi)嵌搬運(yùn)把手提升操作便捷性。61220
典型應(yīng)用
FMT42電感箱廣泛應(yīng)用于交流電橋平衡、LCR諧振電路調(diào)試、阻抗匹配網(wǎng)絡(luò)構(gòu)建等場(chǎng)景。在高校電工實(shí)驗(yàn)中，可用于演示一階/二階電路響應(yīng)、功率因數(shù)校正、濾波器設(shè)計(jì)等教學(xué)項(xiàng)目；在工業(yè)領(lǐng)域，可作為可變標(biāo)準(zhǔn)電感器用于設(shè)備校準(zhǔn)。其多盤獨(dú)立接線設(shè)計(jì)支持靈活組合，既能滿足基礎(chǔ)實(shí)驗(yàn)的單量程需求，也可通過串并聯(lián)實(shí)現(xiàn)更寬范圍的精密調(diào)節(jié)。產(chǎn)品特別適合需要頻繁改變電感參數(shù)的研發(fā)場(chǎng)景，如無(wú)線充電系統(tǒng)優(yōu)化、變壓器特性研究等。2517
Product Overview
The FMT42 Decade Inductance Box is a precision adjustable inductor designed for AC circuits, featuring four-decade switching ranges from 1mH to 11.11H. Its robust construction with high-temperature-resistant insulation framework ensures stable inductance values under 1kHz±20Hz operating frequency. The unit provides 0.5% basic accuracy with color-coded terminals for series/parallel configurations, housed in a compact 580×140×140mm enclosure weighing approximately 4kg. Ideal for educational labs and R&D applications requiring variable inductive loads.3612
Key Features
This inductance box incorporates four independent decade dials with 1mH resolution, allowing flexible combination through front-panel terminals. The magnetically shielded design minimizes external interference while the non-conductive base prevents eddy current losses. Each dial maintains consistent contact resistance below 50mΩ during adjustment, supported by durable switch mechanisms rated for 10,000 operations. The top-mounted handle and side-mounted terminals facilitate easy integration into experimental setups. Operating temperature range covers -10°C to +40°C with ≤80% relative humidity.20617
Typical Applications
Widely adopted in university laboratories for demonstrating RLC circuit characteristics, impedance transformation, and filter design principles. Serves as essential equipment for AC bridge measurements, resonant frequency testing, and magnetic component research. The modular design enables customized inductance networks for power electronics development, including wireless power transfer optimization and transformer simulation. Its educational-friendly interface supports hands-on learning of electromagnetic theory fundamentals.5212
