FJ-10 DC Voltage Divider Product Introduction
The FJ-10 DC Voltage Divider is a precision measurement instrument utilizing resistance voltage division principle with wound resistor chains. It features four selectable ratios (×10, ×100, ×200, ×500) to extend the measurement range of DC potentiometers or serve as a standalone divider in DC circuits below 600V. The device maintains 6mA rated current with ±0.01% or ±0.02% ratio accuracy under 20±3℃ ambient temperature. Its wound resistors employ alloy materials with minimized thermal drift, ensuring stability during continuous operation. The compact unit (260×195×130mm) adopts fully insulated construction capable of withstanding 1000V AC for 1 minute, while providing 1000MΩ isolation resistance. Suitable for laboratory and industrial applications, it offers reliable performance within 10-30℃ operating temperature and ≤80% humidity conditions without requiring active cooling. The 3kg lightweight design facilitates portable usage. 236
產(chǎn)品技術(shù)特點(diǎn)
該產(chǎn)品采用定阻輸入式結(jié)構(gòu)設(shè)計，通過多只精密電阻元件構(gòu)成串聯(lián)分壓電路，在×10倍率下可將測量量程提升10倍。分壓箱內(nèi)部布局合理，操作接口簡潔，采用接線柱換接方式切換倍率。產(chǎn)品在20±3℃標(biāo)準(zhǔn)環(huán)境下，當(dāng)工作電壓不超過額定值時，倍率相對誤差嚴(yán)格控制在標(biāo)稱范圍內(nèi)。為適應(yīng)不同應(yīng)用場景，制造商可提供特殊參數(shù)定制服務(wù)。產(chǎn)品外殼采用工程材料制造，具有優(yōu)良的機(jī)械強(qiáng)度和散熱性能，確保長時間工作的穩(wěn)定性。1512
