Product Introduction of RX7/118 Wide-range Precision Capacitance Box (English)
The RX7/118 wide-range precision capacitance box features a rotary decimal design with six adjustment knobs, providing precise capacitance control from 0 to 1000μF through (0~10)×(0.001+0.01+0.1+1+10+100)μF combinations. Its shielded enclosure minimizes external interference while maintaining stable performance in environments with temperatures between +10℃ to +35℃ and relative humidity of 30%-80%. The unit incorporates high-quality polystyrene or polypropylene film capacitors, achieving 1nF minimum increment steps. With 1-2 terminals for main connection and 0 terminal for shielding ground, this compact device (550×200×150mm) suits various applications including AC bridge circuits, phase-shifting networks, and capacitance meter calibration. The silver-copper composite switch contacts ensure reliable performance and extended service life. 3137
產(chǎn)品功能特點(diǎn)
該電容箱采用模塊化十進(jìn)開關(guān)組件設(shè)計(jì)，每組開關(guān)由多個(gè)并聯(lián)電容構(gòu)成1-10的步進(jìn)值，接觸點(diǎn)采用銀銅復(fù)合材料確保長(zhǎng)期穩(wěn)定性。電氣部分全部安裝在屏蔽機(jī)箱內(nèi)，有效隔離電磁干擾。使用時(shí)支持兩端或三端接入工作電路，用戶可根據(jù)實(shí)際需求選擇連接方式。產(chǎn)品在20℃±5℃環(huán)境、800-1000Hz工作頻率及50V有效值電壓條件下可達(dá)到較好的性能表現(xiàn)。為確保測(cè)量精度，建議在使用時(shí)考慮連接導(dǎo)線電容影響，并注意環(huán)境溫度和強(qiáng)電場(chǎng)的干擾因素。1137
Functional Highlights
This capacitance box employs modular decimal switches where each knob controls parallel-connected capacitors to achieve 1-10 step values. The sliding contacts use silver-copper alloy for oxidation resistance and consistent electrical performance. When connecting to circuits, users may adopt either two-terminal or three-terminal configuration depending on application requirements. For optimal performance, we recommend operating at 800-1000Hz frequency range while considering ambient temperature compensation and cable capacitance effects. The built-in discharge circuit allows safe operation by automatically discharging stored energy after adjustments. Its structural design focuses on reliability and ease of use, making it suitable for both laboratory and industrial calibration purposes. 3713
