產品技術特點
JZT4控制器采用電子式調速原理,通過測速發(fā)電機將電機轉速轉化為電壓信號反饋至調節(jié)器,形成閉環(huán)控制系統(tǒng)。調速過程中無需機械傳動部件,減少了維護需求。裝置支持手動精密調節(jié),轉速變化率≤2.5%,穩(wěn)速精度≤1%,可適應50-60Hz電網(wǎng)頻率。內部電路設計注重抗干擾能力,確保在復雜工業(yè)環(huán)境中穩(wěn)定運行。結構上采用底部進線方式,支持面板嵌入式或墻掛式安裝,塑殼密封設計有效防護油污和水漬。調試時需配合測速發(fā)電機校準轉速表指示值,并通過反饋電位器優(yōu)化高速運行性能。4713
Technical Features
The JZT4 employs electronic speed regulation technology, utilizing a tachogenerator to convert motor speed into voltage feedback for closed-loop control. This contactless design eliminates mechanical wear components. With ≤2.5% speed variation rate and ≤1% steady-state accuracy, it supports manual fine-tuning and adapts to 50-60Hz power supply. The robust circuit design ensures reliable operation in harsh industrial environments. The dust-tight plastic housing with bottom wiring entry allows both panel-mounted and wall-mounted installations. Initial setup involves tachogenerator calibration and feedback potentiometer adjustment for optimal high-speed performance. 4713
應用場景說明
本裝置特別適用于風機、泵類負載的節(jié)能調速,通過無級調節(jié)可降低設備能耗。在食品加工領域,能精確控制輸送帶速度匹配生產工藝;在造紙機械中,可協(xié)調多電機同步運行;在輕工生產線則用于調整加工設備的進給速率。使用時需注意環(huán)境溫度保持在-5℃~+40℃范圍,避免導電塵埃和腐蝕性氣體。操作人員應具備電工資質,確保斷電狀態(tài)下進行接線或維護。長期停用后建議進行電氣性能檢測,更換元件時需使用≤45W電烙鐵快速焊接以防損壞PCB。101417
Application Scenarios
Ideal for energy-saving speed regulation of fan and pump loads, the device reduces power consumption through stepless control. In food processing, it precisely adjusts conveyor speeds for production needs; in paper machinery, synchronizes multi-motor operations; and in light industry, regulates equipment feed rates. Operational environment should maintain -5℃~+40℃ without conductive dust or corrosive gases. Qualified electricians must perform wiring/maintenance under power-off conditions.
