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
