调速电动机控制组合装置，DK-2B

产品概述

调速电动机控制组合装置DK-2B是一款专为电磁调速电动机（滑差电机）设计的精密控制设备，适用于工业领域中对电机转速进行宽范围无级调节的需求。该装置通过手动或自动信号输入（如4-20mA或0-10V）实现精准调速，调速范围可达120-1370转/分，并具备高稳定性与抗干扰能力。其核心功能包括转速显示、手动/自动切换及低速限制调节，适用于0.55-40KW功率的电机控制。

DK-2B采用电子式反馈系统，确保转速变化率≤2.5%，输出最大直流90V/5A，适配AC220V电源。其结构紧凑，操作面板集成转速表、校准电位器等，便于现场调试与监控。典型应用场景包括造纸、纺织、印刷等需要恒转矩控制的行业，能有效提升设备运行效率与工艺一致性。

The DK-2B Speed Control Combination Unit is a precision device designed for electromagnetic speed-regulating motors (slip motors), catering to industrial applications requiring wide-range stepless speed adjustment. It achieves accurate speed control via manual operation or automatic signal input (e.g., 4-20mA or 0-10V), with a speed range of 120-1370 RPM and high stability against interference. Core features include real-time speed display, manual/auto switching, and low-speed limit adjustment, compatible with motors of 0.55-40KW power.

Equipped with electronic feedback, the DK-2B maintains a speed variation rate ≤2.5%, delivering a maximum output of 90V DC/5A and operating on 220V AC. Its compact design integrates a control panel with a tachometer and calibration potentiometers for on-site tuning. Ideal for industries like papermaking, textiles, and printing, it enhances operational efficiency and process consistency in torque-sensitive applications.

技术特点

DK-2B控制器采用可控硅整流电路与单结晶体管触发技术，结合速度负反馈机制，确保调速平滑且响应迅速。内置保护功能如过压吸收电路（压敏电阻）和保险丝，提升设备安全性。其面板转速表支持校准，可匹配不同测速发电机信号，适应多样化工业环境。

The controller employs thyristor rectification and unijunction transistor triggering, coupled with speed negative feedback for smooth and responsive regulation. Built-in protections like overvoltage absorption (varistor) and fuses enhance safety. The calibrated tachometer accommodates various tachogenerator signals, ensuring adaptability across industrial scenarios.

应用优势

该装置显著降低人工干预需求，通过自动化信号接口（如DDZ-II调节器）实现多台电机同步或比例运行，适用于流水线集中控制。其模块化设计便于维护，且反馈电位器可微调机械特性硬度，优化负载适应性。

By supporting automated signals (e.g., DDZ-II regulators), the unit reduces manual intervention, enabling synchronized or proportional multi-motor control in production lines. Its modular design simplifies maintenance, while adjustable feedback potentiometers fine-tune mechanical rigidity for optimal load performance.
