应用运动产品扩大mily of STR Stepper Drives with two new ac-powered units for use in industrial applications powered by ac supply voltages. Offering the benefits of low noise, smooth motion, and high torque over wide speed ranges, the STRAC Stepper Drives bring high-performance motion control to basic step and direction applications. Units are ideal for larger motors and applications requiring maximum power.
像他们的DC驱动对应物一样，Strac步进驱动器具有高级微填充性能和电流控制，具有抗谐振，可改善运动平稳性和扭矩在较宽的速度范围内。单位以90至240 VAC的交流电源电压直接运行，直接导致至120或220 VAC线电压，以消除直流电源要求。驱动器内部将交流线电压转换为高直流总线电压，以最大的功率驱动大型踏板电动机。
Strac2在两种型号中可用，最多可2.2 A/相，而Strac8提供高达8.0 A/相。Str系列中的每个步进驱动器均以步骤和方向或脉冲/脉冲控制模式运行。通过移动位于驱动器盖下的跳线或通过前面板上的浸入开关来选择两种模式之间的选择很简单。即使命令脉冲是低分辨率的，每个驱动器将用1.8°踏步电动机（1/125步）驱动至25,000步/转速，这要归功于专有的台阶平滑滤波器。用户可以使用DIP或旋转开关设置驱动参数 - 包括电动机选择，电流和步骤分辨率。无需软件。
The STRAC Stepper Drives are UL Recognized, CE certified, and RoHS compliant. Applied Motion Products offers a full complement of NEMA 23 and 34 frame step motors optimized for use with these new ac-powered drives.
