1、概述
u211B 是一块电动机调速电路，通过监测交流电源的相位来输出控制信号。u211B
内部集成了一个频率/ 电压转换器和一个放大器形成一个转速控制的闭环系统，可应用在
需要稳定转速的调速电机中。除此之外，u211B 还集成了负载限制、电源检测和软启
动等功能，可以实现交流电机控制系统。其特点如下：
● 静态电流小（≤3mA ）
● 内置频压（frequency to voltage ）转换电路
● 平衡的负载限制特性
● 优化的软启动功能
● 转速监测、短路保护
● 自动再触发功能
● 触发脉冲典型值 155mA
● 电压和电流的同步监测
● 内置电源监测模块
● 封装形式：SOP16

| | Seller(陈宝玲(baobao)) Reply: 1. Overview
U211B is a motor speed control circuit that outputs control signals by monitoring the phase of AC power supply. u211B
A frequency/voltage converter and an amplifier are integrated internally to form a closed-loop system of speed control, which can be applied to
In the speed-regulating motor that needs stable speed. In addition, u211B also integrates load limit, power detection and soft start
It can realize the AC motor control system. Its characteristics are as follows:
● Low static current (≤ 3mA)
● Built-in frequency to voltage conversion circuit
● Balanced load limiting characteristics
● Optimized soft start function
● Speed monitoring and short circuit protection
● Automatic re-trigger function
● Typical value of trigger pulse 155mA
● Synchronous monitoring of voltage and current
● Built-in power monitoring module
● Packaging form: SOP16 |
