恒星软启动器提供低成本的电机控制替代方案

SR22系列软启动器（有5A至40A尺寸）具有过电流的保护，并具有两个可DIN-RAIL可安装的框架尺寸（45mm和55mm）。基于微处理器的启动器的工作电压范围为208至460 VAC。易于配置，每个单元配备了三个电位仪，可调节启动和停止时间最多30秒，可调节的启动基座电压范围为30％至100％。需要单独的24VDC控制电压。

Ideal for applications such as pumps, blowers and conveyors, the SR22 series soft starters use thyristors for controlled reduced voltage motor starting and stopping, and then switch to internal contacts for efficient running at rated speed. When used instead of a line starter, Stellar soft starters provide smoother control resulting in less torque, less shock, and less electrical and mechanical stress.

两年质保,恒星软starters prices start at $145. To prolong the life of the soft starter, optional cooling fans are available starting at $45.
