    Product Overview

    The SHR5E is a miniature digital soft starter specifically designed for three-phase small squirrel-cage motors. It can flexibly achieve soft starting and soft stopping, and both the soft starting and soft stopping processes are adjustable. The initial voltage (initial torque) during soft starting has multiple gear options.

    In this way, the impact of current and mechanical torque during the motor starting process is greatly reduced, protecting the safety of the motor equipment and the power supply network. It can be widely applied to various small motor devices, such as in the control systems of industrial and commercial air conditioners, refrigerators, freezers, water pumps, etc.

    This enables users to lower the requirements for the quality of the power supply network, reduce the burden on the power grid, and extend the service life of the equipment.

    Main features

    • It has a small, compact and sturdy structure, facilitating integration into the control system.
    • The DIN rail groove base enables easy installation and fixation. Parameters are adjusted through a centralized knob, featuring simple and intuitive operation.
    • With LED indicators, the power supply, operating status and fault analysis are clear at a glance.
    • The soft-start and soft-stop times are adjustable, and there are multiple options for the initial soft-start voltage.
    • It is equipped with a built-in bypass contactor, which reduces losses and extends the service life of the equipment.
