    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.

    Frequently Asked Questions

    What is the primary application of the SHR5E soft starter?
    The SHR5E is a miniature digital soft starter designed specifically for three-phase small squirrel-cage motors. It is widely used in control systems of industrial and commercial air conditioners, water pumps, refrigerators, and freezers.
    How does the SHR5E protect the motor and grid?
    By providing adjustable soft starting and soft stopping, it greatly reduces the impact of current and mechanical torque during the motor starting process. This protects the motor equipment and reduces the load burden on the power supply grid.
    What are the installation options for this soft starter?
    It features a compact design that supports dual installation methods: either via a standard 35mm DIN rail groove base or fixed directly with screws.
    Does it require an external bypass contactor?
    No, the SHR5E comes equipped with a built-in bypass contactor. This integration reduces electrical losses and significantly extends the service life of the equipment.
    What are the adjustable parameters of the SHR5E?
    Users can adjust the soft start time (1 to 20 seconds), soft stop time (0 to 20 seconds), and initial soft-start voltage (ranging from 40% to 70% Ue) using a centralized knob.
    What control voltages are supported?
    The unit supports two control voltage configurations: Option C (110 ~ 240VAC, 50/60Hz) and Option D (24VDC).
