2026-6-17 16:19:33

Model meaning

The model of this soft starter is set with reference to asynchronous motors such as Y and YZ, and the typical current value corresponds to the Y series 4-pole motor.

Structure and Function
The composition of SRMR5 intelligent soft starter is shown in Figure 1. The main circuit is composed of directly anti parallel thyristors (or thyristor modules), and the transformer detects the motor current. The control circuit uses a microcontroller as the control core, and parameter settings and status display are completed using buttons and digital tubes. The structure is advanced, novel, simple, easy to operate, and practical.
In addition, it is equipped with relatively complete control input terminals and status output terminals: the R, S, and T input terminals are connected to a 3-phase AC380V power supply, and the output terminals U, V, and W are connected to the motor. The A angle of the thyristor is controlled to linearly increase the voltage output from the thyristor to the motor to the rated value, that is, the so-called slope to the top. The motor accelerates to the rated speed, completes soft start, and sends a bypass signal to make the bypass contactor close and switch to bypass operation, while fault detection still protects the motor.

2026-6-13 18:46:34

The QX3 series star delta starter (hereinafter referred to as the starter) is mainly used for starting and stopping star delta switching of three-phase squirrel cage induction motors with AC 50 or 60HZ, voltage up to 500V, and capacity up to 30KW. During the starting process, the starter can automatically switch the star connected stator winding of the controlled motor to a delta connected starter through a time relay. The starter is equipped with a thermal relay as overload protection, and its contactor inductance also serves as voltage loss protection when the grid voltage disappears.

[Cam starter]QS5 series cam starter

2026-5-26 19:57:56

The QS5 cam starter is suitable for AC three-phase asynchronous motors with a voltage of 500 volts, a capacity of up to 18.5 horsepower, and a frequency of 50-60Hz. It can be used for direct starting in forward or reverse direction, stopping in use, and switching between two circuits.
The main body of this type of cam switch is a rubberwood seat, and all other components are installed in the rubberwood seat, resulting in a small volume and compact structure. This relationship utilizes wheels with different outer edge shapes to push the contact points to complete the opening and closing actions of the circuit, and uses pure silver material as the contact points. Ensure good electrical contact and chemical stability. For operational safety, all live parts are protected with aesthetically pleasing aluminum shells.
The product complies with standards such as VDE0660 and GB/T14048.1.
