(1) Soft starter overload protection function: soft starter introduced the current control ring, so at any time to track the detection of motor current changes. By increasing the overload current setting and anti-time-limit control mode, the overload protection function is realized, so that when the motor is overloaded, the thyristor is switched off and the alarm signal is issued.
(2) Soft starter phase-loss protection function: when working, the soft starter at any time to detect the change of three-phase line current, once a break, you can make a phase-out protection reaction.
(3) Soft starter overheat protection function: through the soft starter internal thermal relay to detect the temperature of the thyristor radiator, once the heat sink temperature exceeds the allowable value automatically shut off the thyme tube, and send an alarm signal.
(4) Other functions: through the combination of electronic circuits, but also in the system to achieve a variety of interlocking protection.
Yueqing Winston Electric Co. , Ltd. is located in the electrical capital of Wenzhou, the company has been committed to AC motor soft starter sales, one after another to the market Winston WST series: R1, R2, R3, R4, WSTM and other high-performance high-performance low-voltage (380V, 440V, 660V, 1140V, 3300V, 6KV and 10KV) soft starter products, products are widely used in various fields at home and abroad, and won wide acclaim. The company has a perennial engaged in the soft starter industry elite team, the establishment of radiation throughout the country's logistics and service network.
