SY-TS series

SY-TS series SCR
Low voltage power network capacitor switching

1、Application

SY-TS series switch is in three-phase systems used to switch capacitors, and other switching device compared to the, the switch has no inrush current during switching, without exposure to noise and high switching frequency. These advantages are achieved by triggering circuits, thyristor, diode, and some auxiliary circuits. The switch is suitable for the occasion which changes the load quickly..
For example:

●The medium frequency induction furnace

●The hoist and crane

●A welder based factories

2、Unit

  The main switching device has bidirectional SCR, trigger circuit, absorption circuit, heat sink, and cooling device and other components.. The trigger circuit judges whether the output control signal (DC12V) is at zero voltage or zero, and the thyristor can turn off or lead.. The trigger circuit can reliably guarantee the output of the control signal, the good heat conduction function of the heat sink, and the addition of the cooling fan, greatly improve the cooling effect of the switch.. The device has the built-in over temperature protection switch, and the temperature switch of the automatic operation of the blower, thus providing good condition for safe operation..

3、Main features

●The zero crossing switching, no inrush current, will not cause voltage flicker;

●The photoelectric isolation, strong anti-interference ability, fast response speed, (20ms);

●Integration, small volume, convenient installation;

●LED display signal switching state;

●The built-in cooling fan, automatic control fan start and stop;

●The built-in temperature (80 DEG C) protection;

●The whole cast structure, durable;

●Contact type safety connection technology, IP30;

●The operation, no noise, no mechanical wear, long service life.
