WJ-THREE PHASE THYRISTOR SWITCHES FOR CAPACITORS (STS)【FOR POWER FACTOR BANK USE ONLY】

Model: WJ3PSZT

Booth No: S1211

Characteristic

The products incorporated with automatic power factor regulator to switching each capacitor steps on and off. The built-in
control unit of turn-on at zero voltage across the switch and turn-off at zero current eliminates the switching transient,

avoids inrush current or voltage, and reduces interference in electronic equipment supplied by the same power line.

This controller is 3 phaseswith 3 sets SCR (Silicon-controlled thyristor)for powerswitching controll.

This controller has the protection of phase loss, fuse broke, and overheat, etc.; and also offer output connection for

abnormal condition happened of system’s emergency use.

Open-circuit indicators for each phase fuses and abnormal output contacts for emergency control of system.

Small size, good heating dissipation. Built-in fast speed fuses for semi-conductor secure on short-circuit of load.

With temperature controlled cooling fans, the fans run when temperature is 55℃ on the radiator, and stop when temperature is less than 45℃ on the radiator. The design can extend 2 to 3 times of the fan's life.

With CE, IEC60158-2, EN61000-6-4, EN61000-6-2 certificated.
