TJSeries capacitor fast switching switch, suitable for capacitor fast switching switch for 0.4KV system power reactive power compensation, using thyristor module as switching device, pulse transformer trigger, advanced high-speed single-chip measurement algorithm, to ensure that the current conducts at the zero-crossing point It does not generate closing inrush current, and the response time is less than 20ms, which can effectively compensate the impact load. The built-in temperature protector and temperature control algorithm make the fan reasonable and safe to use.
