Product Detail

Product Tags

TC series capacitor fast switching switch is suitable for 0.4kV system power reactive power compensation. It adopts SCR module as switching device, pulse transformer trigger, advanced high-speed single-chip microcomputer measurement algorithm to ensure that the current is disconnected at zero crossing point, no switching inrush current is generated, and response time is less than 20ms, It can effectively compensate the impact load, built-in temperature protector and temperature control algorithm, so that the fan can be used reasonably and safely; the application of over-current protection can prevent the over-current risk caused by system resonance and other reasons.
