How to install the Japan AC power supply so that it can function as a protection switch?(1)

Drive module power supply
The frequency converter power supply is mainly used for the frequency conversion and speed regulation of the AC motor. The main circuit of the inverter power supply adopts the AC-DC-AC scheme. The power frequency power supply becomes a fixed DC voltage through a rectifier, and then a PWM high-frequency converter composed of high-power transistors or IGBTs inverts the DC voltage into an AC output with variable voltage and frequency. The output waveform of the power supply is similar to a sine wave. It is used to drive the AC asynchronous motor to realize stepless speed regulation.

How to install the Japan AC Marine boost voltage power supply so that it can function as a protection switch?

Since the air switch and the leakage switch do not have protective functions, when the Marine boost voltage power supply is abnormal, a large number of electrical equipment will be damaged. When these accidents occur, it is only necessary to disconnect the Marine boost voltage power supply when the Marine boost voltage power supply is abnormal, so as not to damage the electrical equipment.

Japan The three-phase AC power intelligent protector has major electrical fault protection functions such as overvoltage, low voltage, neutral wire disconnection, short circuit, phase loss/opening, etc., and has fault identification, fault indication, voltage before closing, neutral live wire reverse connection, Zero line disconnection, phase loss/phase failure detection, remote monitoring, online parameter modification and software upgrade functions.
