High Frequency Welded Pipe Rectifier Cabinet

The mature three-phase full control technology is used to convert the three-phase power frequency AC power into DC power. The large-capacity filtering parameters are designed to form a more stable voltage source, and the unique protection circuit is used to supply power to the inverter unit. The circuit board achieves accurate and stable energy output, and at the same time, the various working environments of the equipment are detected by Siemens PLC, forming a complete protection system. The main features are:

a. Adopt mature three-phase fully-controlled rectifier bridge structure, use well-known high-quality thyristor device to form rectifier unit, adopt large-capacity filter design, and the output is stable and reliable.

b. The unique protection circuit design and fault chain design make the equipment suffer less impact when encountering abnormal conditions, reduce the risk of damage, and have a higher protection success rate.

c. It has various protection detection functions such as overvoltage, overcurrent, load short circuit, water temperature, water pressure, phase loss, power supply instability, etc., and provides eye-catching and direct guidance through plc and man-machine interface.

d. It has external function interfaces such as start-stop external control, power external control and fault alarm output.
