Custom power phase converter with AC-DC-AC Factories, Exporter

Bangzhao Electric's BZT series power phase converters use an AC-DC-AC circuit structure to convert AC single-phase voltage into industrial three-phase voltage. Based on the US TI DSP28335 microprocessor and employing the Liuling IPM intelligent module, they offer simple maintenance, long life, and low losses. They utilize dual closed-loop control, fast response, and powerful protection features, enabling single-unit capacities up to 500kW.

Product Description

Product Feature
Wide voltage input 80-320VAC, special voltage can also be customized according to requirements, and it can adapt to the low working voltage of universal mains in all regions.
The output is industrial three-phase power, but it is economical because it is based on civil single-phase electricity billing.
The core components are imported devices. Using the sixth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency and stable performance, long service life, powerful protection functions, and convenient replacement and maintenance.
Using TI central processor DSP28335 chip from USA, the response speed is rapid and accurate, providing a stable and clean power supply for the load.
Humanized safety design: adopts isolation transformer design. The input and output are completely electrically isolated. Equipped with MCCB for convenient and safe installation. Fully enclosed live parts prevent children from getting an electric shock.
Output perfect protection function, with output over-voltage, overload, short circuit, over temperature, self-diagnosis protection and other protection.
LCD+LED display: shows input and output voltage, current, power consumption, fault display, convenient for customers to quickly find faults and guide maintenance.
The whole machine adopts a modular design, plug-in type design, easy maintenance, reducing the hidden costs of machine failure to repair.
The converter has the function of filtering the grid disturbance and interference, providing a more stable and pure power supply environment for the backend devices.
