3000A Three Phase Dry Type Rectifier ​​Transformer 400V To 14v With UL Certification

Summarization

The three-phase dry-type rectifier transformer is a crucial component of rectifier equipment, forming a rectifier circuit system with various rectifier devices. To convert AC power to DC power, the rectifier transformer first adjusts the voltage of the AC power grid to a specific size and number of phases. This adjusted AC voltage is then passed through a rectifier device, which converts it to DC power for use by DC drive equipment.
