Zhengxi’s three-phase transformer converts 380V to 220V, 690V, 415V, 660V, and 480V, and is an industrial-grade device designed for multi-scenario power conversion, featuring high-precision voltage regulation, electrical isolation, and reliable protection performance. It adopts all-copper wire winding and epoxy resin vacuum casting process. The winding is completely encapsulated in a fiberglass body that has fireproof, moisture-proof, and corrosion-resistant characteristics, reducing energy consumption and improving heat dissipation efficiency. Through its multi-tap winding design, the output voltage can be flexibly adjusted to meet the power requirements of various equipment in the Bitcoin farm.
