The HY-PW series is an auto-range wide-range switching DC power supply with multi-stage cascade topology independently developed by Hangyu Power. It breaks the limitation of traditional rectangular output, covering full operating conditions of high voltage low current and low voltage high current in single unit. Single unit power ranges from 5kW to 15kW with compact 3U high power density rack. Master-slave parallel expansion without circulating current supports max 1.5MW total power, ideal for high-power steady-state testing of new energy high-voltage components, energy storage, charging piles and aerospace servo systems
