Obtained Type Test Report for Parallel DC Power Supply System

On February 28, 2026, Zenitek Intelligent obtained the Type Test Report for the ZDZNGZDWB Parallel DC Power Supply System.

The testing was conducted by the National Quality Inspection and Testing Center for Power Transmission and Distribution Safety Control Equipment and the Experimental Verification Center of State Grid Electric Power Research Institute Co., Ltd., which are China-accredited and internationally mutually recognized testing institutions with CNAS and ILACMRA accreditation.

The parallel DC power supply system adopts a modular DC power supply architecture with the DC bus as the core of power convergence. Multiple independent power units — including AC/DC rectifier modules, energy storage battery packs, and DC/DC conversion units — are connected to the same DC bus in parallel with the same polarity to jointly supply power to loads.

Its core features include multi-unit redundant parallel operation, autonomous current sharing control, rapid fault isolation, and uninterrupted power supply under all operating conditions. As a new generation of highly reliable power supply solution, it replaces the traditional series battery-based DC power supply system and has been widely applied on a large scale in key fields such as electric power, telecommunications, and data centers.
