Electronics Power Supply / Management powerMEAN WELL RST-7K5(7,500W) and RST-15K(15,000W) three-phase four-wire ac input power supplies deliver a 95% high efficiency design and the maximum parallel output power up to 30kW. Three different dc output models are provided, including 115V, 230V and 380V, which serve various industries, such as automatic industrial equipment, charging energy storage systems, centralized bus power, and many other applications. The output voltage and current are programmable, while the output voltage adjustment can cover form 1% to 120%. Various built-in monitoring signals are provided, such as over temperature alarm, dc-OK, fan fail alarm, ac fail alarm functions, which allow users to quickly control and integrate system equipment. Models are able to operate in a wide temperature range of -30~ +45oC under full load conditions.
