The world leader in standard power supply — MEAN WELL, in order to fulfill high-power industrial applications, such as high-voltage charging systems, centralized bus power and other new applications. MEAN WELL has launched its latest three-phase four-wire AC input RST-7K5(7,500W) and RST-15K(15,000W) power supply with 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. In addition, the output voltage and current are programmable, especially, the output voltage adjustment can cover form 1% to 120%. Besides, 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. Also, while applications in many industrial fields may be exposed to various harsh environments, the models are able to operate in a wide temperature range of -30~ +45oC under full load conditions. RST series also provides a choice of two different cooling methods, the forced-air cooling type with built-in fans (RST-7K5/15K) and the water-cooling type (RST-7K5L), either of which can be easily selected according to the characteristics of the equipment or the environment.
In addition to the above features, RST-7K5/15K series are in line with the latest version of the EN/UL62368-1 international safety standards. Also, the mechanism is miniaturized (<2U), and can be installed with a standard 19-inch rack cabinet. It is the best choice of standard power supply for a wide variety of industries equipment with good cost-efficiency and high reliable features. Finally, MEAN WELL's high voltage DC (HVDC)output series includes both three-phase and single-phase series. Please refer to the introduction of high-voltage DC output (HVDC) series in MEAN WELL's Virtual Expo.
