Mean Well RST-7K5-115L High Power AC/DC Power Supply 7475W, 3 Phase Input, 115V Output, Water Cooling 65A

The RST-7K5-115L is a high power AC/DC supply rated for 7475W output. It provides 115V DC nominal output with 65A rated current. This model is designed for 3-phase AC input systems and is built for applications that need substantial regulated DC power from a single enclosure.

This model fits industrial and OEM systems that need a high power 115V DC source, especially where centralized DC power is preferred over multiple smaller supplies. Its 7475W capacity, programmable output behavior, and support for parallel current sharing make it relevant for demanding equipment, test systems, and large control platforms. Buyers evaluating high-load B2B projects will usually consider it where both power density and output control matter.

Yes. Mean Well specifies active current sharing for up to 4 units, allowing total capacity up to 28.5KW in multi-unit systems. That makes this model a practical option for larger installations that may need scalable DC power without changing to a different platform.

The main difference is scale and control. This model delivers 7475W at 115V with 3-phase input support, programmable output voltage and constant current level, and selectable water or forced-air cooling. It is intended for substantially heavier-duty use than conventional single-phase or lower-wattage enclosed supplies.

The RST-7K5-115L is specified for operation from -30°C to 70°C, which supports demanding industrial environments when the system is designed around the unit's cooling method. Mean Well also lists selectable water cooling or forced-air cooling, giving more flexibility for high thermal load installations. For buyers comparing platforms, that combination is a key differentiator in continuous-duty applications.

Yes. This model includes programmable output voltage and programmable constant current level, with a wide voltage adjustment range of 1 to 120%. It also has built-in remote ON-OFF control and an alarm signal, which is useful for monitored industrial power systems.

Mean Well lists short circuit, overload, over voltage, over temperature, and fan fail protection for this model. The unit also carries a 5-year warranty, which is notable for a power supply in this output class. These features make it better aligned with long-service B2B equipment requirements than bare-bones high-power supplies.
