10kW DC power now available from a single AC/DC switching unit
Sunpower's new high-power enclosed Mean Well AC/DC RST-10000 switching power supply, delivering 10kW DC power from a single unit, is the well suited for high-power systems builders under pressure to design more functionality and greater power density into smaller areas. Its advantage as an efficient, high-power density resource is further enhanced as two units can easily be paralleled to provide 20kW total DC power. The product is a development from the well-established Mean Well RST-5000 5kW model.
The RST-10000 can accept a delta-connected three-wire three-phase 196 to 305V AC input. Alternatively, it can operate from a 4-wire "Y' connection delivering 340-530V AC. Three versions are currently available as standard, offering 24, 36 or 48V DC outputs, respectively. Output voltage for all versions can be trimmed between 20 per cent and 120 per cent of the nominal output by using a 1-6V DC external control signal. Another external control signal, of 1-5V DC, allows trimming of the output current between 20 per cent and 100 per cent of its nominal output value.
These units have a couple of powerful protection function modes. The first provides continuous constant current limiting to prevent overload damage, and the second offers constant current limiting with shutdown after 5 seconds' delay. Short circuit, over voltage and over temperature protections are also provided. International UL, CUL, TUV, CB and CE approvals are in place.
A built-in 12V 0.1A auxiliary output is provided; this can be used for remote On/Off control. Alarm signals report AC Fail, DC OK, Fan Fail and Over Temperature conditions. Remote Sense connections are also provided.
Sunpower's RST-10000 offers a high efficiency of 91 per cent, boosted by a built-in PFC function. A built-in fan with speed control function provides forced air cooling; this allows full load output in temperatures to 50degC ambient.
Andy Wall, CEO of Sunpower UK, comments: "With a power level previously unattainable from a single unit, Sunpower's Mean Well RST-10000 allows systems designers to achieve more compact and competitive power solutions for high-power applications such as automation equipment and machinery, industrial control systems, large-scale charging systems and laser cutting machines. Equally, they provide new possibilities for data processing environments such as data centres, cloud storage systems and central office telecommunications systems."
