Rack system puts 3kW front end in 1U

Industrial standard 19in rack system combines up to three hot-swappable units for a total power rating of up to 3000W in a single rack.New from Sunpower UK, the RCP Series targets the growing 1U low-profile 19in rack application market. This industrial standard 19in rack system combines up to three hot-swappable RCP-1000 units for a total power rating of up to 3000W in a single rack. Featuring active power factor correction (PFC) and 10.67W/in3 power density, RCP-1000 series can provide its rated output power even at 100V AC input because of its high efficiency design.

Three output voltage levels can be selected to give 12V/180A, 24V/120A or 48V/63A of front-end power.

The RCP-1000 also has built-in trimming function so that the output voltage can be adjusted between 90% and 110% rated value by simply adding external resistors.

This can provide users great flexibility in the design of their end system.

Besides the standard functions of remote sense, remote on/off control, 5V/0.3A auxiliary output, AC OK and DC OK signals, the RCP-1000 series also has built-in ORing diodes and Postronic connectors so that high reliable hot-swap and redundant operation can be ensured to provide users with a worry free power source.

The optional I2C interface can also offer important information on the PSU if online monitoring is required.

AC input fail, output power good/fail, temperature warning, overtemperature protection, fan fail warning signals along with the value of output voltage, output current, and internal temperature of the PSU can be monitored easily through the I2C databus.

Applications include use as a general-purpose front-end power system, sever, instrumentation, telecomms and datacomms where space is limited and 1U height is required.
