2U redundant PSU with active power factor correction

28 August 2002 Power Electronics / Power Management

Sunpower Technology's new 2U Mini Redundant power supply with active power factor correction is rated 450+450 W and has a universal full range AC input. The SPR-2450P6 also meets international safety standards.

Measuring 106 x 315 x 83,5 mm the PSU has active power factor correction of more than 0,95, a current share function (+3,3 V, +5 V, +12 V) and over-load, over-voltage and short circuit protection. Total combined power on +3,3 V and +5 V are 300 W maximum; on -5 V and -12 V are 12 W max continuously. For single module total combined is 450 W; for dual module are 700 W maximum continuously.

It is rated for operation over temperature range 0-70°C and for use in 20%-85% relative humidity. MTBF is over 89 000 hours.
