 The unit comes with dc voltage outputs and maximum loads of 3.3 V/24 A, 5 V/24 A, quadruple 12 V/16 A, –12 V/0.5 A, and 5 Vsb/3 A for standby purposes. A standard output cableset includes a 24-pin ATX motherboard, PCI-E, four-pin Molex, and SATA power connectors. The power supply’s earth leakage current is 300-µA maximum @ 264 Vac, 63 Hz.

Additional features include a 90 to 264-Vac universal input with active PFC, which can alternatively operate at 24-Vdc input; a USB 2.0 interface for communication between the power supply and the backup battery via a power-management program; overvoltage and overcurrent protection on all outputs; low ripple and noise; and 0 to 70ºC operating temperature with no derating required below 40ºC.
