The DS1600SPE is an ultra-high density power supply providing 35 W per cubic inch. This 1600-W power supply is housed in 1U high rack-mounting enclosures measuring just 3.4 x 7.7 inches (86.3 x 196.5 mm). The latest power-switching technology and high-density component packaging techniques enable a significantly shorter form factor than similarly-rated earlier-generation power supplies, freeing up valuable system space. The DS1600SPE is fully digital and compatible with our universal PMBus®, allowing control via an integral I2C interface using the PMBus communications protocol. Each power supply generates a main payload output of 12 VDC for feeding downstream DC-DC converters in systems using distributed power architectures, together with a 12 VDC standby output rated at 3.5 A for power management circuitry
