DS2000SPE Series


2000 W Front End AC-DC Power Supplies

The DS2000SPE is an ultra-high density power supply providing 50 W per cubic inch. The 2000 W DS2000SPE power supply is housed in 1U high rack-mounting enclosures measuring just 3.4 x 7.7 inches (86.3 x 196.5 mm). This form factor is significantly shorter than that of similarly rated earlier-generation power supplies, freeing up valuable system space. The DS2000SPE is fully digital and compatible with Advanced Energy's universal PMBus®, allowing control via an integral I2C interface using the PMBus communications protocol. Each power supply generates a main payload output of 12.2 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.
