DS495SPE Series


495 W Front End AC-DC Power Supplies

The DS495SPE 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 shorter than similarly rated earlier-generation power supplies, freeing up valuable system space. DS495SPE  is fully digital and compatible with Advanced Energy's universal PMBus® graphical user interface, allowing control via an integral I2C interface using the industry-standard 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 A for power management circuitry. The main DC output of the DS495SPE can deliver up to 41.25 A.
