DS Short Series AC-DC Power Supplies (Part 1)

DS Short Series AC-DC Power Supplies (Part 2)

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 significantly shorter than that of similarly rated earlier-generation power supplies — freeing up valuable system space — and is achieved by use of the latest power switching technology and high density component packaging techniques.
DS495SPE power supply is fully digital and compatible with Artesyn Embedded Technologies' 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. Active current sharing helps maximize cost-effectiveness by eliminating the need for additional components when paralleling multiple power supplies for very high current applications.
This power supply is certified for Platinum Level efficiency, peaking at 94% of efficient power conversion.
