DS495SPE-3数据手册电源-外部/内部（板外）的ACDC转换器规格书PDF

描述 Description

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.
