HONG KONG [17 November, 2016] — Artesyn Embedded Technologies announced a new front-end bulk power supply that provides up to 495 watts in a form factor that is significantly shorter than that of similarly rated earlier-generation power supplies – conserving highly valuable system space. The DS495SPE extends Artesyn’s DS family of power supplies to now provide a consistent and scalable form/fit/function from 495 W up to 2 kW total output power, designed for deployment in networking, storage and server applications.
Artesyn has implemented advanced power switching technology and high-density component packaging techniques while providing Platinum level efficiency, peaking at up to 94 percent.
The DS495SPE 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. With a continuous output of 495 W and a wide input voltage of 90 to 264 Vac, the DS495SPE is housed in 1U high rack-mounting enclosure measuring just 3.4 x 7.7 inches (86.3 x 196.5 mm).
This power supply is fully digital and compatible with Artesyn’s universal PMBus graphical user interface, enabling control via an integral I2C interface using the industry-standard PMBus communications protocol.
The main DC output of the DS495SPE can deliver up to 41.25 A with active current sharing to maximize cost-effectiveness by eliminating the need for additional components when paralleling multiple power supplies for high current applications. This power supply is hot-pluggable and features active power factor correction. The DS495SPE has RoHS certification with Class A + 6 dB margin conducted/radiated EMI, can be delivered with standard (forward) or reverse airflow configuration and comes with Artesyn’s two-year warranty.
