600W to 1,300W Quarter Bricks with 40- to 60-Vdc Input / 12Vdc Output

November 22, 2019 by Paul Shepard

Delta Electronics, Inc., has launched a new series of high efficiency quarter brick dc-dc converter modules for datacenter, high end server, and networking applications - Q54SH series family. It provides high power from 600W up to 1300W with input voltage range of 40- to 60-V and output voltage of 11.8V.

Careful electrical and mechanical designs bring very high efficiency (up to 97.8%) and excellent thermal performance of Q54SH series in the industry standard foot print (2.30”x1.45”x0.59”).

With PMBus interface, Q54SH series can remotely control or monitor power module’s status. Q54SH series also can achieve a fast load transient response. For application requiring higher power consumption, Q54SH series can be connected in parallel directly for higher power without external Oring-FET.

These dc-dc converters meet several international safety and reliability standards including EC/EN/UL/CSA 62368-1, 2nd edition, IEC/EN/UL/CSA 60950-1, 2nd edition+A2, and ISO 9001, TL 9000, ISO 14001, QS 9000.
