TECHN I CAL SP ECI FI CATI ON S – D C- D C CONVERT ER
CPL DC-DC Converter
The CPL DC to DC converter is specifically
designed to convert a wide range 48V input
voltage to a regulated 48V output voltage.
The high-density, front-to-back airflow power
entry module (PEM) is designed for minimal
space utilization and is highly expandable for
future growth.
The DC-DC converter is available with many
features including PoE isolation and dual-
redundant I 2 C communications bus for use
with a customer ’s controller. This flexible and
sophisticated feature set makes this DC PEM
an excellent choice for power in a variety of
application spaces requiring modular DC-to-
DC bulk intermediate voltages.
