Power modules offer ultra-wide input voltage for industrial applications
Ericsson has introduced two new series of DC/DC converter modules that are primarily aimed at industrial and railway transportation applications, as well as information and communications technology (ICT) applications that are operated with remote power supplies and/or multiple battery voltages. Suited to use in distributed power architectures and industrial control systems, these robust modules target typically 12V, 24V or 48V power supply line applications that require a board power supply to operate across a large range of input voltages, and without disrupting output characteristics when the input line is experiencing very high fluctuation.
The PKE3000PI operates over an input voltage range from 9V to 36V and the PKE5000PI operates from 18V to 75V. Each series offers four output voltages, delivering 3.3V/4.5A; 5V/3A; 12V/1.25A and 15V/1A. Offering a high efficiency of typically 89% at 12V out (full load), the modules offer low power dissipation and good thermal characteristics.
The modules measure 25.4 x 25.4 x 10.8mm (1.00 x 1.00 x 0.4 in), and come in encapsulated packaging, protecting the modules from dust, high humidity and highly corrosive or highly vibrational environments, which are commonly found in industrial or railway/transportation applications.
The modules meet requirements for board development purposes or remote-feed applications where voltages are delivered to the load via long cables. In this case, the board power converter is required to secure stable input voltage whatever the length of cable and wherever the board is connected.
Meeting basic insulation and safety requirements according to IEC/UL60950-1, and offering 1500V I/O isolation and an MTBF (Mean-Time-Before-Failure) of one million hours, other features of the PKE3000PI and PKE5000PI series include: output over-voltage protection; input under-voltage shutdown; over temperature protection; output short-circuit protection; output voltage adjust function; monotonic startup; and remote control.
