Power modules support ultra-wide input voltage ranges
Ideally suited to use in distributed power architectures and industrial control systems, these new highly robust modules target typically 12 V, 24 V or 48 V 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 high fluctuation.
The PKE3000PI operates over an input voltage range from 9 V to 36 V and the PKE5000PI operates from 18 V to 75 V. Each series offers four output voltages, delivering 3.3 V/4.5 A; 5 V/3 A; 12 V/1.25 A and 15 V/1 A. Offering a high efficiency of typically 89% at 12 V out (full load), the modules offer low power dissipation and excellent thermal characteristics.
The modules are small and compact, measuring industry-standard dimensions?25.4 x 25.4 x 10.8 mm, and come in highly robust 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.
In addition, 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.
