SIPLUS power supplies
Introduction
■
Overview
Particularly harsh industrial environments demand products with
special characteristics - products that are more rugged than
standard products.
Siemens offers the perfect answer to these requirements with
SIPLUS extreme.
SIPLUS product variants are based on the SITOP, LOGO!Power
standard power supplies and the power supplies for SIMATIC S7
and expansion modules, and feature the following characteri-
stics:
•
Extended ambient temperature range (e.g. -40 … +70 °C)
and conformal coating as protection against extreme and
difficult conditions and contact with substances
•
DIN EN 50155:
Conforms with standard for electronic equipment used on
rolling stock (EN 50155, temperature T1, category)
