Din Rail power supply manufacturer
PULS UK has introduced data
logging to its single-phase QS40 and
three-phase QT40 1Kw units. The
move will enable the company to
establish life expectancy figures based
on actual in service conditions.

PULS uses semi conductor
technology to collect data relating to
operating temperature, input
voltages and other vital information
which can later be downloaded to
calculate the life expectancy of the
product. The company is also
developing a version that can be
downloaded externally allowing
customers to monitor the condition
of the power supply and schedule its
replacement during normal
maintenance programmes.
