Outlook
In the field of electrical engineering the level of innovation - i.e., continual innovation -
increases at an enormous rate. To the same extent the life cycle of the products becomes
shorter.
The technical development of electrotechnical systems and components follows two
directions:
–
–
Expensive mechanical and electromechanical components are more and more being
replaced by electronic solutions.
Centrally structured electrical installations and systems are continuously being
supplemented or even replaced by distributed electronics.
Power supply units are taking on the central task of supplying electrical modules and
systems with the established 24 V control voltage. The use of regulated power supply units
is recommended for electronic components.
In the past, the devices were large and heavy. Together with their high heat loss this
contributed to the undesireable control cabinet heating.
The trend towards distributed electronics provide a new role for power supply units. Today,
the reliability of power supply units is not only responsible for the availability of individual
components but also for safe and reliable operation of complex systems. Thanks to
developments in the field of power electronics it is possible to introduce primary-switched
mode devices, which have four important advantages over conventional linearly regulated
power supply units:
–
–
–
–
Weight reduced by a factor of 3 to 5
Increased efficiency from approx. 50% to 90%, and consequently
Heat loss reduced by a factor of 5
Volume reduced by a factor of 1.5
The future definitely lies with regulated primary-switched mode power supply units.
Phoenix Contact has recognized this development at an early stage, and now offers the
complete performance range from 15 W to 960 W in a uniform design with its QUINT
POWER, MINI POWER, and STEP POWER primary-switched mode controllers.
