Selecting a Power Supply Unit
4.1
Supplying Electromechanical Components
Phoenix Contact generally recommends using enclosed devices for industrial applications
because they ensure particularly high protection of persons and systems.
A regulated output voltage is not generally required for supplying electromechanical
components such as valves, relays or electromagnetic switches.
It is therefore sufficient to use an unregulated power supply unit for this.
If, additionally, reduced space requirement and high efficiency are demanded, Phoenix
Contact recommends using primary-switched mode power supply units.
4.2
Supplying Electronic Modules and Systems
Open frame devices are often used for supplying devices inside an existing housing. 19"
slide-in modules are most common for this.
For safety reasons the use of enclosed devices is recommended in control cabinets.
The use of regulated power supply units providing a stable 24 V DC output voltage
independent of input voltage fluctuations and the connected load has proved to be effective
for supplying electronic modules and systems.
In recent years, the technical development of electronic components has lead to primary-
swiched mode devices being used more and more instead of linearly regulated devices.
The major reasons for using primary-switched mode devices are high efficiency and the
associated low heat dissipation, low weight and compact design.
Phoenix Contact recommends primary-switched mode devices for universal use.
Phoenix Contact offers regulated, primary-switched mode power supply units with output
currents of 1 a to 40 A covering the complete voltage range of 5, 10, 12, 15, 24 and
48 V DC (QUINT POWER, MINI POWER and STEP POWER devices).
For supplying highly sensitive analog technology, linearly regulated devices still maintain
their position. Compared to earlier primary-switched mode controllers, linearly regulated
power supply units generate a smoother output voltage, which is almost free from residual
ripple and switching peaks.
