Power supply 12V / 15W for DIN rail mount

Compact DIN Rail Power Supply

15 Watt power supply for DIN rail mount per DIN EN 60715

Properties:

General information:

  • Compact housing cross-section (similar to a circuit breaker)
    • allows use of the power supply in building automation control cabinets
  • Flexible in application:
    • Generous 100...240V input range
    • CE Marking and UL Listed
  • High efficiency: typ. 85%
  • Large operating temperature rnage: -20..+60 degrees Celsius
  • Compact DIN rail housing: 25 x 93 x 56 mm
  • Standards-conformal for both office and industrial environments:
    • Increased noise immunity for industrial areas
    • Stricter noise emission for residential and commercial areas

Background information

W&T Web-IOs are often used in larger quantities at a centralized location. In such situations a common power supply for the devices makes the application much more transparent than would be the case if the devices were powered individually.

If there is not already a 12V power supply in the installation, this problem can be solved elegantly and cost-effectively with the 15W DIN rail power supply #11087, which can be used to power multiple 12V devices.

Of course the power supply can also be used where in addition to the 12V supply for the Web-IO assembly group power is also required for the rest of the installation. In this case you simply need to ensure that the total current draw does not exceed the rating of the DIN rail unit.
