Power supply for fan control, 22 V, 1 A; Output voltage: 12 ... 22 V; adjustable via voltage signal 0-10 V
Features
Power supply for small loads that operate at a variable input voltage
The output voltage can be adjusted linearly by hand or via an analog voltage signal (0 … 10 V) in the range from 12 to 22 V, e.g., for automatically controlling fan speed in control cabinets.
Flat design allows installation in confined spaces.
Variable mounting options for space-saving installation, e.g., in recesses
