Switchmode Power Supply - PR Electronics 2220

The power supply is based on secondary switchmode technology to achieve a high efficiency.
The output is adjustable from front potentiometer in the range 5…24 VDC.

General power supply for smaller measurement systems requiring fixed stabilized 24 VDC, or supply for any other sensors, transmitters or as a general variable power supply 5 to 24 VDC.
Two units may be connected in series for plus / minus or higher output voltage.
Suitable for PELV/SELV applications.
