Power Supply Modules OF-PSU Unipolar Precision Open-Frame Power Supplies
On these pages you can find the unipolar version of our open-frame power supply modules. The bipolar version can be found here: Bipolar Power Supply Modules OF-PSU-B »
About OF-PSUThese linear precision power supply modules provide an output power of 45 W for output voltages up to about 600 V. They are characterized by extremely low noise voltages as well as very low output ripples of less than 1 ppm.
The output voltage can be set to a value between 0 and nominal voltage by a 25-turn potentiometer. The power supplies are equipped with an electronic current limiter and surge protection. They are cooled by an external heat sink.
