2. Introduction
The DC power supply P 6227 is equipped with a high-quality code potentiometer to achieve a high
stability of the DC voltage and the DC output. It is a constant voltage power supply, which provides
a freely adjustable output voltage between 0V and 60V DC.
The output current adapts to the output voltage and can be up to 6A at 25V DC or only 2.5A at 60V
DC. If the voltage is regulated via 25V DC, the maximum current drops continuously up to 60V DC,
so regulation follows the output voltage. The coarse and fine adjustment can be switched as
required by pressing a button. The voltage gradation is precise with 1 V or 10 mV and the current
setting in 100 mA or 1 mA steps.
The model also has two 5V / 1A USB interfaces, which are used e.g. can be used to power single-
board computers and development boards.
