Function: K24-STR-24..30VDC-10A

The slim-line power pack provides a direct voltage in an even larger adjustable output voltage range of 23 ... 30 V DC, while optimizing the space available in the control cabinet.

The current limit can be adjusted via an internal potentiometer. In addition to an LED showing the operational status (power), a red LED (overload) signals overloads on the output side.

The connecting leads on the input side are safely covered with the plastic cover after installation. The device features a convenient DIN rail fastening.
