Function: K26-STR-24VDC-2A

The particularly narrow power supply provides direct current with an output voltage of 24 V DC ± 3 % and provides optimum utilization of space in the control cabinet.

The wide range input enables operation with an input voltage of 94 to 265 V AC with an improved efficiency of 89 %.

The power supply is continuous open-circuit and continuous short-circuit proof. An LED indicates operation (power).

The device features a convenient mounting rail attachment.
