The Siemens LOGO!Power 24 V / 1.3 A Power Supply (6EP3331-6SB00-0AY0) is a stabilized industrial power supply designed for reliable and continuous power delivery in automation and control systems. It belongs to the Siemens LOGO!Power family and is optimized for supplying LOGO! PLCs, expansion modules, sensors, and auxiliary control devices.
The power supply supports a wide-range input and can be operated on single-phase AC (100–240 V AC) or DC (110–300 V DC) networks. It delivers a regulated and galvanically isolated 24 V DC output with a rated current of 1.3 A, ensuring stable voltage even under fluctuating mains conditions.
Integrated protection functions include short-circuit protection, overload capability, and overvoltage protection. The device features a soft-start characteristic with no output voltage overshoot, protecting connected automation components during startup. A green LED indicator provides clear visual confirmation of correct output voltage.
With efficiency up to 86% and a compact enclosure width of only 36 mm, the LOGO!Power 1.3 A unit is ideal for space-constrained control panels. It supports parallel operation of up to two units to increase available output power and can be mounted on a DIN rail or directly on a wall.
