Siemens SITOP PSU300S Switched Mode DIN Rail Power Supply 24V DC, 40A Output, 960W Power, 550V AC Input PSU300S

Siemens PSU300S DIN Rail Power Supply is a switched mode device designed for industrial power distribution systems. It accepts a 3-phase AC input voltage ranging from 340 to 550V and converts it to a stable 24V DC output at 40A, delivering 960W of power.

The unit is compact with dimensions of 150mm width, 150mm depth, and 145mm height, making it ideal for streamlined DIN rail mounting in control panels and automation setups.

It boasts high efficiency at 91.5%, which reduces heat dissipation and improves energy utilization. The IP20 rating allows use in controlled indoor environments, while the ATEX hazardous area certification ensures safe operation near flammable gases and combustible dust.

Operating temperature range extends from -25°C minimum to 70°C maximum, enabling reliability in various harsh industrial settings.

The output voltage can be finely adjusted from 24V to 28V to compensate for voltage drops over long cable runs. The power supply withstands brief functional overloads at 1.5 times its rated current, providing solid protection for connected equipment.

It integrates with buffer, DC UPS, redundancy, and selectivity modules to enhance 24V system availability and resilience. Compliance with multiple standards like CE, UL 508, CSA C22.2 No. 60950-1, and EN 61000 series certifies its suitability for global industrial installations.
