The SIMATIC PS307 single-phase load power supply (system and load power supply) with automatic input voltage range selection is optimally adapted to the SIMATIC S7-300 controller in its design and functionality. The power connector, which is included in the scope of delivery of the system and load power supply, enables quick supply of the CPU. The 24 V supply of other S7-300 system components, input/output circuits of the I/O modules and, if applicable, sensors and actuators is also possible. Extensive certifications such as UL, ATEX and GL enable universal use. Regardless of the industry or requirements, Siemens offers reliable and efficient power supplies for every plant.

Comprehensive certifications, such as UL, ATEX and GL enable universal use in various industries.

The flexibility of DIN Rail mounting systems enables quicker installation time as all devices are able to simply snap onto the metal rails. Power supplies can be easily organised on DIN Rails within enclosed wall boxes or in areas where there is limited space. Similar devices can be mounted next to each other reducing the amount of cabling required. Most power supplies are convection cooled so no cooling fans are needed.
DIN Rail AC to DC power supplies are widely used in many automation, instrumentation and industrial applications. They are used to power a wide variety of DC operated devices including sensors, motors, actuators, solenoids, relays and many more.

DIN Rail size – There are three common types of DIN Rails. Top Hat, G section and C section. Most have a depth of 7.5 mm or 15 mm. It is wise to check that your power supply is compatible with your DIN Rail.

Each CPU requires a Micro Memory Card (MMC). Programming may be carried out using the Step 7 Lite software (stock no. 539-1755).

Ensure steady voltage supply to your industrial equipment using this DIN rail power supply from Siemens. It works by adjusting the input voltage supply to a regulated level for the output voltage. For easy setup, the unit is designed for use with controllers from the SIMATIC S7-300 range. A load regulation of 0.2% means it'll maintain a stable output voltage even if there are fluctuations in the input voltage supply. Thanks to compact dimensions of 120 (H) x 40 (W) x 125mm (D), you can easily fit it onto a busy DIN rail to power sensitive electric components like your sensors and relays.

• Low ripple and noise of 50 mV PK-PK for reduced electrical disturbance
• Power rating of 48W to withstand heavy-duty systems
• LED indicator for easy status configuration
• Short-circuit protection to prevent electric hazards
• Screw terminals for a stable electric connection

This power supply can adjust input voltages between 120 and 230V AC to a stable output voltage of 24V DC. It comes with automatic input voltage range selection so you don't have to set it manually.
