S7-300 Power Supply


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.

Features and Benefits


  • The system and load current supplies are screwed directly onto the S7-300 standard mounting rail and can be mounted directly to the left of the CPU

  • Diagnostic LED for indicating “Output voltage 24 V dc O.K."

  • ON/OFF switches for possible swapping of modules

  • Strain-relief assembly for input voltage connection cable

  • Short-term power failure backup

  • Output voltage 24 V DC, stabilized, short circuit-proof, open circuit-proof

  • Parallel connection of two power supplies for enhanced performance

Product Application Information


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

Why use a DIN Rail power supply?


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.

Points to consider when buying a DIN Rail power supply


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.

Protection types – It is important to choose a power supply that is protected against either short circuit, overload, over temperature or over voltage. Some power supplies also offer a hiccup mode which will allow the PSU to resume operation once the fault is cleared.

Fixed or adjustable output voltage or current – In test systems it is often convenient to have adjustable DC voltage however in other applications a fixed DC supply may be essential.

Cabling and wiring – The input/output lines to and from the power supply should be as short as possible with a large cross sectional area to help minimise noise and heat.

Efficiency – Choose a power supply that has a high efficiency to minimise the amount of power dissipation, especially if the system relies on convection cooling.

Input voltage range – If the DIN Rail power supply you are buying is to be used in Europe and North America as well as the UK then a universal AC input range of 80 V ac to 264 V ac is required.

Notes


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

Siemens DIN Rail Power Supply Unit, 24V DC Output Voltage, 5A Output Current - SIMATIC S7-300 Series - 6ES7307-1EA01-0AA0


Use this power supply unit (PSU) from Siemens to efficiently power your PLC (programmable logic controller). The device is protected against short circuits thanks to its self-restart capabilities and it will automatically shut down in the event of a power failure. Screw terminals ensure a simple and secure connection. Thanks to its wide operating temperature range of 0°C to +60°C, it's suitable for use in both hot and cold industrial environments. You'll commonly find a PSU like this one used for industrial engineering applications.

• Space-saving dimensions of 125 (height) x 60 (width) x 120mm (depth)
• Light weight of just 600g to minimise strain on your equipment
• Green LED clearly indicates operating status for ease of use
• IP20 (ingress protection) rating means it's touch-proof and protected against objects larger than 12mm in size
• Accommodates parallel connection of two PSUs to enhance performance and efficiency

How do I mount this PSU?


This PSU is designed to be clipped quickly and easily onto a standard DIN rail.
