Siemens LOGO!POWER Switched Mode DIN Rail Power Supply, 100 → 240V ac, 24V dc dc Output, 600mA Output, 14W

Siemens LOGO!Power DIN Rail Mount Power Supplies

The miniature LOGO!Power power supply units in the same design as the LOGO!8 modules offer great performance in the smallest of spaces. The high degree of efficiency across the entire load range and the low power loss in no-load operation ensure efficient operation. The wide-range input for single-phase supply systems and for DC power networks as well as the power reserve when switching on capacitive loads satisfy the requirements of numerous applications. The large temperature range and extensive certifications make them suitable for universal use. The reliable power supplies with their flat, stepped-profile enclosure can be integrated extremely flexibly, for example in distribution boards. Regardless of the industry or requirements, Siemens offers reliable and efficient power supplies for every plant.

The reliable power supplies with their flat, stepped housings can be flexibly integrated in numerous applications, for example in distribution boards.

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.


• Standards – If the power supply is to be used in the USA for controlling electric motors then it will need to comply with Standard UL508, the safety standard for industrial control equipment.
