Siemens SITOP PSU8200 Switch Mode DIN Rail Power Supply, 320 → 575V ac ac Input, 24V dc dc Output, 40A Output,

The SITOP modular single-phase and 2-phase power supplies are technology power supplies for demanding solutions and provide maximum functionality for use in complex plants and machines. The ultra-wide-range input enables connection to single-phase supply systems or directly between the phase conductors of 3-phase supply systems (2-phase) and ensures high reliability even in the case of large voltage fluctuations. The Power Boost function supplies up to three times the nominal current over short durations. If overload occurs, there is a choice between constant current with automatic restart or latching disconnection.

The high degree of efficiency minimizes energy consumption and heat generation in the control cabinet, and the compact metal enclosure also saves space. To further increase 24 V availability, the power supplies can be combined with buffer, DC UPS, redundancy and selectivity modules. Regardless of the industry or requirements, Siemens offers reliable and efficient power supplies for every plant.

To increase the 24 V availability, the SITOP smart power supplies can be combined with buffer, DC UPS, redundancy and selectivity modules.

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.

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.
