SITOP modular - Three phase

The SITOP modular 3-phase power supplies are technology power supplies for demanding solutions and provide maximum functionality for use in complex plants and machines. The input range enables connection to numerous power networks in the world 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 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. The variant with protective coating has improved resistance against extreme air pollution such as condensation, dust and ESD. To further increase 24 V availability, the SITOP modular 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.

Features and Benefits

  • Wide-range input from 340 to 550 V AC for global use

  • Compact design - no lateral clearances required

  • Extra power with 1.5 times the rated current (5 s/min) for brief functional overload

  • Permanent overload capability with 1.2 times the rated current up to 45 °C ambient temperature

  • Adjustable output voltage for compensating voltage drops

  • Signaling contact for easy integration in the plant monitoring system

  • Wide temperature range from -10 to +70 °C

  • Comprehensive certifications, such as CULus, ATEX or GL

Product Application Information

To further increase the availability, the SITOP modular power supply units can be combined with buffer, DC UPS, redundancy and selectivity modules.

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.
