SIEMENS SITOP POWER 5
SITOP Modular Power Supplies
SITOP modular single-phase and two-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 power supply systems or directly between the phase conductors of three-phase (two-phase) power supply systems and ensures high reliability even in the event of large voltage fluctuations. The Power Boost function delivers up to three times the rated current for short durations. In the event of overload, a choice of constant current with automatic restart or latching shutdown is available.
High efficiency reduces power consumption and heat buildup in the control cabinet, and the compact metal housing also saves space. To increase 24 V availability, SITOP lite power supplies can be combined with UPS dc, redundancy and selectivity modules. Regardless of industry or requirements, Siemens offers reliable and efficient power supplies for every plant.

Why should I use a DIN rail power supply?
The flexibility of DIN rail mounting systems allows installation to be completed in less time, as all devices are installed by snapping them onto the metal rails. Power supplies can be easily arranged on DIN rails in enclosed wall boxes or in areas where space is limited. Similar devices can be mounted side by side, which reduces the amount of cables required. Most power supplies are convection cooled, so cooling fans are not required.
DIN rail ac to dc power supplies are used in many automation, instrumentation and industrial applications. They are used to power a wide variety of dc driven devices such as sensors, motors, actuators, solenoids, relays, etc.
Things to consider when purchasing a DIN-rail power supply
DIN rail size: There are three common types of DIN rail. U-section, G-section and C-section. Most are 7.5 mm or 15 mm deep. It is advisable to check that the power supply is compatible with the DIN rail.
Types of protection: It is important to choose a power supply with short circuit, overload, over temperature or over voltage protection. Some power supplies also offer a hiccup mode, which will allow the power supply to resume operation after the fault disappears.
Fixed or adjustable output current or voltage: in test systems it is often practical to have an adjustable dc voltage, while in other applications it may be more practical to have a fixed dc supply.
Wiring: power supply input/output lines should be as short as possible and have a wide cross-section to minimize noise and heat.
Efficiency: select a power supply with high efficiency to reduce power dissipation, especially if the system employs a convection cooling system.
Input voltage range: If the DIN rail power supply you are purchasing is to be used in Europe and North America, as well as the UK, it needs to have a universal ac input range of 80 V ac to 264 V ac.
Standards: If the power supply is to be used in the USA to control electric motors, it must comply with the UL508 standard for safety in industrial control equipment.
