Siemens SITOP PSU100S Switch Mode DIN Rail Power Supply, 85 → 132V ac ac Input, 12V dc dc Output, 14A Output,

The Siemens SITOP PSU100S series single output switch-mode DIN rail power supply has an output current rating of 14A at 12VDC. It has a universal single and dual-phase input voltage ranging between 85VAC and 132VAC/170VAC and 264VAC with adjustable output voltage for compensating voltage drops. This offers outstanding overload features such as permanent overload capability of 120% offers power reserves in-case of expansions and power boost of 150%, loads with high power consumption can be connected without any failure. Adjustable output voltage ranging between 11.5VDC and 15.5VDC.
Why use a DIN Rail power supply?
The flexibility of DIN Rail mounting systems enables quicker installation time as all devices can 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 is 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 overvoltage. Some power supplies also offer a hiccup mode which will allow the PSU to resume operation once the fault is cleared.
The 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 an efficiency of over 89% 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.
