Siemens SITOP PSU300S Switch Mode DIN Rail Power Supply 340 → 550V ac Input, 24V dc Output, 20A 480W

SITOP Smart Power Supply Units

The 1 and 3 phase SITOP smart is the universal and powerful standard power supply for machinery and plant engineering. Despite their compact design, they offer an excellent overload response. Thanks to a power boost of 150%, loads with high power consumption can be connected without any problems. The permanent overload capability of 120% offers power reserves in-case of expansions. The high degree of efficiency results in low energy consumption and minimal heat generation inside the control cabinet.
To increase the 24 V availability, the SITOP smart power supply can be combined with buffer, DC UPS, redundancy and selectivity modules.

Features and Benefits

• Compact design
• Extra power with 1.5 times the rated current for brief functional overload
• Permanent overload capability with 1.2 times the rated current up to 45°C (24 V versions)
• High degree of efficiency up to 91.5%
• Adjustable output voltage for compensating voltage drops
• Signalling contact for easy integration in the plant monitoring system
• Wide temperature range from -25°C or -10°C to 70°C

Product Application Information

SITOP power supplies can be combined with buffer modules, uninterrupted power supplies, redundancy modules 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.

Siemens DIN Rail Power Supply, Switch Mode, 340 to 550V AC Input - SITOP PSU300S Series - 6EP1436-2BA10

Looking for an efficient and compact power supply for machinery and plant engineering? This 3-phase switch mode unit from Siemens' SITOP range delivers excellent overload response from small dimensions of 90 (W) x 150 (D) x 145mm (H). It clips easily onto a DIN rail to help you build a neat and organised system, while up to 91.5% efficiency means it generates minimal heat inside the cabinet. For reliability, the device can handle 1.5 times the rated current during a brief functional overload.

• Operating temperature range of 0°C to +70°C for use in harsh industrial environments
• Safe to use in the presence of flammable gases or combustible dust
• Ripple and noise of 150 mV Pk-Pk for low energy wastage
• Adjustable output voltage between 24 and 28V lets you compensate for voltage drops
• Signalling contact offers easy integration into a plant monitoring system

How does a switch mode power supply work?

A switch mode power supply uses switching devices to continually turn on and off at high frequency, which is more efficient than a linear power supply.
