Siemens SITOP PSU200M Switched Mode DIN Rail Power Supply, 85 → 264V ac ac Input, 24V dc dc Output, 5A Output,

Use this switch-mode power supply from Siemens to convert electric power from AC to DC. It has an input voltage range between 85 and 264VAC, making it practical in industries with high voltage fluctuation. The unit's power-boost function enables you to increase the power by up to three times the nominal current, which is ideal for short periods when you're running a lot of equipment at the same time. It emits noise of less than 50mV (millivolts), so it won't interfere with other machinery or devices.

• Compact dimensions of 125 (H) x 121 (W) x 121mm (D) make it practical for use in tight spaces
• 88% efficiency rating to minimise electrical dissipation
• Straightforward and quick to install using the DIN rail mounting system

No, this power supply doesn't generate a lot of heat as the unit uses very little energy.

The unit is suitable for use in automation, instrumentation and industrial applications. This is because it takes mains electrical power and converts it for use with machinery that has 24V DC circuitry.
