Siemens SIMATIC Switched Mode DIN Rail Power Supply, 120 → 230V ac ac Input, 24V dc dc Output, 5A Output, 17W

When you need a consistent source of energy, reach for this switching power supply from Siemens. It accepts inputs from 85 to 264V AC and steps them down to a stabilised load of 24V DC. You can use this for sensitive battery-powered applications that need consistency. An isolated output helps prevent electrical faults from threatening your safety or damaging connected equipment. The built-in filter on the input, short-circuit breaking and protection against overvoltage and overload mean this device offers comprehensive electrical shielding.

• 88% efficiency means it wastes very little energy as heat and stays cool through natural convection
• Handles a broad operating temperature range from -30°C to +70°C, so is compatible with harsh environments
• Output voltage is adjustable from 22.8 to 28V DC, so it's easy to tailor the device to your application
• Quick to mount on a standard 35mm DIN rail thanks to a simple snap-on mechanism

This PSU has a mean time between failures of 1,598,441 hours, so you can rest assured it's built to last.
