Phoenix Contact Switch-Mode DIN Rail Power Supply Unit, 2 Outputs, 100W Power Rating - UNO-PS/1AC/12DC/100W - 2902997

Provide reliable energy to your DIN-rail-mounted equipment with this power supply unit from Phoenix Contact. It works by converting AC source voltages ranging from 85 to 264V to a stable 12V DC output you can devices can use. It delivers up to 100W, so you can use it to power multiple items at the same time.

The unit can be connected either in series or in parallel, making it a versatile solution to suit your design specifications. Its robust thermoplastic housing provides impact and abrasion resistance, so it's a practical choice for use in harsh environments. For improved electrical safety, an internal 4A slow-blow fuse cuts power to the device in the event of a short circuit, while a varistor shields it from surge currents, preventing damage to connected components. This power supply is commonly used in factory automation and power distribution applications.
