RS PRO Switched Mode DIN Rail Power Supply, 85 → 264 V ac / 120 → 370V dc ac, dc Input, 12V dc dc Output,

Need to convert currents from AC to DC in order to charge a DC appliance? This compact power supply is adjustable between 10.8 and 13.8 V DC to suit the device you're operating. You can easily mount it on a DIN (Deutsches Institut für Normung)rail and it's highly immune to noise, which means it works well in loud settings.
For energy efficiency, the unit uses minimal power when in standby mode. Thanks to its light weight, it's easy to shift between sites. Its minimal ripple and noise effect of 120 mV means it won't damage any sensitive kit stored nearby.
This device is highly reliable with a mean time between failures (MTBF) of over 300,000 hours. It also comes with short-circuit, overcurrent and overvoltage protection to keep you safe.
