RS PRO DIN Rail Power Supply, 85 → 264 V ac / 120 → 370V dc ac, dc Input, 24V dc dc Output, 4.2A Output,

This Deutsches Institut für Normung (DIN) rail-mounting power supply will convert AC inputs to DC outputs. It will also transform higher voltage DC inputs to suit devices taking 24 V DC. It's ideal for powering equipment in applications such as household and building automation, industrial control equipment and electronic systems of all kinds.
A low ripple and noise rating of 150 millivolts (mV) ensures this unit won't interfere with any sensitive electronic devices nearby. What's more, it's tolerant of extreme temperatures ranging from -40°C to +70°C, making it suitable for use in harsh industrial environments.
This power supply meets EN 55032, EN 62368-1, IEC 62368-1, UL 62368-1 standards for safety. Its MTBF (mean time between failures) of over 300000 hours also means it should have a long life.
