Current loop power supply/ Power supply 24 Vac Stabilized power supply with 115 / 230 Vac mains input and 24 Vdc 40 mA output. Used industrially to power instruments in 4-20 mA current loop or to power from the mains instruments that require 24 Vdc stabilized voltage. The input is protected against line overvoltages by means of a varistor. The insulation between the mains and low voltage circuits is 4500 Vac. The output is self-protected against short circuits. The self-extinguishing Noryl case is the width of 2 DIN modules and is designed to fit on 35 mm mounting rail (DIN 46277).
