Murrelektronik MCS20 Series Technical Notes

The Murrelektronik MCS20 series is a line of DIN-rail-mounted switched-mode power supplies (SMPS) engineered for continuous-duty industrial environments. Deployed across chemical processing plants, oil refineries, nuclear auxiliary systems, and heavy manufacturing facilities, the MCS20 range converts single-phase AC input (100–240 V AC or fixed 230 V AC) to regulated 24 V DC output at current ratings from 1.3 A to 20 A. Its compact form factor, high efficiency (up to 93%), and wide operating temperature range (−25 °C to +70 °C) make it a standard specification item in European and Asian process automation projects. The series complies with EN 61000-6-2 (industrial EMC immunity), EN 61000-6-4 (industrial EMC emission), and carries CE, UL, and cUL marks. Parallel operation for redundancy and load sharing is supported across the range, a critical requirement in safety-instrumented systems (SIS) and distributed control system (DCS) power architectures.
