E-T-A_PR_367_SMPE-T-A SMP single and three-phase switch-mode power supplies provide a single source for 24Vdc control system that includes: power circuit protection (4230-T) and control circuit protection (ESX10, ESX10-T, ESS30& ESS31-T). The DIN Rail mountable units are available in 5A, 10A, 20A and 40A current ratings and 24Vdc operating voltage. This corresponds to the power classes 120W, 240W, 480W and 960W. Devices have an efficiency factor of up to 93%, are designed for a maximum ambient temperature of 70C.
