Field of application
The RNB22 is a compact, high-efficiency primary switch mode power supply for DIN rail interface systems. It delivers a reliable, single-phase, 24 VDC / 2.5 A output and runs on a wide-range input from 100 to 240 VAC / 110 to 250 VDC, with a dynamic and static boost of 5 A and 3.125 A respectively.
When run in parallel with the RNF22 error message module, the RNB22 provides redundancy, increased capacity, as well as function monitoring to report critical operating states before errors occur.
High-efficiency 24 VDC / 2.5 A power supply with low power dissipation
