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 V_DC / 2.5 A output and runs on a wide-range input from 100 to 240 V_AC / 110 to 250 V_DC, 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 V_DC / 2.5 A power supply with low power dissipation
Parallel mode with RNF22 for redundancy
Suited for decentralized applications or remote cabinets
Compact housing efficient use of space in control cabinets
Low heat dissipation, no lateral clearance required
Ambient temperature range: –25 to 70 °C (–13 to 158 °F)
