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 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)
Benefits
Safe and reliable, single-phase output in the power range up to 100 W Smart system function monitoring for fault prevention for high system availability Powerful reserve capacity for lower power ranges Transient surge protection, short-circuit proof, no-load proof Tool-free installation, suited for vertical or horizontal mounting
