RNB22 system power supply unit

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)

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
