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.
Highly efficient, primary-switched system power supply with wide-range input of 100 to 240 VAC/ 110 to 250 VDC
Single-phase output of 24 VDC/ 2.5 A, with dynamic and static boost of 5 A
Parallel use with RNF22 for redundant system power supply
Particularly suitable for decentralized applications or control cabinets without 24 VDC power supply
For ambient temperatures –25 to 70 °C (–13 to 158 °F)
Benefits
Safe and reliable single-phase output in the power range up to 100 W
High system availability thanks to intelligent, preventive function monitoring that reports critical operating conditions before faults occur
Powerful reserve capacity even in the lower power range
Protection against transient voltage spikes, short-circuit-proof and safe for no-load operation
High efficiency and long service life with low levels of power dissipation and heat generation
Tool-free installation in any mounting position (horizontal or vertical)
Space-saving installation in the control cabinet thanks to slim, flat construction
Setting up and monitoring equipment at an ammonia plant presents significant challenges. Engie Energía uses advanced technological solutions, like remote communication devices in hazardous areas.
