The RNB22 is a highly efficient, compact system power supply and a mainstream switch-mode power supply for DIN rail mounting. It provides a reliable single-phase 24 VDC / 2.5 A voltage output over a wide input range of 100...240 VAC / 110...250 VDC, with dynamic and static boost currents of 5 A and 3.125 A respectively.
When used together with the RNF22 error message module, the RNB22 provides redundant power, increases capacity and performs function monitoring, reporting critical operating states before errors occur.
Advantages
Safe and reliable single-phase output with power up to 100 W
Equipped with intelligent system function monitoring to prevent failures and increase system availability
Powerful energy storage capacity in the lower power range
Transient inrush current protection, short-circuit protection, no-load protection
Installation without additional tools, can be installed vertically or horizontally
Field of application
Highly efficient 24 VDC / 2.5 A power supply with low power consumption
Works in parallel with the RNF22 for redundant power supply
Can be used in distributed control applications or remote control cabinets
Compact housing that makes efficient use of the space inside the control cabinet
Virtually no heat dissipation, no lateral installation spacing required
Ambient temperature range: –25...70 °C (–13...158 °F)
