Provides regulated 24 VDC power for PLCs, I/O, sensors, and relays in control cabinets that require stable low-ripple DC power.
Prevents control-voltage instability during load changes and supports dense 24 V automation loads.
Supplies auxiliary 24 VDC loads in machine panels where high inrush or transient overloads occur, leveraging TopBoost and PowerBoost behavior.
Handles short-term overloads without nuisance shutdowns during actuator start-up or simultaneous load switching.
Fits laboratory and test systems needing universal input acceptance, high efficiency, and compact DIN rail integration for instrumentation power distribution.
Simplifies global-mains deployment while minimizing heat and panel footprint in test racks.
