Provides regulated 24 VDC bus power for PLCs, relays, sensors, and industrial I/O in a cabinet fed from 3-phase mains.
Converts industrial 3-phase supply into a stable 24 V control voltage with low ripple and high current capacity.
Suitable for machine sections that need short-duration overload handling and secondary-side branch protection through TopBoost.
Prevents nuisance trips and improves selective protection for downstream loads under inrush conditions.
Supports parallel and series operation for architectures that require redundancy, voltage stacking, or extended DC distribution.
Enables flexible power architecture without redesigning the supply topology.
