The Omron S8VS-48024B-F is a DIN-rail-mount enclosed power supply delivering 480 W at 24 VDC, 20 A output from a 100 to 240 VAC input. That 20 A rail is sized for a moderate control cabinet — think a bank of 24 VDC contactors, a handful of PLC I/O slices, and a small HMI, all fed from one supply. Natural convection cooling means no fan to fail or whistle in a quiet panel; just keep the ambient below the derating curve and leave breathing space above and below the unit.
Smart display and protection — what the front panel tells you
The runtime display shows cumulative operating hours, which is the kind of data a maintenance planner uses to schedule preemptive swaps before a line-down failure. The preventive maintenance alarm output trips a remote signal when the supply hits a set hour count — no need to walk the panel with a clipboard. Overload and overvoltage protection are built in; the unit folds back or shuts down rather than letting a fault propagate downstream.
DIN rail integration and wiring constraints
The enclosed metal case handles the heat dissipation; natural convection means no fan filter to change. Note that parallel operation is not supported, so if your load pulls more than 20 A continuous, step up to the next frame size rather than trying to gang two units. Series operation is allowed for higher voltage rails, but that is a niche use — most buyers will run it standalone at 24 VDC.
