The Omron S8fs-G15024CD is a 150 W switch-mode power supply that bolts onto a DIN rail and delivers 24 V DC at 6.5 A from a single-phase input. That's the kind of brick you drop into a control cabinet to run a PLC rack, a handful of DC coils, or a small HMI — nothing exotic, just steady 24 V bus power with screw terminals and a green LED to tell you it's alive.
Real-world numbers, not just catalogue specs
Rated efficiency hits 90% at 230 VAC, which keeps the heat out of a crowded panel. Hold-up time is listed at 10 msec minimum and 55 msec typical — that 55 msec window is enough to ride through a brief line dip without dropping the DC bus on a controller. Output noise is capped at 110 mV, clean enough for most digital loads but worth a check if you're feeding sensitive analog cards without a secondary filter. The 28 A inrush current on startup is a single-phase number; size your upstream breaker and wire accordingly — the unit accepts up to 12 AWG at the screw terminals. MTBF is 135,000 hours, which is about 15 years continuous run at 40 °C ambient, so this isn't a part you plan to swap every five years.
Standards and compliance — what the approvals actually mean
The S8fs-G15024CD carries UL 508 listing for industrial control equipment, UL 60950-1 recognition for ITE (information technology equipment), cUL and cUR for Canada, and VDE for Europe. It also meets SEMI F47-0706 for voltage sag immunity at 200 VAC input — that's the semiconductor fab standard, so it's built to stay online through the brownouts common in factory power distribution.
The housing is aluminum and stainless steel — no plastic that cracks when you torque the terminals. Dimensions are 44.2 mm wide, 97 mm tall, 197 mm deep, so it takes about 1.75 inches of DIN space. Screw terminals accept 12 AWG max; strip length isn't given, but 8 mm is a safe starting point for this terminal class.
Protection and diagnostics at a glance
Built-in overload protection, overvoltage protection, and automatic reset — it folds back on overload and comes back when the fault clears, no manual reset needed. Green LED for output status. Series operation is supported, so you can wire two units in series for 48 V if the application calls for it.
