Omron S8VS-12024 24 VDC 5 A 120 W DIN-Rail Power Supply
Description
S8VS-12024: 120 W 24 V supply with active power factor
The Omron S8VS-12024 is a 120 W, 24 VDC, 5 A DIN-rail switch mode power supply. It has a power factor of 0.9 minimum, 87% typical efficiency at 200 VAC and an inverted-L overload characteristic that automatically recovers. Seven Star LLC supplies the S8VS-12024 in Oman and the GCC as an independent supplier in Muscat, and the sections below explain the code, ratings and variants.
- S8VS is the switch mode power supply series.
- 120 means 120 W.
- 24 means 24 VDC output.
- No letter means standard model without indication monitor.
- -F would give a screwless terminal block; A, B, BE and P letters add monitor and alarm functions.
At 5 A the unit powers mid-size control panels, and the monitor options give a path to condition-based maintenance when a plant wants it.

How S8VS-12024 works and how it protects the load
A power factor correction stage at the input keeps the mains current close to sinusoidal, giving 0.9 min. power factor. The isolated converter then regulates 24 V with 0.5% maximum input variation influence and 1.5% load variation.
The overload characteristic is an inverted L: when load exceeds 105% to 160% of rated current the output voltage drops, and the unit resets automatically once the overload is removed. This protects wiring and the supply while avoiding latch-off nuisance. Overvoltage protection is built in.
Where S8VS-12024 fits: model code, variants and related parts
The S8VS-12024 follows the 90 W S8VS-09024 and precedes the 180 W S8VS-18024. Monitor versions S8VS-12024A and S8VS-12024B have a display and a transistor alarm output rated 30 VDC, 50 mA max., and sourcing versions are marked P. Combine with an S8V-NF noise filter for noisy supply.
| Code letter | Meaning in the model number |
|---|---|
| None | Standard model without indication monitor |
| A | Indication monitor with maintenance forecast |
| B | Indication monitor with total run time |
| BE | Monitor with total run time, no alarm output |
| P | Alarm output sourcing (collector COM); none = sinking (emitter COM) |
| S | Conforms to UL Class 2 output (90 W models only) |
| F | Screwless terminal block; none = screw terminal block |
Related product named in the datasheet is the S8V-NF noise filter. The datasheet also states that estimates can be provided for coatings and other specifications not listed, so ask early if your site needs protection against corrosive air.
Selection and ordering checklist for S8VS-12024
Confirm these points before requesting a quotation for S8VS-12024.
- Sum the 24 V loads; keep below 5 A.
- Check power factor and mains conditions.
- Decide whether monitor, alarm and screwless options are needed.
- Check breaker against 35 A max. inrush at 200 VAC.
- Check panel temperature and derating.
- Plan backup with external diode if redundancy is required.
Installation, commissioning and maintenance of S8VS-12024
Mount on DIN rail with the clearances in the datasheet, connect AC and DC wiring, set V.ADJ if needed and verify output.
- Allow space for convection.
- Check terminal torque.
- Verify output at the farthest load.
- Record the voltage setting.
- Plan preventive replacement.
Typical S8VS-12024 applications in Oman and the GCC
A 120 W 24 V supply feeds mid-size PLC panels, drive control electronics, instruments and valve groups. In Oman and the GCC the S8VS-12024 is common in pump stations, HVAC plant and process skids.
Where plants need to monitor power supply health, the monitor versions give maintenance forecast or run time data; the standard S8VS-12024 suits panels without that need.
