Omron S8VS-18024 24 VDC 7.5 A 180 W DIN-Rail Power Supply

S8VS-18024: 180 W 24 V supply with low ripple

The Omron S8VS-18024 is a 180 W, 24 VDC, 7.5 A DIN-rail switch mode power supply. In the standard model column it lists a low ripple noise voltage of 50 mV max., together with 88% typical efficiency at 200 VAC. Seven Star LLC supplies the S8VS-18024 in Oman and the GCC as an independent supplier in Muscat; the sections below set out the facts to settle before ordering.

• S8VS is the switch mode power supply series.
• 180 means 180 W.
• 24 means 24 VDC output.
• No letter means standard model; -F would be screwless terminals.
• A, B and P letters add monitor, run-time and alarm polarity options.

Low ripple matters for analogue instruments and sensitive I/O; this is a reason to prefer the S8VS-18024 over a model with higher ripple.

S8VS-18024 technical specifications

Values come from the Omron S8VS datasheet standard column. Monitor versions have 180 mV max. ripple.

How S8VS-18024 works and how it protects the load

The S8VS-18024 has an active input stage that keeps power factor at 0.9 min., then an isolated converter with output filtering that holds ripple at 50 mV max. at 24 V and 7.5 A.

The inverted-L overload characteristic reduces output voltage when load reaches 105% to 160% of rated current and recovers automatically. Overvoltage protection is built in. Backup (redundant) operation is possible with an external diode, while parallel operation for capacity is not.

Where S8VS-18024 fits: model code, variants and related parts

The S8VS-18024 sits between the 120 W S8VS-12024 and the 240 W S8VS-24024. Monitor versions S8VS-18024A and S8VS-18024B add display and alarm output. The S8V-NF filter can be added for difficult mains.

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-18024

Confirm these points before requesting a quotation for S8VS-18024.

• Sum the 24 V loads; keep below 7.5 A.
• Decide if low ripple is important for analogue circuits.
• Check inrush against breaker.
• Check derating at temperature.
• Choose screw or screwless version.
• Decide on monitor options.

Installation, commissioning and maintenance of S8VS-18024

Mount on DIN rail with clearances, wire input and output with suitable cable, and check output with a meter.

• Use ferrules.
• Leave space for convection.
• Fit branch protection on output.
• Check output at the load.
• Plan preventive replacement.

Typical S8VS-18024 applications in Oman and the GCC

A 180 W supply feeds instrument racks, I/O systems, analyser cabinets and valve groups. In Oman and the GCC it fits process control panels where analogue signals share the 24 V rail.

Low ripple helps loops measured over long cables, as in remote tank-gauging or flow measurement panels common in the region.

Storage, handling and spares for the Omron S8VS-18024

Keep Omron S8VS-18024 units in their original packaging until they are mounted. Store them indoors in a dry, dust-free room, away from direct sun and condensation. Panel shops in Oman and the GCC often hold stock in warehouses that get very hot in summer, so check that storage temperature stays within the limits given in the manufacturer datasheet.

• Check the label and order code on every unit against the drawing before it goes into the panel.
• Use the correct tool and tightening torque for the terminals, as given in the instructions supplied with the product.
• Keep a small number of spare units for each rating used on site, so that a failed or damaged part can be replaced without waiting for a new shipment.
• Record the order code in the panel documentation and the as-built drawings, so that maintenance teams can reorder the same part later.

When you plan spares for a project, group the Omron S8VS-18024 with the other parts of the same panel in one RFQ. This keeps delivery dates aligned and makes it easier to confirm stock for the whole bill of materials at once.
