Omron S8VK-G12024 24 VDC 5 A 120 W DIN-Rail Power Supply

S8VK-G12024: 120 W 24 V supply with power factor correction

The Omron S8VK-G12024 is a 120 W, 24 VDC, 5 A switch mode power supply for DIN-rail mounting. It is the first model in the S8VK-G line with a power factor above 0.9, thanks to its power factor improvement circuit, and it is a typical choice for panels with several I/O racks and instruments. Seven Star LLC supplies the S8VK-G12024 in Oman and the GCC as an independent supplier in Muscat.

• S8VK is the compact switch mode power supply series.
• G means single-phase wide-range input with DC option.
• 120 means 120 W.
• 24 means 24 VDC output.
• No suffix means standard; 400 would be coated.

The power factor of 0.94 minimum at 230 VAC means the supply loads the mains much more gently than the lower-rated models, which is useful when many supplies share a feeder.

S8VK-G12024 technical specifications

The input frequency range narrows to 47 to 63 Hz for this model, compared with 47 to 450 Hz on the 15 to 60 W models. Hold time is 42 ms at both 115 and 230 VAC.

How S8VK-G12024 delivers and protects its 24 V output

In addition to the usual rectifier, switching stage and isolated regulator, the S8VK-G12024 has a power factor improvement circuit at the input. This shapes the input current so the unit draws a nearly sinusoidal current, giving a power factor of 0.94 min. at 230 VAC and 100% load. The efficiency reaches 89% typical.

The Power Boost current of 6 A supports starting loads, and the output can be trimmed by −10% to +15%. Overload protection resets automatically and overvoltage protection trips at 130% of rated output voltage. The supply has no fan, relying on convection, so ventilation spacing matters more than at lower ratings.

Where S8VK-G12024 fits: wiring, redundancy and related parts

The S8VK-G12024 follows the 60 W S8VK-G06024 and precedes the 240 W S8VK-G24024. Where PLC racks and many instruments share one 24 V rail, it can be paralleled for redundancy, up to two units, per the datasheet. The S8V-CP protector separates output branches, and the S8V-NF filter reduces noise on difficult mains.

Related products named in the datasheet are the S8V-NF noise filter and the S8V-CP DC electronic circuit protector. For redundancy, two units can run in parallel, but the datasheet attaches safety precautions to that mode, so read them before wiring. Series operation of two units, using external diodes, can raise the output voltage for loads that need more than 24 V.

Selection and ordering checklist for S8VK-G12024

Check these points before asking for a quotation on S8VK-G12024.

• Sum the 24 V loads; keep continuous load below 5 A.
• Check power factor requirements; 0.94 min. helps with feeder loading.
• Confirm mains frequency within 47 to 63 Hz.
• Check breaker characteristic for the 32 A inrush at 230 VAC.
• Decide on redundancy with a second unit.
• Verify derating at the cabinet temperature.

Installation, commissioning and maintenance of S8VK-G12024

Mount on DIN rail with the clearance specified in the datasheet and connect input, PE and output. Confirm the green LED lights and check the output at the load.

• Keep clear space above and below for convection.
• Fit output branch protection.
• Measure voltage drop to the farthest load.
• Check terminal tightness after thermal cycling.
• Record installation date for preventive replacement planning.

Typical S8VK-G12024 applications in Oman and the GCC

This 120 W supply powers larger PLC systems, multi-slot I/O, drive control electronics and instrument groups in pump stations, utility panels and process skids. In Oman and the GCC it is a common ratings choice for control rooms and field panels.

The high power factor reduces the apparent load on UPS-fed panels, an important point where UPS capacity is limited.

S8VK-G family compared with S8VK-G12024

The S8VK-G series spans six power ratings. S8VK-G12024 is one of the 24 V models; the table lists the family from the datasheet ordering section.
