Product Overview
The Omron S8VK-C12024 is the 120 W member of the S8VK-C line — the cost-effective tier of Omron's S8VK family. It delivers 24 VDC at 5 A from a single-phase 100 to 240 VAC (or 90 to 350 VDC) input, with 89% typical efficiency and a 3-year warranty. The C line suits budget-sensitive indoor panels where the G line's 5-year warranty and the S line's harsh-environment rating are not required, and where the load sits between 2.5 A and 5 A.
Choosing between the S8VK-C, S8VK-G, and S8VK-S 120 W models
All three deliver 24 VDC at 5 A from the same 100 to 240 VAC input, in the same 40 x 125 x 113 mm footprint as the C and G lines. S8VK-C12024 (this SKU) is the cost-effective pick: screw terminals, -25 to 60 °C, 3-year warranty. S8VK-G12024 is the global-harmonized general-purpose line: -40 to 70 °C, 5-year warranty, and a 120% power boost (6 A for 5 s) for starting capacitive loads. S8VK-T12024 is the three-phase 200 to 240 VAC input line for plants that already have three-phase mains at the cabinet. Pick the C12024 when the cabinet is climate-controlled and the 3-year warranty is acceptable; pick the G12024 for most new installations; pick the T12024 for three-phase mains.
Before ordering or installing
Check the derating curve before specifying: standard mounting delivers 100% output at 40 °C and derates linearly to about 75% at 60 °C. If your panel runs above 40 °C, size up to the S8VK-C24024 (10 A) to keep the load at 50% of rating. Tighten the screw terminals to 0.5 to 0.6 N·m. The S8VK-C line does not support direct parallel operation; for 1+1 redundancy, add an S8VK-R20 redundancy unit between two supplies. Series operation (stacking two for ±24 V or 48 V) is supported with an external diode on each output. The output voltage is adjustable from -10% to +15% via the V.ADJ trimmer on the front face.

FAQ for S8VK-C12024
How do I choose between S8VK-C12024, S8VK-G12024, and S8VK-T12024?
All three deliver 24 VDC at 5 A in the same 40 x 125 x 113 mm footprint. S8VK-C12024 (this SKU) is single-phase 100 to 240 VAC, 3-year warranty — the cost-effective pick. S8VK-G12024 is also single-phase but adds -40 to 70 °C range, 5-year warranty, 120% power boost (6 A for 5 s). S8VK-T12024 is three-phase 200 to 240 VAC — for three-phase cabinets. Pick C12024 for budget single-phase, G12024 for most new installs, T12024 for three-phase mains.
Can I parallel two S8VK-C12024 units for redundancy?
Not directly. The S8VK-C line does not support internal current sharing, so paralleling two C12024 supplies output-to-output will fight each other and may fault the overvoltage protection. For 1+1 redundancy, add an S8VK-R20 redundancy unit between the two supplies and the load — it isolates the outputs, decouples the load, and gives a redundancy-OK signal. Series operation (stacking for ±24 V or 48 V) is supported with an external diode on each output.
What fuse or circuit breaker do I need on the AC input?
The internal fuse is 250 VAC 8.0 A HBC (high breaking capacity), not user-replaceable. For external protection, fit a 10 A or 13 A slow-blow MCB on the AC feed — fast-blow breakers will nuisance-trip on the 16 A peak inrush at 115 VAC or 32 A peak at 230 VAC (cold start at 25 °C). Allow at least 1.5 mm² (AWG 16) wire for the input and 4 mm² (AWG 12) for the 5 A output.
What happens if the panel temperature runs above 50 °C?
Above 40 °C the S8VK-C12024 derates linearly: about 90% of rated load at 50 °C and about 75% at 60 °C (standard mounting). For a panel that runs above 50 °C continuously, step up to the S8VK-C24024 (10 A) to keep the load at 50% of rating, or to the S8VK-G12024 which runs to 70 °C without derating. Side-by-side mounting and face-up mounting both derate further; check the datasheet derating curve for your exact layout before specifying.
