Product Overview
The Omron S8VK-T12024 is a 120 W three-phase DIN-rail switch-mode power supply in the S8VK-T family, manufactured by Omron Corporation. Hengyixin Automation stocks this power supply in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
The supply accepts three-phase 380-480 VAC at 50/60 Hz, or two-phase 340-576 VAC, or 450-810 VDC, and delivers a regulated 24 VDC at 5 A continuous with a 120 percent power boost to 6 A for 10 s. The 87 percent efficiency figure keeps heat dissipation low for fanless operation. Operating temperature is -40 to 70 C ambient with no derating below 60 C.
The covered DIN-rail housing measures 40 mm W x 125 mm H x 140 mm D and weighs 600 g. Two sets of DC output terminals support parallel and series operation. Compliance covers UL 508, EN 61204-3, CE, and RoHS. The S8VK-T24024 is the same family at 240 W / 10 A.
Key Features
- Three-phase 380-480 VAC (or 2-phase 340-576 VAC, or 450-810 VDC) DIN-rail PSU
- 120 W output, 24 VDC at 5 A continuous, 120 percent power boost to 6 A for 10 s
- Fanless operation from -40 to 70 C, 87 percent efficiency, double DC output terminals
- 40 mm W x 125 mm H x 140 mm D, 600 g, UL 508 EN 61204-3 CE RoHS
- SKU: S8VK-T12024
- Series: S8VK-T compact three-phase input power supply
- Voltage: 24 VDC
Best-Fit Applications
- Three-phase cabinet power on a CJ2M machine cell where 120 W covers the PLC, HMI, and 16-point I/O without oversizing the PSU
- 24 VDC bus for a small EtherCAT cell with one R88D-1SN02H-ECT drive where 5 A continuous covers normal operation
- Spare replacement on a Sysmac NX102 line where the original single-phase S8VK-G12024 needs migration to three-phase for higher cabinet density
Buying Checklist
- Choose the S8VK-T12024 when the cabinet has three-phase 380-480 VAC and needs 120 W / 5 A at 24 VDC.
- Choose the S8VK-G12024 instead when the cabinet only has single-phase 100-240 VAC and the same 120 W / 5 A output.
- Choose the S8VK-T24024 instead when the cabinet needs 240 W / 10 A on the same S8VK-T family.

FAQ for S8VK-T12024
What is the difference between S8VK-T12024 and S8VK-G12024?
Both are 120 W / 5 A 24 VDC DIN-rail supplies. The T suffix is three-phase input (380-480 VAC); the G suffix is single-phase (100-240 VAC). Choose T when the cabinet has three-phase distribution, G when it has single-phase only. The three-phase input also accepts two-phase 340-576 VAC and DC input from 450 to 810 VDC, which gives cabinet designers a single SKU for both three-phase and DC-bus installations.
Does the S8VK-T12024 support parallel redundancy?
Yes. Two S8VK-T12024 supplies can be paralleled via the dual DC output terminals. For true redundancy, add an external OR-ing module. The S8VK-T series also supports series operation to build a 48 VDC bus from two supplies. For true N+1 redundancy where one supply can carry the full load if the other fails, add an external OR-ing module. Without OR-ing, two paralleled supplies share current but small voltage differences may still cause uneven loading.
What is the efficiency of the S8VK-T12024?
87 percent typical at full load. The supply runs fanless from -40 to 70 C ambient without derating below 60 C. Compliance covers UL 508, EN 61204-3, CE, and RoHS. The 87 percent efficiency keeps heat dissipation low enough that the supply runs fanless from -40 to 70 C ambient without derating below 60 C, which simplifies cabinet cooling.
Can the S8VK-T12024 be powered from DC input?
Yes. The supply accepts 450-810 VDC at the input terminals, which lets it ride on a DC bus from a larger rectifier or solar system. The DC input range excludes the 960 W S8VK-T96024, which is AC-only. Compliance covers UL 508 for industrial control equipment, EN 61204-3 for DC output performance, CE marking for the European market, and RoHS for hazardous-substance restriction.
