Configured for three-phase AC power conversion in control cabinet distribution networks, the Omron S8VK-WA48024 (S8VK-W Power Supply) provides direct physical/electrical execution. It transforms a three-phase 200 to 240 VAC input into a regulated 24 VDC bus voltage, supplying up to 20 A continuous output current and a 30 A peak boost capacity to power field devices and PLC I/O racks.

Model Number Code Identification

• S8VK-W: Three-phase switch-mode power supply product series designation
• A: Rated line input voltage specification covering 200 to 240 VAC three-phase
• 480: Maximum continuous output capacity rating of 480 W
• 24: Regulated nominal output voltage rating of 24 VDC

Physical & Performance Parameters

Industrial Fieldbus and Deterministic Logic Backplane Powering

Delivering a ripple-free 24 VDC output bus, the unit maintains clean DC power stability across fieldbus couplers and distributed control racks. Stable power conversion prevents logic resetting and bus voltage drops during peak load demand, preserving backplane bus communication velocity Licences in high-density automation control cabinets. This power integrity ensures uninterruptible frame transmission across Profinet / EtherNet/IP deterministic networks during high I/O density scaling.

Standard Delivery Items

• 1 x Push-In Plus terminal block connector set
• 1 x Compact installation manual sheet

Cabinet Mounting and Wiring Recommendations

Rail Installation and Thermal Clearances

• Snap the module vertically onto standard 35 mm DIN rail, verifying that upper and lower mounting clips are latched.
• Maintain a minimum clearance of 25 mm horizontally and 75 mm vertically to allow proper heat convection through the ventilated enclosure.

Terminal Connections and Grounding

• Strip solid conductors or ferruled stranded wires and insert directly into the Push-In Plus terminal block receptacles.
• Connect the protective earth (PE) screw terminal to the main panel grounding bar using a low-impedance copper grounding conductor.

Engineering Technical FAQs

• What primary input AC voltage range triggers nominal operation for this module?

  The power supply unit operates within a three-phase rated input range of 200 to 240 VAC.

• How does the Push-In Plus terminal design affect conductor installation?

  Push-In Plus terminals allow tool-free insertion of ferrules or solid wires, reducing field wiring installation time.

• What maximum boost current can the output section supply during high peak loads?

  The unit provides up to 30 A maximum boost current to support high-inrush loads such as DC motors or capacitive banks.

• Can this power supply operate without active fan cooling inside an enclosure?

  Yes, the metal housing utilizes natural convection cooling and requires no internal or external cooling fans.

• What ingress protection level does the covered enclosure frame provide?

  The housing meets IP20 protection standards under EN/IEC 60529 for finger-safe panel enclosure installations.

• What maximum continuous DC power output capacity is available from the terminals?

  The device supplies a continuous 24 VDC output at 20 A, delivering up to 480 W total continuous output power.

• Is hot-swapping input or output connections permitted while line power is active?

  No, power source leads must be isolated prior to removing terminal blocks to prevent terminal arcing and equipment damage.

• What thermal operating envelope is supported during continuous full-load execution?

  The power supply unit maintains rated output performance across an operating temperature range of -40 to 70 deg C.
