S8VK-S Power Supplies

World’s Smallest Class of Power Supplies

Introducing the new S8VK-S Power Supplies, for more compact control panels.

Part of the S8VK series, the new global S8VK-S Power supplies provide greater value with more space savings, greater flexibility and more resistance to extreme environments.

Greater Cost Savings In Logistics And Space Usage

Reduction In Total Panel Size

Constant innovation of our power supplies has led to an overall reduction of 36% in size of the new S8VK-S power supply. As such, great savings in terms of logistics and space usage are unlocked for users. In addition, users now have more space for other components and devices in their machines.
Technology for Greater Efficiency and Less Loss
Technology developed for the S8VK-G has been advanced even further to reduce switching loss and to reduce the loss from heat-generating components, such as transformers and diodes. This has enabled downsizing and high-density mounting of mounted components.

Reduces Dead Space And Design Time

Through Side-By-Side Mounting

With OMRON Thermal Control Technology, we achieved an engineering breakthrough in redesigning our power supply. Multiple power supplies with side-by-side mounting is now made possible, largely reducing the amount of dead space in control panels.

Users thus get to save 30% of space for future expansion of components, as well as time on calculating thermal distribution from the power supply.

Sophisticated Thermal Control Technology
Through OMRON’s unique thermal modeling, fast and accurate thermal simulation methods are established. This allow us to build an optimum component layout with precise control in heat flow. By optimizing the shape and size of the heat sink, both downsizing and side-by-side mounting of the Power Supplies was achieved.\

Stable Operations In A Wide
Range Of Environments

Stable Operations In A Wide Range Of Environments

The S8VK-S power supply is built in mind for application in many locations with different and extreme environment factors. This brings stable functionablity in extreme environments, preventing any technical delay in production line uptime, and ensuring quality delivery of equipment to end users.

Performance At High Altitudes Up To 3,000m

With A Wide Temperature Range

The S8VK-S power supply has a wide ambient operating temperature range of -40°C to 70°C, applicable for usage in tough environments from extreme cold to extreme hot.

In addition, reinforced insulation allows it to perform in environments with low atmospheric pressure – Altitudes up to 3,000m

High Resistance To Extreme Environments

With OMRON Coated PCBs

Coated PCB (OMRON Technology) provides resistance and empower performance in a wide range of extreme envirionments:
Salt Damage
Salt Damage
The coating of the power supplies is done with high evenness and coverage that prevents the occurance of short-circuits.

Stable Operations

Resistance Against Poor
Power Quality

S8VK-S is able to provide stable operation even on sites with poor power quality condition. Abnormal input voltages up to 300VC*
*for 1s

Strong Resistance Against High Vibration

High Level Of Robustness

The S8VK-S power supply is designed to handle severe vibration conditions up to 5G. Its high level of robustness eliminates precious time spent for re-torque.

Global Safety Standards
And Marine Approval

With a wide range of certified safety standards to meet global requirements, the S8VK-S power supplies provides reliable application in many countries around the world.
