Mô tả sản phẩm

Complex designing with single-phase power supplies is no longer necessary
Three-phase 200 V Power Supplies diminish the risk of three-phase imbalance.

S8VK-WA Features 1

Full of functions for higher design efficiency
Compact body allows easy replacement.

World’s smallest class of compact body *1

This high-capacity yet compact Power Supply requires only less than half the space of the existing models.
Side-by-side mounting possible.

S8VK-WA Features 3
S8VK-WA Features 4

Our shared Value Design for Panel concept for the specifi cations of products used in control panels will create new value to our customer’s control panels.
Combining multiple products that share the Value Design concept will further increase the value provided to control panels.

The peak current (150% to the rated current) solves the issue of momentary surge of current to motor load.

Motor-driven devices such as electric cylinders carry maximal instantaneous current when they start.
When the maximum current exceeds the rated current of a power supply without Boost Current Function, overload protection is activated to limit the output current. To avoid this, you must select a power supply with a rated output larger than the maximum current.
For example, if the maximum current exceeds 10 A, as in the figure on the below, you need a power supply with a rated output of 20 A.
S8VK-WA is equipped with a Boost Current Function that allows a peak current (150% of rated output) to flow for 10 seconds, which ensures a stable startup by a power supply with a rated output current of 10 A as described in the figure on the below.

S8VK-WA Features 5

S8VK-WA solves maintenance issues
Support for efficient maintenance and quick rec overy from errors.

Have you ever had these issues in maintaining power supplies?

The equipment stopped and no output from the power supply.

Disconnecting cables and inspection with a tester is required to identify the cause, taking time and work.

Problems

・The cause is not clear.
・The failure cannot be reproduced.
・The problem recurs even after the power supply is replaced.

Built-in maintenance point indicator indicates where to start

S8VK-WA shows you the source of the problem (e.g. input/output side of the Power Supply, or the main body),
without disconnecting cables or using a tester.

S8VK-WA Features 9

LED and signal output indicates the status of the Power Supply.

When the door of the control panel is closed, you can still check the status of the Power Supply via your controller, etc.,
using the signal that is output in synchronization with the LED
This feature clarifies the error status and necessary maintenance, minimizing the downtime.

S8VK-WA Features 10

Frequent causes of output fall

S8VK-WA Features 11

LED/signal output patterns and required maintenance

Function of LED/signal

 

INPUT OK LED: Lights up when the input voltage exceeds the lower limit value of the permissible range.
DC OK LED/signal: Lights up/Signal Output , when the output voltage is more than 90% of the rated output voltage.
Iout >100% LED/signal: Lights up/Signal Output , when the output current exceeds the rated output current.
