About Unifive's AC Adapters Supporting Peak Load
Frequently Asked Questions About Peak Load
"The normal load of the device is around 12V3.8A, but since a motor starts at boot-up or in cycles once every few hours, a peak load occurs, momentarily drawing a current equivalent to 7A. Therefore, I would like an adapter rated at 12V7.5A, adding a margin on top of that."
In this example, the customer selects the adapter based on the maximum actual load used, adding a margin, which is a safe method for selecting a power source.
Increase in Size...
On the other hand, selecting a power source that accommodates a peak load occurring once every few hours or once a day can lead to increased cost and a larger adapter size, which often makes people feel "what a waste."
In Such Cases, Unifive's "Peak Load Supporting AC Adapters"
In such situations, we recommend our uniquely designed "Peak Load Supporting AC Adapter" series.
Depending on the model, peak load supporting adapters guarantee durability for either 1 second or 11 seconds at twice the rated current.
In the earlier case, instead of having to select an adapter rated at 12V7.5A, it becomes possible to choose an adapter rated at 12V3.8A, as long as the peak load falls within the adapter's specification range.
The series lineup ranges from 45W to 65W, which is relatively limited, but it can be used with a wide range of devices such as industrial applications under special conditions, mechatronics products, devices that use motors like printers, and products like electronic musical instruments.
Additionally, we may be able to recommend adapter implementation to customers who normally use built-in power supplies.
We can also accommodate modifications such as component replacement or spec customization, within the scope of what's feasible through consultation.
If you are interested in our products, we would be delighted if you would contact us.
