Features
|
・
|
Grounding not required (FU type)
|
・
|
Wide bandwidth, high attenuation
|
・
|
An overcurrent protector is used for safety.
|
・
|
This type of filters are helpful in reducing high-voltage pulse noise.
(FU type)
|
・
|
This type is especially useful for protection against lighting surge.
(SFU type)

|
Protection
|
When the protected equipment is hit with a current that exceeds the rating, the overcurrent protector activates and cuts off the power line.
You can restore the power line by pressing the reset button. However, before doing so, you should identify the cause and eliminate it.

Surge protection (SFU type)
|
| Because the filter circuit includes a surge absorber, the filter provides effective protection against lightning surge. The surge absorber can discharge electricity at as high as 500 to 800 V when suppressing surge. |
