Prosurge’s surge filter
Prosurge’s surge filter is designed as a 3-stage protection system which consists of primary protection & secondary protection with
a well-designed LC filter in series. The LC filter is used to slow down the inherently fast rise rate of voltage and current.
The primary protection module is used to divert the strong lightning/surge current, while the secondary protection module & LC filter
will limit the let-through voltage to a very low level.
The surge filter should be installed in series with the supply powering the equipment.
