It’s found that electronic equipment is sensitive to both the absolute magnitude of the impulse voltage and its rise rate. The radical changes in dv/dt and di/dt, rather than the peak voltage, is the major source of electronic circuit damages.
Prosurge surge filter is designed as a 3-stage protection system which consists of primary protection & secondary protection and 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.
