Panel Type Surge Filter
DIN-rail Surge Filter
Two-Port Surge Filter
Prosurge’s surge filter is used to protect single/three phase electrical distribution systems, especially to protect sensitive electronics against the harmful effects of transient surges. These surges are the result of:
• Direct and indirect lightning strikes
• Power company load switching
• Upstream load switching at other facilities
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’s 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.
