NDS1.1334 - Page 1 / 2 Product Datasheet SFD2-10-100-275-A Two Phase DIN Mount Surge Filters The Novaris SFD2 range of surge Ölters is designed for protecting ×oating AC or DC power supplies. Applications include DC power supplies, balanced circuits for rail applications and single phase IT systems. Multistage Protection. The SFD2 uses 3 stages of protection to provide a low let through voltage. The Örst stage comprises a delta conÖguration of metal oxide varistors to provide clamping between both lines and between each line and earth. The second stage is a low pass Ölter providing instantaneous protection against high frequency impulses. The third stage is a line to line metal oxide varistor to provide an extra level of protection against primary and load side surges. No Earth Leakage. The SFD2 conÖguration results in zero earth leakage under normal operating conditions. The earth reference for the product is isolated using a spark gap. This means even in the event of a short circuit failure within the device, no current will pass to earth. Safe Metal Enclosure. Novaris power protection products are housed in safe, all metal enclosures. In the event of a prolonged overvoltage they will not catch Öre or explode. Installation Independent Performance. Series surge protectors such as the SSP and SFD range house the shunt (parallel) connection of the protection components internally within the device. This reduces the connection impedance to a minimum to guarantee optimal performance in all installations.
