The Model SPD Series (Surge Protection Devices) are designed to protect sensitive electronic equipment from the harmful effects of transients and RFI/EMI interference.
Models are configured for either parallel or series installation or can be either din rail or wall mounted. Units are rated as Type 4 SPDs for application in Type 1-2 locations making the SPD Series the idea choice for incorporation into control cabinets to protect PLCs, irrigation systems, Alarm and Security systems, POS terminals, CNC Machinery, and most other sensitive microelectronic based equipment.
The Model SPD Series units are self-contained in rugged plastic enclosures and employ twenty millimeter (20mm) MOVs as their key suppression elements. A green LED is provided as a status indicator identifying power on. Units are line load sensitive and interface with the incoming power cables via screw terminals (barrier strips) capable of handling conductors from #22 to #8 AWG, depending upon application and current ratings.
It is recommended that SPD units be interfaced directly between incoming power cables and located as close as possible to the equipment requiring protection. Units are intended for incorporation in a suitable enclosure.
