Polyphaser introduces the NetGuard transient voltage surge supressor for 10/100baseT Ethernet, E1 / T11, DSL, ISDN, and POE. The NetGuard is a RJ45 plug-in type protector that works well in industrial, residential, and networking environments. It is available in 5 Vdc and 60 Vdc versions ans is tested to the 8x20usec, IEC 60000-4-5; and 10x100usec, Bellcore 1089 Surge standards. (read more)

This DIN-rail-mounted transient-voltage surge suppressor uses a patented TPMOV system to provide both sustained over-voltage thermal runaway protection and shorted MOV protection (read more)

Low voltage crowbars are solid-state protection devices that rapidly sense when a DC overvoltage is occurring and switch rapidly from an "open" to a virtual "short" circuit. Potentially destructive energy from transients is provided with a very low resistance path around sensitive components. (read more)

Transient Voltage Suppressors (TVS) are semiconductor devices designed to provide protection against voltage and current transients. The silicon Transient Voltage Suppressor (TVS) is designed to operate in the avalanche mode and uses a large junction area to absorb large transient currents. Operation of Transient Voltage Suppressor... (read more)

Equipment level DC surge protectors are designed to protect up to 15A of continuous DC load current. The MCG-12A---MCG-130A installs at or within equipment such as DC servo mechanisms, fire alarm monitoring systems, security system controls, telecom and datacom systems, etc. and provides compact, heavy duty surge suppression.
