AC Specifications


	Maximum Surge Current:		Maximum current allowed for a single impulse waveform with continuous voltage applied. This level is used to indicate the protection capacity of a particular surge suppressor design, and when specifying a suppressor for a given application. For example, in a high exposure application with very large transients present from lightning, a higher-level surge current capacity would be required.

	Search Logic:		All matching products will have a value greater than or equal to the specified value.

	Clamping Voltage:		The surge protective device's (SPD) DC clamping voltage is typically much less than its AC clamping voltage for multiple outlet type spuds (Typically <300 for phone, <35 for TV).

UL Specifications


	UL 1449 L-N Rating:		UL 1449 (Ed.2) Voltage Rating: UL 1449 is a standard that covers transient voltage surge suppressors (TVSS) intended for permanently connected, cord-connected and direct plug-in applications. UL Standard 1449 established various values for Suppressed Voltage Ratings (SVR). This specification includes a requirement that surge suppression devices be marked with the surge let-through voltage for a specific UL test. By assigning a UL voltage rating for a particular mode (i.e., N-G), it can be inferred that this mode is protected against surges. For the three-wire, single-phase branch circuit (commonly used in the U.S. and Canada), the power transfer potential, L-N, is called the Normal Mode. Sometimes this mode is also called the Transverse Mode. Any voltage measurement taken with respect to Ground (N-G and L-G) represents Common Mode potentials. These are sometimes abbreviated L=N-G.

	UL 497A Rating		UL 497A is a specification for telephone surge suppression devices. These requirements cover secondary protectors for use in single or multiple pair-type communications circuits, not cellular phones.
	UL 1459 Rating		This specification covers telecommunications (telephone), such as telephone answering devices, residential telephone instruments, telephone dialers, cordless phones, key systems, and private branch exchange equipment, intended to be electrically connected to a telecommunication network that has an operating voltage to ground that does not exceed 200 V peak, 300 V peak-to-peak, an d 150 V rms.
	UL 452 Rating		This specification covers antenna-discharge units for radio and television receiving equipment and amateur radio-transmitting and -receiving equipment.

Features


	Outlet Features
	Your choices are...
	Hospital Grade		The SPD is approved and recognized by UL as Hospital Grade. Hospital grade surge protective devices have to pass additional safety tests performed to measure leakage current.
	AC Adapter Spacing		The electrical outlets are spaced in a manner that allows multiple AC adapters to be plugged in as well.
	Continuously Live Outputs		The SPD unit has dedicated outlets that are continuously powered despite SPD status (ON/OFF). This allows power to flow to the dedicated outlet regardless of unit status.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Performance Features
	Your choices are...
	Self-Diagnostics		System is able to perform internal checks to ensure it is properly grounded, powered etc.
	Status Indicators / LEDs		LEDs can give an indication of Ground Tests, Surges, Faults etc.
	Resettable Circuit Breaker		The SPD can trip an internal breaker to protect the device against excessive surges. The SPD can be manually reset once corrective action has been taken.
	Thermal Fusing		Wiring may overheat and become a fire hazard if excessive current is passed through such wiring. Thermal fuses are installed and if equipment malfunctions, continuous surges or user error causes too much current to flow through a wire; the fuse will blow to prevent the wire from overheating.
	Audible Alarm		On occurrence of a surge, an audible alarm is activated.
	Sine Wave Tracking		Surges are attenuated and dissipated as part of a normal power sine wave.
	Surge Counter		A physical count of the number of surges handled by the device. Remote alarm contacts.
	Remote Alarm Contacts		These contacts can be used as switches to provide remote status indication of the SPD performance and status.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Technology



	Your choices are...
	MOV		Metal Oxide Varistor (MOV) is a commonly used technology with high-energy capability, good reliability, and consistent performance. They have a non-linear clamping curve and fatigue rapidly at higher amperage levels.
	Silicon Avalanche Diode		Silicon Avalanche Diodes (SAD) are most frequently used in data line protectors and on circuit boards as static protectors. High clamping voltages, but limited power-handling capacity and is easily destroyed by the power levels encountered in typical power line surges.
	Silicon Thyristor Diode		Silicon thyristor diodes are gated diodes used predominately for the protection of telecom systems.
	Gas Tube		A gas tube has two electrodes that are held at a close distance so that high voltages arc through the gas within the tube, thereby clamping the voltage. They provide higher energy capability than either MOV or diodes. Gas tubes are very slow, but can handle very large surges.
	Hybrid		The hybrid attempts to incorporate all the major advantages of many of the individual components while collectively overcoming their individual faults.
	Other		There are various other SPD components that are less commonly used including; spark gaps, selenium, Zener diodes, etc.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
