Our take on the SurgeX SEQ

Professional-grade power protection for your home

SurgeX provides power protection for many of the top arenas, stadiums, and concert halls in the country. (Including Carnegie Hall and the Cowboys' stadium.) In other words, venues that: (A) absolutely can't afford to have power failures and (B) require the cleanest power for pristine audio and video. SurgeX now offers power protection for the home, so that you can expect the same level of reliability and quality for your essential gear.

Product Highlights:

  • designed to be mounted in a component rack system
    • rack size: 19" (2U)
  • front-panel LCD display
  • allows you to power up and power down components in sequence rather than all at once
  • 14 industrial-grade AC outlets on back panel (compatible with 15-amp and 20-amp AC plug)
    • three sequenced banks of four AC outlets
    • one bank of two AC outlets always on
  • two outlets can switch to outputs to control other SurgeX surge protectors and power conditioners
  • program and customize sequences and power settings
  • Advanced Series Mode surge protection can withstand up to 1,000 surges of 6,000 volts
  • advanced Impedance Tolerant® EMI/RFI filters virtually eliminates line noise
  • ICE® "inrush current elimination" technology softly turns on connected equipment to prevent harming internal circuitry

Sequencer: SurgeX Sequencers provide the sequencing parameters, conditioning, shutdown thresholds, and surge protection needed to safeguard audio, video, broadcast, and computer equipment. These units have enhanced management features and are extremely easy to install, program, and use.

A-1-1 Certified Surge Protection: All SurgeX products meet Grade A, Class 1, Mode 1 surge protection certification. Grade A guarantees protection from the worst surges normally found within a building during a lightning  strike (as defined by IEEE/ANSI C62.41-1991). Class 1 provides the best quality surge suppression, while Mode 1 guarantees that the system ground is not contaminated.

  • Survived 1,000 surges of 6,000V/3000A with no failures or degradation
  • Let-through voltage did not exceed 330V
  • Ground was not contaminated

Advanced Series Mode Surge Elimination Technology: Featuring Advanced Series Mode surge elimination technology, the SurgeX Sequencer provides premium protection for sensitive equipment that relies on audio and video performance. Its patented power protection technology is non-sacrificial and eliminates surge energy up to 6,000 Volts, without producing harmful side effects such as ground contamination or common mode disturbances that can degrade the performance of AV systems.

Non-Sacrificial: Most importantly, SurgeX Sequencers do not incorporate sacrificial components of any kind, effectively guaranteeing an unlimited service life without the requirement for testing and/or periodic maintenance.

No Ground Contamination: SurgeX Sequencers act first as low pass filters which simply block the high-frequency (HF) components of powerline surges. The remaining low-frequency (LF) surge energy is diverted into a bank of capacitors where it is stored for the duration of the event and then slowly discharged back across the incoming hot and neutral conductors without involving any connection to equipment ground. SurgeX Sequencer can thus be placed anywhere along a power circuit without the ground reference elevation disadvantage of many other surge protection devices.

ICE (Inrush Current Elimination): The SurgeX SEQ employs ICE (Inrush Current Elimination) to protect your connected equipment when they are powering up. Inrush is the initial current that occurs when a motor or electronic equipment is first turned on. The inrush current is usually several times higher than the normal operating current. In the case of electronic equipment the initial inrush current occurs while the power supply charges up. Equipment with a large current draw can have an inrush current large enough to blow a circuit breaker or damage switches and relays.

COUVS (Catastrophic Over/Under Voltage Shutdown): The SX-115-RT's incorporates COUVS technology to monitor incoming AC and automatically cuts off power to connected equipment if over (145V) or under (90V) voltage is detected.

EMI/RFI Filtering: The SurgeX SA-15 utilizes advanced impedance tolerant EMI/RFI filters to virtually eliminate any line noise.

  • EMI: Electromagnetic interference is a general type of electric, radio or magnetic interference which is transmitted by conduction or radiation and can be of a very wide frequency range.
  • RF interference: Radio frequency interference is interference which is caused by radio signals.

14 Industrial-Grade AC Outlets: The SEQ has a total of fourteen industrial-grade AC outlets - three sequences bands of four (A/B/C) and two "always on". The "always on" outlets provide power as long as power is supplied to the SEQ. Bank "A" always powers up first and off last. Each AC outlet is rated for a maximum load of 15A, but the total load must not exceed 20A.

Front-Panel LCD w/ Voltmeter: The unit's front-panel features a two-line back-lit LCD screen which provides status information in normal use and allows interaction with menu items during programming.  A built-in AC voltmeter indicates the line voltage on the unit's LCD screen.

Expandable: Two or more SEQ Sequencers can be connected together to provide control and power condition for larger systems. The SEQ can also control other SurgeX devices with auxiliary relay contacts and/or its 12V dc output.

Remote Connections: A plug-in Phoenix terminal block on the rear-panel accommodates the remote control connections and also the low-voltage outputs. There are three inputs which control sequencing - one programmable 12V dc output and one programmable auxiliary relay providing normal-open contacts. The inputs can be controlled by an applied DC voltage from 5V-30V, by a contact closure, or by different types of switches. The inputs and 12V output are designed to withstand incorrect connections including polarity reversal and shorts.

Thermal Circuit Breaker Overload Protection: The SurgeX SEQ incorporates thermal circuit breaker overload protection to guard against over-heating.

9' Attached Power Cord: The SurgeX SEQ features an attached 9' power cord that is terminated by a 3-prong AC plug. The SEQ is rated for a maximum load of 20 amps.

Note: The SurgeX SEQ Sequencer will require a 3-prong AC outlet rated at 20A (not a standard 15A outlet).

Mounting Options: The SurgeX SEQ is designed to be installed in a 19" equipment rack and requires two units (2-U) of rack space. It can also be simply placed horizontally on top of a flat surface, like a piece of AV furniture, stand, or table.

Warranty Information: SurgeX offers a limited lifetime product warranty on their surge eliminators and a limited five year connected protection warranty on equipment (up to $50,000) connected to the SurgeX Sequencer.

Made In The USA: The SurgeX SEQ offers quality craftsmanship and is made in the USA.

It does not. We do have UPS units. I recommend calling an advisor on 1-800-324-9695 for a personal recommendation on one. My Bio: [ Paul  May 28, 2017 ]  Staff
