Key Highlights
  • 120V, 20A 3-bank programmable sequencer
  • Surge Eliminator & Power Conditioner
  • 2 RU (Rack Unit) form factor


The SurgeX SEQ Surge Eliminator & Power Conditioner serves as a 120V, 20A 3-bank programmable sequencer, incorporating SurgeX® Advanced Series Mode® power conditioning and surge protection. The surge protection is rated A-1-1, the highest standard of the Federal Commercial Item Description for Endurance. Its 2 RU (Rack Unit) form factor features (4) Sequence Bank A, B, and C Receptacles, (2) Always On Receptacles (14 total).

Bank C (which is next to the two always-on receptacles on the rear panel) can itself be configured to be always on, increasing the number of always-on receptacles.

SurgeX ICE® Inrush Current Elimination circuitry is incorporated into the SEQ. This eliminates problems associated with inrush currents from large loads such as amplifiers. With SurgeX ICE® it is not necessary to take inrush currents into account when designing the AC power for a system, and special time-delay circuit breakers are not required; you only need to ensure that the steady-state currents of all products plugged into the SEQ are within the 20 Amp rating.

The front panel houses a two-line, back-lit LCD display which provides status information in normal use and allows interaction with menu items during programming. Also on the front panel are two screwdriver-accessible rotary encoders which are used to step through and select from a menu of items which determine the operation of the unit. The push button, when pressed, causes the unit to power up or power down. This button can be disabled if not required. The LED above the button indicates the status of the unit: when the LED is off the unit is fully powered down, when it is on the unit is fully powered up, and when it is flashing the unit is in the process of powering up or down.

An integrated AC voltmeter indicates the line voltage on the LCD display. The internal voltmeter is a peak reading type which was chosen because most electronic equipment incorporates a power supply that charges mostly during the AC peaks. Monitoring the peak of the AC provides a more useful indication of the real voltage available to the electronic equipment plugged into the SEQ.

The SEQ is microprocessor controlled and designed to be versatile and expandable. Two or more SEQs can be connected together to provide control and power conditioning for larger systems. The SEQ can also control other SurgeX products with its auxiliary relay contacts and/or its 12V DC output. All options are set via the front panel and all connections are made at the rear panel. An optional password of up to six letters may be specified, preventing unauthorized access to set-up information. All set-up information is stored in non-volatile memory.

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 normally-open contacts. The inputs can be controlled by an applied DC voltage from 5V to 30V, by a contact closure, or by different types of switch; the input selection being made during programming. The inputs and 12V output are designed to withstand incorrect connections including polarity reversal and shorts.
