The SEQ is a 120V 20 amp three-bank AC power sequencer incorporating SurgeX® power conditioning and surge protection. The surge protection is rated A-1-1, the highest standard of UL 1449 Adjunct Endurance Testing. The two rack-space steel enclosure is designed to be installed in a 19 inch equipment rack. A total of fourteen 120V receptacles are provided on the rear panel, two of which are always on, with the remaining twelve configured as three sequenced banks of four receptacles, labeled A, B and C. The front panel houses a three-line back-lit LCD display which provides status information in normal use and allows interaction with menu items during programming. Also accessible on the front panel are two screwdriver accessible rotary encoders which are used to step through and select from a menu of items controlling the operation of the unit. There is a red push button which can be used to power up or power down the unit from the front panel. This button can be disabled if not required. A built-in AC voltmeter indicates the line voltage on the third line of 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 actual voltage available to the electronic equipment plugged into the SX2120-SEQ.
