The unit can be controlled with an applied voltage (5-30 vdc) or a contact closure switch connected to the Phoenix connector terminal block. The connector can also be used to cascade multiple units or provide status to a central controller.

The SX20 NE/RT provides guaranteed surge protection and power conditioning for audio, video, broadcast and computer equipment. The units are 20-amp load-capable, 12" x 12" x 4" NEMA enclosures and meet code for use at the service entrance, sub-panels and in ceiling plenums.

The unit features both common mode and normal mode Impedance Tolerant EMI/RFI filtering as well as SurgeX ICE -Inrush Current Elimination for a comprehensive power conditioning solution.

SurgeX Advanced Series Mode technology is superior to conventional MOV circuitry or MOV-Hybrid designs and is completely non-sacrificial. Our zero let-through technology provides the most reliable protection available. It stops all surges up to 6,000 volts (unlimited surge current) without producing harmful side effects such as ground contamination or common-mode disturbances.

The SurgeX SX20 NE/RT has remote control capability for use in AC power distribution systems and can be interfaced with a sequential controller such as the SurgeX SEQ.

    The SX20 NE/RT shall be housed in a magnetic shielding NEMA steel enclosure. It shall operate from 120 volts AC and have a barrier strip accessible through knck-outs in the enclosure for hardwiring power input and output connections. Overall dimensions shall be 12.0" H x 12.0" W x 4.0" D. Weight shall be 12.0 pounds.

    The unit shall have remote turn-on capabilities enabled by a hardwired connection to a separate terminal block within the enclosure. Remote turn-on and turn-off shall be activated by either a contact closure or applied DC voltage. There shall be an output voltage source for connection to a remote LED status indicator and a relay output for control and cascading.

    The SX20 NE/RT shall have a load rating of 20 amps at 120 volts, a self-test circuit with visual indicator and provide EMI/RFI filtering. It shall meet Federal Grade A, Class 1, Mode 1 guidelines for powerline surge suppressors and withstand at least 1000 occurrences of surge pulse voltages up to 6000 volts.
