AMCI Interrupter

The AMCI Interrupter is a fully programmable; schedule interruption of a single or group of rectifiers from the website. The interrupter features an LCD display with preprogrammed functions (voltage, current, P/S voltage, AC power, battery voltage, signal strength, interruption parameters) to simplify installation and verify web settings When used in conjunction with the AMCI Smart Test Station, determine the influence of each rectifier on test points along the pipeline without the need of a site visit (see Test Point graph). Interrupter is a multipurpose remote monitor capable of functioning as a stand-alone monitor/data logger, mesh node and network gateway.

Surge Protection

AMCI interrupter incorporates the latest low power techniques (some of which are proprietary designs), which enable the unit to use the latest battery technology. It operates on a small nonhazardous rechargeable Li-Ion battery with an energy density of 2.6 AmpHrs. When not interrupting, the AMCI interrupter requires only a brief 1 to 15 minute connection to A/C power each day; statistically the surge risk is much lower, 90% to 99%, when compared with a unit requiring an always "on" connection. Surge risk is further reduced with relay isolation of 15,000V at the AC input. When isolating equipment from electrical surges such as lightning transients; the typical approaches using only MOVs (metal oxide varistor) and isolation transformers will not sufficient protection. Our equipment is TOTALLY disconnected from all power sources (except optional solar) for most of the day through high voltage relay isolation. To further isolate the interrupter, an inconspicuous 3 solar panel (optional) provides a reliable power source to recharge the battery. The solar panel and battery pack have a design life of 8-10 years under normal operating conditions.

Ample power is available for real time operation - receive commands, update calibration data, alarm trip points, reporting frequencies, upgrade software, upload data files and operate as data logger without supplemental power or compromising battery life.


The AMCI Smart Test Station is available with GSM/GPRS, CDMA, or satellite telemetry. The satellite telemetry is small and compact; no need for extra power supplies (i.e. many satellite transceivers have power consumption that can be 50 times greater); does not require special installation procedures.


The interrupter is completely configurable on the AMCI website - define input parameters, alarm trip points, alarm notification (email, voice, SMS), reporting frequency. Download data in a number file formats to facilitate importing into an existing database.
