Description

American Innovations’ i-series MicroMax® GPS80 Interrupter is a flexible CP current interrupter with no equal. It is the smallest, proven, lowest-cost fully programmable GPS synchronized interrupter on the market. It offers a choice of programmable cycles for continuous or scheduled interruption activated by selection key or via the Bullhorn ICP remote monitoring unit. The GPS80 is compatible with all other brands of GPS synchronized interrupter or logger. Users can define and store four different programs for later recall. Cycle range is up to 999.9 seconds in 0.1 second increments. The unit automatically resumes its programmed cycle if a power disruption occurs. After hours, the unit can be set to automatically generate full CP polarization.
Interrupt AC or DC. Versatility is being able to use mercury or solid state relays, and since the GPS80 can supply 500 mA, interrupting multiple relays is no problem. The external relay configuration and the user configurable nature of the relay controller output allows for use of a standard relay supplied with the interrupter or a custom relay. Standard relays are 30A Hg, 60A Hg, 100A, 90A / 240 Vac solid state, and 100A / 100 VDC solid state. Interrupter output is user selectable and highly flexible. The output can be configured to 0V or 12V for ON or OFF. Synchronization can be set to be on the leading or falling edge of the interruption cycle.

The MicroMax GPS80 Interrupter is supplied with a GPS antenna, a 110 VAC charger, and a cycle program selector key. Just attach the antenna, power supply and relay control. Your GPS synchronized interrupter cycle will start within minutes, with status indicated by LED’s. With the MicroMax® GPS80, GPS synchronization is a breeze!

MicroMax^® GPS80 Interrupter Options
	MicroMax GPS80 Interrupter, STAND-ALONE OPTION At last, an interrupter so small that it easily fits in the palm of your hand, let alone most rectifiers. Reasonably priced, so now you can afford that GPS interrupter you’ve been trying to justify for so long. It can be permanently installed in a rectifier if that is what your CP program calls for.
	MicroMax GPS80 Interrupter, OPTION 1 Weatherproof case, rechargeable batteries, uses external relay. Do you need the versatility of the MicroMax but require it to be weatherproof with backup batteries? OPTION 1 provides functionality of the MicroMax GPS80 PLUS weatherproof rugged packaging and a 2.6A.hr rechargeable backup battery, which allows up to 8 hours of testing without an external power supply. The MicroMax GPS80 is also easily removed for use as a stand-alone interrupter.
	MicroMax GPS80 Interrupter,OPTION 2 Weatherproof case PLUS rechargeable batteries and 60A internal mercury relay with external cables to switch rectifier. If you want an all-in-one interrupter, MicroMax GPS80 is your answer. By adding OPTION 2, you are provided with an affordable, small, self-contained GPS synchronized interrupter that is ready to go! Simply connect, switch on, and GPS interruption will start within minutes. Additionally, you still have the option of using external relays in combination with, or without, the built-in 60A relay. The MicroMax GPS80 is also easily removed for use as a stand-alone interrupter.

Operation

Measures interference from multiple pipelines and multiple rectifiers, and/or measures influence from multiple rectifiers on one pipeline.

American Innovation's unique, patented Interference Mode interruption cycle enables interference testing with greatly increased productivity and ease of data interpretation. By operating in Interference Mode, it is possible to determine the influence from multiple rectifiers and capture the instant off pipe-to-soil potentials, all during a single visit to a test station!! In this mode, up to 99 GPS200 interrupters can be configured to switch multiple rectifiers so that IR-free pipe-to-soil potentials as well as the influence from each rectifier under investigation can be easily collected.

The same Interference Mode algorithm can be used on a single pipeline, using the methodology outlined above, to enable you to complete an “Influence Survey”. This methodology facilitates an accurate evaluation of each rectifier’s influence over the span of the pipeline.
