SPI1-S Stationary GPS Interrupter
The SPI1-S is a powerful interruption controller for use with cathodic protection rectifiers. Precise timing accuracy and repeatability is attained with GPS and microprocessor technology. Interruption can be synchronized with interruption controllers produced by Mobiltex and other manufacturers. A small physical size and wide operating temperature range make this device ideally suited for installation within field rectifiers.
