MicroMax GPS350 Interrupter by American Innovation

The GPS350 helps operators ensure corrosion mitigation effectiveness and meet regulatory requirements.

Description

The MicroMax GPS350 is a portable, flexible, rugged, fully- programmable GPS synchronized current interrupter that is designed specifically for cathodic protection (CP) surveys. The GPS350 helps operators ensure corrosion mitigation effectiveness and meet regulatory requirements. It is the smallest interrupter available with a built-in relay, keypad, and LCD display and is designed to fit inside most rectifier cabinets. The built-in relay can interrupt AC or DC up to 60 A with on/off cycles of less than 4 seconds, 80 A with cycles totalling 4 seconds or longer, is solid state, and normally closed. The GPS350 is programmed using the embedded keypad or with a PC via USB. It operates in continuous, daily, dated, and interference modes to fit any interruption schedule. The device can be powered from an AC or DC source for quick installation and reliable operation. 

Interruption for:

• Rectifiers
• Foreign bonds 

Key Benefits
 

Portable

The GPS350 is the smallest interrupter available with a built-in relay, keypad, and LCD display. It is light, weighing about 3 pounds, but rugged enough to withstand the harshest conditions.

Compact

The unit is small enough to fit inside many rectifier enclosures or magnetically clamp to the bottom, reducing the chances of vandalism and eliminating the need to chain it down to prevent theft.

Flexible

The GPS350 can interrupt either AC or DC, up to 60 A with on/ off cycles of less than 4 seconds, and 80 A with cycles totalling 4 seconds or longer. Installation is easy as polarity is not a concern.

Complete Isolation

The built-in relay is optically driven, ensuring that the interrupter is isolated from high energy events such as lightning strikes.

Transient Voltage Suppression

The GPS350 contains a unique voltage suppression technology that absorbs the inductive energy released during on/off switching and allows the relay to switch much higher currents than previously available.

Interference Mode

Synchronously interrupts specific groups of rectifiers to determine the influence of each rectifier on the structure under test. The GPS350 provides Interference Mode for close interval, depolarization and DCVG surveys with configurable Off, On, and delay settings.
