Features

50A and 100A versions.

Easy to use.

Extremely compact and lightweight, fits in tight areas, no orientation requirements.

On/Off ranges between 0 to 100 seconds.

Reverse Polarity Protection.

300-hour battery life from two D cell batteries, or can run continuously from CP supply.

Fully microprocessor controlled, automatically stores the last ten used setups and stores up to 10 Waveforms.

Master/Slave synchronization as standard.

Radiodetection patented GPS synchronization is standard. Permits synchronization of any number of interrupters remote from each other. Permits 24-hour timer operation.

Advanced power electronics mean cool running even at high ambient temperatures.

Can generate 4 Hz & 8 Hz for compatibility with Radiodetections Precision Pipe Locator.

Software upgrades via RS-232 socket.

Over voltage, current and heat protection.

User replaceable leads.

Can be used as a conventional 50A or 100A interrupter as well a generating unique signatures for the Radiodetection Stray Current Mapper (SCM) System.
