M. C. Miller offers a wide-range of current interrupters and pulse generators to satisfy a variety of cathodic protection system applications. 

All of our current interrupters operate on battery power and, therefore, connection to an AC supply is not required (other than to charge re-chargeable batteries in certain units).  Our pulse generators, however, do require connection to an AC supply. 

Also, all of our current interrupters can interrupt both DC and AC currents and they are rugged, highly-reliable and easy to operate.
