Nortroll's complete range of power distribution products gives customers a choice of building blocks which can be tailored to offer a complete smart grid solution.

ComTroll Repeater

The ComTroll stand alone repeater is based on the same hardware as the ComTroll 155 RTU/ICU.

The repeater can be configured to route signals to specific address ranges  keeping the radio traffic to a minimum for maximum throughput.

Any Nortroll RTU can be configured as a combined repeater extending the radio coverage to outstations further out in the network.
