Functions/features/options

The primary function of the ATC-900 is to accurately monitor power

sources and provide the necessary intelligence to operate a transfer

switch in an appropriate and timely manner. In addition, the ATC-900

provides useful real-time and historical data, reliable two-way

communications, and programming through the device’s faceplate

or Modbus RTU. The ATC-900 features digital signal processor (DSP)

technology to provide and maintain superior precision and versatility

during both programming and data access.

Standard and optional features

A variety of programmable features are available to meet a wide

array of application requirements. Individual features or feature

combinations provide the information required to tailor switches to

individual needs.

Unlike earlier controllers, the ATC-900 comes with standard features

that are ready to use, with the exception of closed transition, current

metering, and Ethernet. Another advancement is that there are four

(4) standard inputs and four (4) standard outputs that the operator

can easily program by choosing from a wide array of predefined

functions. Additional inputs and outputs can be added in groups of

four (4) up to sixteen (16) for a maximum of twenty (20) in total.
