ACU Multi Circuit Meter
[Configured Item]

The ACU provides a powerful multi circuit metering device in a compact package. Anywhere multiple circuits can be accessed from a common location is a great fit for the ACU.

The base ACU can accommodate up to 15 AC analog inputs. The first group of 3 inputs are dedicated for PT (voltage) inputs, the balance can be populated with any combination of voltage and current inputs to suit your application.

The ACU can be further expanded to accommodate up to 30 AC inputs with the addition of a second termination panel that is automatically added to your configuration when Option 5 is chosen.

The ACU can be outfitted with a DC analog input with the option to add a second input if the unit is equipped with two termination panels.

A built in web server is equipped standard on all ACU's. The integrated web pages give you all the data and reporting you need. View real time data anytime from anywhere using the web browser on your PC. Monthly usage reports can be downloaded to your PC with the click of a single button. Using our Windows-based WebView software a user can custom configure the web pages to suit individual needs.

For large installations, the ACU integrates smoothly into existing building management systems using common communication protocols. The ACU provides flexible external communication options with 2 RS232/485 serial ports that can be outfitted with any protocol from our library of client and server applications and a 10/100MB Ethernet interface for high speed communications.

The ACU also provides a D.20 HDLC link interface allowing direct connection to a D20 or D200 RTU.

The ACU can be equipped with up to 9 optional LED display rack mount panels provide read out of real-time analog measurements.

Since the ACU can be configured as a stand-alone unit we also offer a selection of auxiliary power supplies to supply the ACU module with its required 20-60Vdc voltage source and auxiliary supplies to provide power for the optional LED display panels.
