Wescon Products

The ACU provides flexible multi-circuit monitoring for bus bars, feeders, switchgear, motors, generators and power distribution panels. Wire once to the ACU and see the same data at both local control panel displays and the control center(s).

The P2C™ Dual Core processor architecture makes it all possible.

Key Features
Techinical Specifications

Economical metering for 3-phase feeders, switchgear and power distribution panels .
Bi-directional power metering for co-generation monitoring
Up to 30 AC inputs per module for convenient monitoring of motor control centers. Daisy chain ACUs for even more circuits.
Multi-circuit design provides single connection point for easy wiring to field terminations
Distributed display panels don't need field wiring connected directly to them allowing easier, more flexible placement in control panels / switch boards
Integrated metering for display panel and SCADA interface so on-site staff and control center see the same data at the same time.
Integrates easily into existing GE D20, D25 or D400 SCADA systems.
