Power-One has introduced the ACC Controller, a network-power-system controller providing monitoring and management of an array of parameters, and an extensive alarm log, enabling the collection and analysis of critical data needed to facilitate energy saving and increased system reliability.
Site-level DC power system parameters that can be monitored and controlled, locally and remotely, include DC voltage, rectifier current, rectifier temperature, system capacity, circuit breaker status, and a range of battery information.
The controller features a simple ‘plug-and-play’ design, and a self-guided setup sequence to simplify installation. Remote alarm monitoring is via USB, or RS232, using web-enabled PowCom software. An Ethernet port enables control over a TCP/IP network and the Internet. Alarms can be mapped via SNMP traps to customer OSS platforms.
Additional features include multilevel password protection with user-defined profiles, remote firmware upgrades, audible alarms, low-voltage disconnect, temperature compensation with programmable compensation factors, monthly data logging, and front-panel LCD display and buttons that enable on-site service without the need for a PC.
ACC Controller compatibility includes Power-One’s Guardian Series of network power systems. Rack and cabinet configurations are available to deliver up to 500 amps with up to 720 Ah of backup battery capability. Medium and large DC power plant requirements are also supported with 1200 A per bay, up to 6400 A total.
