CB-2000
Features & Benefits
“Take the CB-PRO and make it better!” That is what AMR’s engineers were told to do, and they did it. A new processor core has been added with expanded memory and faster processing/sampling speed. Previously, unique firmware was installed on each unit based upon customer preferences (e.g. communications, enable/disable certain features, etc.). Now, all features are available and user selectable, and there’s room for expansion. If a customer has a set of specific settings for cable(s) or machine(s), we can set up an option where the user selects the cable or machine and all settings are preset. User interface is easier to navigate and scroll through. A backlit display is used to make the screens easier to see in low light conditions. Some customers had nuisance tripping on Phase Current Imbalance. This has been eliminated. The CB-2000’s enclosure is physically stronger and more environmentally sealed. It is a direct drop-in replacement for the CB-PRO, same exact footprint and wiring. For a detailed description and printable information, click below to view the CB-2000 cut sheet.
