- We are planning a power monitoring system for a new computer facility. The
- facility will house a combination of mainframe and workstation-class machines,
- all operating from either single-phase 120V or three-phase 120Y/208V buses.
- The monitoring equipment must be configurable (exception levels, activation,
- etc.) remotely via RS-232/422 or ethernet. The purpose of the monitoring
- system will be primarily to allocate "blame" for computer system anomalies to
- power line glitches, with secondary emphasis on diagnosing power system
- problems.
-
- So far, we have looked at the Dranetz 626R event monitor. This is a 5-slot
- mainframe unit, with plug-in modules available for a variety of power
- monitoring needs. The unit communicates with a local terminal or remote host
- via RS-232, and is controlled by issuing simple ASCII commands. The 626R will
- probably meet or exceed our needs, but a fully-stuffed unit costs around $10K.
-
- Does anyone have experience with Dranetz equipment, or with similar equipment
- from other manufacturers? Please respond by email if possible; I'll post a
- summary if there is significant interest.
-
- Thanks in advance,
-
- Steve
