Abstract
A voltage regulator controller including three types of data logs which are operator selectable and configurable. An operator can enable data logging to occur at specific times and intervals. The voltage regulator controller includes a real time clock/calendar and interval timer to support this function. In a preferred embodiment, the controller includes an event log, a snapshot interval log and a minimum/maximum metered parameter log. Advantageously, the event log can be programmed to monitor configuration changes made from the voltage regulator controller's front panel or from a remote device. The voltage regulator controller also includes a memory card interface which enables the log contents to be uploaded to a removable PCMCIA standard memory card.
