Surveyor
The E-MAX Portable DFR/DDR monitors voltages, currents and digital (event) inputs in an electrical power system environment to detect and record out-of-limit conditions. When such a condition is sensed, data including a specified prefault period is captured and stored in the recording system. The Recorder transmits the data automatically or on command to one or more locations.
The Recorder has non-volatile solid-state drive storage for data retention.
All functions are controllable at the Recorder site as well as remotely from any site with compatible equipment and software. The Recorder has security functions to restrict remote access to authorized users.
Accessories include a Portable Touchscreen Monitor, a lightweight travel case, with or without wheels and an optional accessory kit to convert the E-MAX Portable quickly and easily to a standard 19” rack mount unit.
