The LM-5400 series comprises two unique 3-phase 600v recorders (Models LM-5410 and LM-5415) each capable of simultaneously recording 4 voltages, 4 currents with events and power consumption. The 5415 adds full power quality analysis including harmonic and waveform capture capability. The fourth voltage and current channels allow neutral-ground voltage and neutral or ground current to be recorded. The emphasis is on meeting practical power monitoring needs by providing all the features required by your front-line personnel yet at an attractive cost.

Sags / Swells

The LM-5400 series calculates rms voltage and current values every cycle and saves time-stamped event data if they are out of user specified limits. One cycle swell/sag data is then available for every event. Min rms, max rms and average rms values are stored for every storage interval. Text data on up to 3000 events can be saved.

Power Quality Analysis

The LM-5415 adds waveform capture (on event or time trigger), harmonic magnitude recording and paging (modem option required). To avoid aliasing, waveforms are analyzed at a sample rate of 128 samples/cycle and harmonics through the 25th are recorded for later trending and analysis.

Power Consumption Recording

The unit records more than 30 power parameters including KW, KVAR, KVA, True and Displacement Power Factors. The LM-5400 series uses Enetics SMART CT technology whereby each CT’s calibration data is stored on a chip in the connector. This error correction technique achieves a current accuracy of better than 0.2% for CT plus recorder combined, and better than 0.5% for power. The CT’s can be moved from channel to channel or unit to unit without sacrificing accuracy. A wide range of CT’s (including self-powered flexible CT) from 20A to 6000A are available.

Real-Time Data

Real time data is available from the RS-232 port to aid in setup verification. Voltage, current, power, harmonic readings and waveforms are updated every 7 seconds.


Ruggedized / Weatherproof / Compact

These units are ruggedized for field use with a weatherproof, non-conductive case and connectors. With its small size, low weight (3.5 lbs) and wide operating temperature range (-20ºC to +70ºC), all your personnel will be able to carry this unit and install it almost anywhere.



The LMS-5700 software consists of two major components, the database (SQL) and the charting/reporting software. The database automatically aggregates data collected from one or more designated sites. Data is easily retrieved to generate the required charts and reports. For user flexibility and extensibility, charts and reports are generated in Microsoft Excel. The Excel worksheet data file can then be exported in various formats and shared among users. Zooming and panning is available on the charts. A key advantage of using an SQL database and Excel is that it is an “open” system, you are not locked into any suppliers’ proprietary software. You can retrieve any data available from the database and/or use the Excel data to generate additional charts and reports.
