Risbabh EM94-Z-V3-M-D, Panel Mount DC kWh Meter, Class 0.5, 50-150mV Shunt input, 201-1000VDC, 2 Alarm/Pulse Outputs, RS485 & USB Comms, Single Line LCD Display,10-60VAC/DC Aux Supply, Internal Logging

• 2 Pulse/Alarm Outputs
• 50-150mV Shunt Input, and nominal voltage 201-1000VDC
• RS 485 communication up to 57,600 bit/s
• USB Port
• 8MB Internal Storage
• DC Measurement Only

 

The meter is intended for measuring, analysing and monitoring DC Power. The meter records TRMS value according to the principle of fast sampling of voltage and current signals. A built-in microprocessor calculates measurands (voltage, current,, energy, power.) from the measured signals.

Application Notes

1)Reading Data from Registers -> Download file

2)Maximum Memory Size -> Read below

Max Available Memory Locations in 8MB Size = 273030

Actual parameter stored in Each log (Memory locations used) = Date +time+Number of parameter selected by user

Considering your example for 2 parameters:

Number of parameter selected by user = 2 (kwh & kVA)

Actual parameter stored in Each log = 1(Date) +1(time)+ 2 (Parameters) = 4 (memory locations used per log)

Maximum log that can be stored = Max Memory Location/Actual parameter stored in Each log =273030/4= 68257

Timelog Interval setting = 15 minutes

Log in one day = (60 /Timelog Interval setting) * 24 =(60/15)*24 = 96 Logs

Max Days = Maximum log that can be stored / log in one day = 68257 / 96 = 711 days = 1 Year & 11 Months = 23 Months.
