This meter is a little larger than our JLD404. It displays Kilowatt Hours kWh, Voltage, and Current simultaneously with large red easy to read numerals.
While AmpHours are a pretty good measure of used pack energy, kWh are actually slightly better. They are a function of both voltage AND current so as your pack voltage changes, your amp-hour rate will as well. But kWh measure both voltage and current for a slightly more accurate measure of power.
Additionally, this meter lets you monitor voltage, current, AND kilowatt hours simultaneously.
The unit features a control relay that can be triggered high or low, by voltage or current. Use the voltage function to protect your pack from overcharging.
It also features an RS232 MODBUS protocol output with measured data from the meter. In this way, it can be interfaced to Arduino, PCs, and other electronic equipment..
The meter comes with choice of shunt but can measure currents up to 9999 amps.
Voltages of 0-500vdc.
kWh of up to 9999.
Operates on 12-30vdc.
Accuracy of 0.3% full scale +/ 2 digits.
Sample rate: 8 per second
96 x 96 x 100 mm
RS232 - 9600 bps, 1 start bit, 8 data bits, 1 stop bit
Reports current, voltage, DC power, DC kWh values via MODBUS RTU protocol over RS-232
