Digital DC power meter

Bidirectional measurement

DPM can measure current in both direction or just one direction.
Typical application using battery bank as base reference, the DPM data logs discharging current (negative current) & discharging Ah or the charging current (positive current) & charging Ah.

This unique capability brings in related both the negative and the positive ampere hour, peak current & etc. values.
The support of bidirectional current measurement reduces the complication on wiring and number of meter when in out current measure is needed.

Built in Bluetooth for monitoring & download by smartphones

Each standard DPM-3321 is capable of real time monitoring of charging parameters and data download by using smart phones with installed Apps.

Large internal data storage

The extra large data bank allow to store more data . It can store 30 hours data at 30 sec sampling rate or 60 hours at 60 sec or 180 hours at 180 sec sampling rate. There are 20 groups of data with selective sampling rate available, each time the DPM is powered up a new group with selective sample rate is formed.

Build-in USB for PC connectivity

This self contained DC Power Meter has built in data adapter to download logged data directly to a PC via USB.
Download data is simple with only one connection to the micro USB port of the power meter and the USB port of the PC with the provided USB cable.
