MULTI CIRCUIT DC CURRENT MONITOR (16 CHANNELS)

Model MCM-1600PV

Measuring･display of DC current values generated by PV systems and DC load

current of related apparatus in multi circuit successively for a long term as well as

memorizing the average current values between the intervals, of which data can be

transmitted to PC in Excel File.

The circuits to be measured are max. 16 lines and in PV systems, can measure DC

current per each string unit at the same time.

Using clamp type current sensors which enable safe and easy operation.

MEASURE･MEMORIZE･DISPLAY THE DC CURRENT OF MAX.16 CIRCUITS AT THE

SAME TIME

EASY FOR DATA MANAGEMENT (STORAGE BY CSV FORMULA)

GENERAL

1. MEASURING FUNCTION

By Connecting Optional CT Sensors, the instrument can measure and memorize DC

current of 16 circuits at the same time and the memorized data can be seen even during

measurement.

2. LOGGING MEASURING FUNCTION

This instrument displays and memorizes the average current between the selected

intervals.

Interval : 1 / 5 / 10 / 15 / 30 / 60 minutes

Contents of Memory : Measuring Time / Measuring Circuit / The average current value

Capacity of Memory : Approx. 20,000 data (72 days with 5 minutes interval)
