 2.- PRODUCT DESCRIPTION

CVM-NET4+-MC

 is an instrument that measures and calculates the main electrical parameters of 

three-phase (balanced or unbalanced) and single-phase industrial power networks. 

It measures effective (RMS) values, using three alternating and neutral voltage inputs and can measure 

up to 4 circuits with three current inputs (through current transformers In / 0.250 A) .

The device features:

One button

, used to restore the device's default communication parameters.

-

 

2 indicator LEDs: CPU 

and

 COMM�

- RS-485

 communications,

 

with the

 MODBUS RTU®

 protocol

- 4 digital relay outputs�
