Modular power meter: RoCo, current sensing module.


RoCo1065AN; RoCo2065AN; RoCo2110AN:

This Rowgoski coil based module can be used as a stand alone module, or connected to the Volt1000.
In stand alone, the module is directly connected to the MODBUS-RTU, and can only measure currents. In combination with the Volt1000 it calculates the voltage, current, real power, apparent -, reactive -, cos(φ), Power-factor, total harmonics, and separate counters for consumed and generated power.

The RoCo module, have 4 Rogowski coils (current sensors) clicked around the (L1,L2,L3,N) power cables.
A version with 3 coils (L1,L2,L3) can be supplied on request. If the space between the cables is small, then the Cube can be an alternative

Where the RoCo2065 and RoCo2110 are designed to measure over- or high current's, while the new RoCo1065AN (available September 2023) is optimized for low currents too.
