RoCo2000AN 4 channel current sensor
The current sensor with 4 Rogowski coils, has the following properties:
- measurement coils for 4 currents (3 phases and neutral wire);
- modbus interface.
- Two RJ45 sockets for chaining.
- DIN-rail-TS35 mounting + magnet to fix it on an iron plate.
- Measurements of current, voltage, active power (imported and exported), reactive
power, power factor, cos(phi), frequency, distortion.
- Ranges:
o 2000A rms fix input range.
o 630A, 400A, 250A, 160A, 100A, 63A, 32A auto range for I1, I2, I3 and IN
(independent selection)
- 24V power, 10mA power consumption.
- Stand-alone device: It can be connected directly to a modbus master.
- Chain mode: see 5.2

Cube1000AN 4 channel current sensor
The Cube1000 is almost identical, only the form and ranges of the current are different. This
sensor is designed for cables where the space between cables is as low as 4mm.
- Ranges:
o 1000A rms fix input range
o 320A, 200A, 140A, 100A, 63A, 32A, 16A auto range for I1, I2, I3 and IN
(independent selection)
