Circutor CVM-E3-MINI
Compact three-phase power analyser with energy per tariff, per phase and harmonics up to the 31st.
The Circutor CVM-E3-MINI is a compact power analyser that measures three-phase voltage, current, power and energy in switchboards and distribution panels. This Modbus RTU template reads power, energy per tariff and per phase, THD and harmonics, and lets you reset counters and change transformer ratios and alarm settings from ModbusCloud.

Send your device list
If a device is not in the library yet, we build the template for free as soon as we have the register data.
Use cases
- Show voltages, currents and power of each feeder on a dashboard per switchboard.
- Send an email when the voltage THD on a phase rises above a limit you choose.
- Compare consumed and generated energy per tariff and per phase over months in the 365-day history.
- Track maximum demand to see whether a connection is close to its contracted capacity.
- Clear the energy counters remotely after a change of tenant or installation.
Installation
Connect RS485 A(+), B(-) and the shield S of the meter to the ModbusCloud Gateway and terminate both ends of the line.
In the setup menu, choose protocol Modbus and set peripheral number, speed and parity. Defaults are 1, 19200 baud, no parity, 8 data bits, 1 stop bit.
In ModbusCloud, add a Modbus device with the same settings and import the Circutor CVM-E3-MINI template.
Check that L1 Phase Voltage and L1 Frequency show plausible values and that the currents match the load.
Things to watch for
The meter does not answer. What should I check?
Check in the setup menu that the protocol is Modbus and not BACnet, and that peripheral number, speed and parity match the Modbus device in ModbusCloud; the default is 19200 baud without parity. Then swap A and B and check the termination at both ends of the line.
Why does a single setting not change when I write it?
The meter only accepts writes with function 10 and applies new settings after a reset. The five transformer ratio registers must be written together in one message; a single register is rejected. Change ratios on the meter itself if a group write is not possible.
Why are there kWh and Wh registers for the same energy?
The meter gives each energy counter as a register in kWh (or kvarh, kVAh) and a register in Wh (varh, VAh). Use the k-unit register for dashboards and history; compare both on the display if you need finer resolution.
What should I watch out for with the delete commands?
Delete commands clear maximum values, maximum demand, hour counters or energy counters at once and cannot be undone. Read the counters you need first. Writes to the configuration also restart parts of the measurement after the reset, so plan them outside critical moments.
