This communicating communicating displays, measures and transmits energy production or consumption data in kWh with its analog and digital outputs to a supervision or energy management system. The 53U electricity consumption meter is easy to install and adapts to all your electrical installations: building, workshop, machine, electric charging station, photovoltaic installation...
Electricity meters are essential devices for measuring theelectricity consumption of electrical installations and equipment. Good meter management can reduce electricity bills by ensuring accurate measurement based on actual consumption rather than estimates.
The smart meterslike the 53U meter, make electricity management easier by providing automatic, real-time readings of consumption. This enables industrial companies to better understand and control their electricity consumption, contributing to more efficient management of their energy costs.
Functioning and principles of electricity meters
Electrical energy meters measure the electricity consumption of a site, building, workshop or machine.
These energy meters detect the electrical current flowing through a circuit and convert this information into a precise measure of energy consumption. Thanks to these devices, electricity consumption can be efficiently and accurately monitored to optimize energy use in buildings or industrial sites.
Electrical mainmeters and electrical sub-meters can be used to monitor all the specific electrical circuits of an industrial plant or factory.

Versatility and precision for electric meters
One and the same model can be used as a single-phase 2-wire and 3-wire electronic meter, or as a 3-phase/3-wire and 4-wire electronic meter.
Users can freely select and program the main variables such as AC voltage and current, active and reactive power, power factor, AC frequency deviation, apparent power, active and reactive energy and harmonic distortions up to the 31st.
Measured variables also include maximum, minimum and average values, 500 types in all. Up to 1800 display combination models are available.
Large backlit display
Thanks to its LCD screen with multiple displays and direct access keys on the front panel, 53U electricity meters are easy to use.
They display live power consumption and energy, as well as a large number of electrical quantities such as current (I), voltage (U), active power (P), reactive power (Q), apparent power (S) and power factor (PF).
Quick and easy connection of the electricity consumption meter
The device is easy to install and commission.
The 53U electricity meter is specially designed to protect against phase and wiring errors, and features an integrated test function. Proper wiring ensures accurate measurement of electricity consumption.
The power consumption meter can be panel or DIN rail mounted for easy and efficient installation.
Configurable inputs and outputs
The open-collector output pulse can be used to remotely monitor energy metering or trigger a limit alarm. Pulse weight can be set.
The contact output can be simulated to test the connected device.
The external open-collector input is generally used to reset the energy metering index memory.
The signal can also be monitored on a host system via Modbus, so that the host can start/stop monitoring depending on the ON/OFF state of a load (e.g. a motor running or not).
Four analogue output options (4-20mA or 1-5V) are also available instead of Modbus and Di/Do interface.
Users can choose and program four among major variables, e.g. 1 VT plus 3 CT, to be converted into analogue outputs, thus eliminating needs for four independent single function transducers.
