The 53U is a built-in active and reactive energy meterfor three-phase and single-phase networks, communicating, equipped with analogue outputs.
It is the ideal power measurement device for measurement and energy management applications for single and three-phase low and medium voltage electrical networks, transmitting data via its RS485 digital output to a supervision or energy management system.
Active and reactive energy meters for power distribution - Single and three-phase - Connection to current transformers up to 20,000 A - Mounted on a panel surface
Advantages of the 53U electric energy meter
Intelligent
Communicating
Quick connection
Excellent visibility
One model can be used for single-phase/2-wire and 3-wire, three-phase/3-wire, and 4-wire systems.
Users can freely choose and program major variables such like AC voltage/current, active/reactive power, power factor, AC frequency deviation, apparent power, active/reactive energy, and up-to-the 31st harmonic distortions.
Measured variables also include the maximum/minimum/average values, in total of 500 types.
Up to 1800 patterns of display combinations are available.
With its multi-display LCD screen and direct access keys on the front panel, the 53U electrical energy meters are easy to use.
They offer a guaranteed direct display of power and energy consumption and a large number of electrical values: I, U, V, S, FP.
The 53U electricity meter is specially designed to protect against phase and wiring errors and has an integrated test function.
If you make a mistake during installation, don't worry: you can fix it without starting from scratch.
The device is easy to install and commission, making it cheaper and more efficient.
An open collector output can be used for energy count, pulse or limit alarm trip.
Pulse rate for energy count can be specified. The contact output can be simulated for testing the connected device.
External open collector input is typically used to reset energy count memory. The signal can be also monitored at the host system via Modbus, so that the host can start/stop monitoring according to ON/OFF status of a load (e.g. 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.
All measured variables can be transferred to the host PC via RS-485/Modbus RTU.
Conversion factors, system configuration, interval times are programmable using the PC Configurator Software locally or remotely.
Measured values, counter values, setting data are stored in the non-volatile memory at the power off.
Save yourself much time using the free PC Configurator software (model: PMCFG) to create, save and download your own parameter settings.
