LOAD PULSE UNITY
More than just a meter …
The LPU 3P is a counting interface and a measurement recorder. Conventionally, it serves as a pulse energy meter for a three-phase + neutral network.
It records the values measured and calculated on the average of the phases and on each phase, as well as the analog and external pulse values collected on these other inputs.
It has two pulse outputs which can be configured each on one of the physical quantities measured: Wh, VAh, VARh.
The measurement period of the recording is adjustable at will (default 10 minutes).
For each measurement period and for each quantity measured, the LPU counter stores 3 values:
Recorded electrical quantities:
Coding switches allow you to define without a computer:
An acquisition unit
It has 4 digital inputs which can be extended for synchronization of measurements with tariff information (Top 10 min, etc.) and / or pulse counter information.
It is possible to add 2 analog or 4 digital inputs to it for the acquisition of measurements or counters.
Communication via RS485 bus. With the LPU-E1 option, a USB or Ethernet connection is possible.
The CKS utilities software allows the complete configuration of the counter and allows the live display of all the measured variables. U1 / U2 / U3 – I1 / I2 / I – Cosø, power per phase and power for 3 phases (active, apparent, reactive)
temperatures …
The LPU 5200 stores its measurements and actions over a period of several weeks. Open to all communication modes (Com, PSTN, IP, 4G, LTE), these data are readable, usable and can be analyzed using our LEO or Coviewer software.

SYSTEM ACQUISITION MODULE
The SAM modules record analog and counting information in steps of 1 minute to 1 hour. They are used for monitoring consumption, for permanent measurement readings and for the possible transmission of alerts in the event of thresholds being exceeded.
The data can be read, used and analyzed using our LEO or Coviewer software. Retrieved by our servers, their data enters the services
consumption alerts to monitor the operation of the installations.
Communication takes place via RS485 bus (5m) or with the SAM-E1 option with a
USB or Ethernet connection (RJ45). Up to 32 SAM modules can be connected via RS485 bus and share Ethernet communication.
The AKS stores its measures and actions over several weeks.
