3 Phase Network Analyzer with DIN Display | UPM309RGW

3 Phase Network Analyser with Rogowski coils - Overview

UPM309 is an innovative instrument for the measurement and recording of electrical power parameters. It is particularly suitable for consumption analysis and control, with an excellent quality/price ratio. Connections are quick and easy, useful for retrofitting applications on existing switchboards or for an energy audit.

UPM309 is the ideal instrument to establish the measurement points on the plant. The instrument communicates with an RS485 serial port by MODBUS RTU/ASCII protocol or through an Ethernet port by MODBUS TCP protocol.

Furthermore, it is available with WintoolNET software for remote management. The web interface is also available with an Ethernet port option: a very useful function that gives the option to manage the instrument by any PC connected to the network.

Electrical Installation Meter with Power Analyzer | MPI-540

Electrical Installation Meter - Overview

The MPI-540 meter is designed for checking the safety of industrial and domestic electrical installations. The user has the option to register the parameters of electrical networks located at these facilities. This allows for the measurement of the parameters for protection against electric shock using a single universal device while verifying the quality of electricity. The Auto mode allows significant automation of measurements of the meter and makes it possible to test the functioning of residual current circuit breakers, as well as in pre-programmed measuring sequences, which can be extended with their own sequences. Automatic measurement of insulation resistance of 3-, 4- and 5-wire conductors is possible by using an additional AUTO ISO-1000C adapter.

Power Quality Analyzer | PQM3000

Power Quality Analyzer PQM3000 - Overview

The PQM3000 is a high-end power quality analyzer which is able to monitor and record the major power quality parameters. It provides accurate measurement and voltage characteristics are monitored according to Class A specifications. It can also act as an event/fault recorder, capable of storing a high number of voltage events and disturbances, frequency variations, inrush current, etc. Additional PQ data can be recorded, such as Flicker, Unbalance, Harmonics and Interharmonics, and Mains Signalling. It also provides standard power measurement data for three-phase systems. Extra voltage and current measurement channels allow additional monitoring of Neutral Potential and Earth Leakage current.

PQM3000 is available for external standard CTs with 1 or 5A output. In this way, maximum flexibility is granted even in existing plants.

The powerful recording features can capture and record all types of standard and PQ data simultaneously. This can be recorded for a long time due to the high memory capacity. In this way a complete EN 50160 analysis can be performed. Events and disturbances also provide waveform recording together with RMS values. Recordings can be transferred directly through a web interface or set as an automatic scheduled data upload to a remote server.

PQM3000 includes different communication ports so the user can access them in different ways. The Ethernet ports on the front and rear panels allow complete control on the instrument such as web access for real-time monitoring, device setup, stored data transfer, and maintenance operations. The external mobile network router gives the possibility to manage the device via a 4G network if the Ethernet communication is not available (router sold separately). The RS485 port is dedicated to the data reading of PQMGPS1, i.e. the external GPS module provided with the instrument. PQMGPS1 provides accurate time information regardless of the location of the installation in a distributed monitoring system.

Moreover, different I/O channels are provided to enhance the instrument features. A user-friendly multilingual interface is provided for the webserver which simplifies access to instrument functions.

Power Quality Analyzer PQM3000 - Features
- Rack 19” mounting
- Harmonics and inter-harmonics measurement

Power Quality Analyzer PQM-702

Power Quality Analyzer - Overview

The Power Quality Analyzer PQM-702 is a high-tech device providing users with features to measure, analyze and record parameters of 50/60 Hz power networks and power quality in accordance with the European Standard EN 50160. Analyzers are fully compliant with the requirements of IEC 61000-4-30:2015, Class A.

The device is equipped with five voltage measurement inputs installed as cables terminated with banana plugs marked as L1/A, L2/B, L3/C, N and PE (ground). The voltages measured by four measurement channels are up to ±1500V (the device has two voltage sub-ranges). This range may be increased by using additional external voltage transformers. Current is measured using four inputs installed on short cables terminated with probe terminals. The terminals may be connected to the following probe types: flexible claps (marked as F-1(A), F-2(A), F-3(A)) with nominal rating up to 3000 A (differing from others only by coil diameter); clamps F-1A6, F-2A6, F-3A6 with a nominal range up to 6000 A and hard probes marked as C-4 (range up to 1000 A AC), C-5(A) (up to 1000 A AC/DC), C-6(A) (up to 10 A AC) and C-7(A) (up to 100 A AC).
