Power System Management, s.r.o. company is a distributor of measurement device of class A - PQube® producted by Power Standards Lab.
PQube® is an instrument for monitoring electric power
systems.
It is convenient to think of it as a combination of a power line
monitor, a power meter, and a digital camera – it combines the
best features of all three.
PQube records disturbances on the mains circuit:
sags/dips, swells, interruptions, frequency variations. It also
records disturbances on two analog input channels. It also records impulses, waveform
snapshots, THD, and strip charts or trends of voltages,
frequency, temperature, and humidity, and cumulative statistics
about the voltage quality.
It can monitor single-phase or three-phase circuits, at up to 400 VAC phase-to-ground (equivalent to 690 VAC
phase-to-phase), at 50 Hz and 60 Hz.
You don’t need any software from PSL to use PQube. It records all data on a standard SD
memory card, which can be read by any computer. No special software is required – just
open the GIF picture files with standard photo programs, or even Microsoft Word® and
Microsoft PowerPoint®, or open the CSV files with any spreadsheet program such as Microsoft
Excel®. Configure PQube by editing a text file on the SD card.
It includes channels for measuring auxiliary voltages – typically 24V AC or 48 Vdc.
It also has a general-purpose digital input, which you can control with switch contacts or a
logic signal, and a relay contact output, which opens for at least 3 seconds whenever PQube detects an event.
It can be directly powered from 24 VAC or 24~48 Vdc, or it can be equipped with an optional PS1 power supply
that operates from 100V ~ 240V, 50/60 Hz.
When equipped with an optional current sensing module, PQube also
records current waveforms and power. It
also records watts, watt-hours, VAR’s, power factor, and other power-related
parameters, temperature and humidity with up to two TH1 temperaturehumidity
probes.
When equipped with an optional ETH1 Ethernet module, PQube can automatically send you e-mails
whenever it detects an event. You can choose e-mails that are optimized for you to read (HTML and text), or for a
computer program to read (XML). It will automatically send picture files and spreadsheet files as attachments. And
you can send PQube a new setup file, or even update its firmware via e-mail.
