Power Quality Solutions have announced the availability of the PQube power quality and power quantity monitor from Power Standards Laboratory, USA.
The PQube Power Monitor measures voltage disturbances and steady state trend values data on a standard SD card. It has been designed to be built into equipment and switchboards to provide a quick source of data to assist in resolving equipment malfunctions and operating parameters in any application where continuity of power supply is important.
Using the optional Ethernet module the PQube power quality and power quantity monitor can email disturbance event notifications including attachments of time stamped RMS and waveform event pictures (GIF format) and CSV Excel compatible files.
The PQube power quality and power quantity monitor stores data and performs calculations in accordance with the latest global power quality measurement methods standard IEC & AS/NZ 61000-4-30 to the highest or Class A requirements. Sampling rate is 256 samples per cycle. No special software is required – all data is in CSV Excel compatible files.
Text based set-up files are prepared off-line and transferred to the SD card manually or through the optional Ethernet module. For those users that require assistance with data analysis and interpretation, Power Quality Solutions can provide these services.
The PQube power quality and power quantity monitor is modular and mounts on a standard DIN rail and can take operating power from 24V AC and 24 to 48V DC as standard. Using the optional Power Supply module, 100 to 240V 50/60Hz can be used.
Voltage monitoring input connections can be 1-ph, 3-ph delta, 3-ph star/Y and split-phase with nominal input voltages between 100-690V L-L (69-400V L-N) 50/60Hz with auto power configuration.
Voltage disturbances recorded include sags/dips, interruptions and frequency variations. One digital and two ±60V analogue inputs and one relay contact output are provided as standard.
User ‘snap-together’ options include:
- Power Supply module
- Ethernet module
- Temperature/humidity probes
- 1A and 5A current transformer inputs
- 20A and 100A direct wired line currents
Options for voltage harmonics, voltage flicker, current harmonics, impulses to 1 microsecond, GPS for precision timing, serial RS232/485 communications, 400Hz supplies, Zigbee wireless communications and additional relay outputs will soon be available.
