POWER QUALITY ANALYZER QNA500 8IO
QNA500 8IO Instruction manual 8 / 111
The advanced power handling features of the QNA500 analyzer can measure and record over 500
electrical parameters, in order to analyze and control the electrical network.
The main features of the analyzer are as follows:
• 5 voltage measurement inputs (3P+N+PE)
• 5 current measurement inputs (3P+In+Id (
Earth-leakage current ))
• Class 0.2 energy and power accuracy
• 512 samples/cycle
• Configurable capture of transients and other disturbances in the installation
• Configurable register of over 500 electrical variables
• Maximum and minimum value registers
• DIN rail or rear PANEL fixing.
• WEB Server
• 3 communications ports (RS-232, RS-485 and ETHERNET)
• Communications protocols: MODBUS/RTU, MODBUS/TCP, COMTRADE, HTTP, FTP and
ZMODEM
• Additional input and output modules to expand the performance of the analyzer
• Internal battery to guarantee the operation of the power quality analyzer in the absence of
power supply
3.2.- MULTIFIT System modules
The MULTIFIT system has various expansion modules that can expand its performance features.
The modules available are the followings:
• Base power supply and communications station (M-BASE)
• Power quality analyzer (M-QNA500)
• Energy manager and alarms for 8inputs + 8outputs (M-8IO)
Additional modules can be added to the assembly to cater for future expansion requirements. Also take
into account that each M-BASE module can power a maximum number of modules, in accordance with
the total consumption.
The following cards are available:
