PQT 90 is a Power Quality Transducer which offers to the

user many advantages and solutions:

• Quick assembly and maintenance using Plug and

Play modules.

• Load failure prevention: harmonic analysis (A/V) with

source detection and control; up to 4 alarms for a

powerful variable control;

Alarms logging and data stamping.

• Remote control facilities: up to 4 pulse outputs, up to 4

analogue outputs, RS485, RS232 port

• Energy cost allocations with independent import/export

and multi-tariff active/reactive energy meters

• Water and gas metering and communication using the

same instrument.

The main applications where the PQT 90 can be fully exploited

• Electrical parameters analysis, control and utility metering in

the medium and heavy industry.

• Electrical parameters analysis and utility metering in the

public buildings and shopping centres particularly when

there is the need to collect the data from many buildings in

different locations by means of PqtSoft.

• Electrical parameters analysis and local control in the

unguarded sites with remote centralised supervision

capability using GSM communication and PqtSoft data

acquisition system.
