Design and budgeting of low-voltage systems

PROJEX is online software that can be used by any device connected to the Internet (smartphone, tablet or PC), with which it is possible in a simple and quick way to design and budget electrical low-voltage installation systems and boards.

Main functions offered by the software:

- drawing of the electrical scheme and insertion of the devices;

- calculation of the parameters of the electrical system;

- board configuration (manual or automatic);

- system estimation;

- printing and exporting of documentation.


Drawing of the electrical scheme and insertion of the devices

The wiring diagram drawing mode allows you to insert the symbols of the devices into the diagram by defining the connection mode (series, parallel, start of a new panel) or by dragging them directly into the circuit. The previously inserted device codes are selected by the program at the end of the calculation.

The devices can also be inserted directly without calculations by selecting them according to their electrical parameters.

The wiring diagram can be structured in three different ways.


Calculation of the parameters of the electrical system

After drawing the single-line wiring diagram, it is possible to calculate the electrical parameters of the system (load and short-circuit currents; voltage drops); the results determine the components (cables; switching and protection devices, etc.) that the program selects.

The electrical parameters of the devices are automatically placed in the diagram, the rows (data) of which can be set by the user. It is also possible to "block" all the devices and/or the cables or only those selected: during verification, the program signals any anomalies (and suggests the replacement of the blocked component with another suitable one). The photos of the devices (switches, measuring devices, signalling, command, etc.) facilitates their selection.


Board configuration (manual or automatic)

After defining the single-line electrical scheme (by calculation or by direct insertion), it is possible to configure the board in an automatic or manual way.

Automatic board configuration: with one click, PROJEX selects a complete board. The board is immediately drawn and can be modified by the user; during the modifications, the enclosure is updated in real time (drawing and price).

Manual board configuration: the software offers all the compatible enclosures with the devices present in the circuit and allows you to create the switchboard in a simple way, showing (while making the board) both the shape of the devices to be inserted (highlighting those already inserted) and the structure of the scheme (also highlighting here the components already inserted). To complete the board, it is possible to select busbar systems and accessories from those compatible with the enclosures used.

Lastly, the program carries out the thermal test, as required by the electrical board standard.


System estimation

The program allows you to obtain lists of materials (with or without price) that can be structured in various ways: general, differentiated by board, divided into the electrical part (devices) and the enclosure part (carpentry). You can also insert discounts, increases and labour.


Printing and exporting of documentation

The project documentation (diagrams, frontviews, system/devices/enclosure data, material lists) can be exported in various formats.
