This page shows how a sinewave inverter is manufactured
from the design stage through to sale. Once the technical specifications
of the inverter have been established by our technical department, the
R&D department makes an initial draft. This draft is progressively
developed in order to obtain a device with low consumption, high reliability
and better support from the technical service.
Once the initial plan have
been finished, the printed circuitry is designed is performed, taking into
account the positions of the components for the definitive version: potentiometers,
push buttons and displays must all be in specific positions. Once the design
is finished, one or more circuit are built for the prototypes.
When the printed circuit
and the program are finished, the program is introduced into the microcontroller,
and the laboratory tests are performed. During the tests all the necessary
corrections are made to the program and to the circuit to make the device
fulfill all the design specifications.
While this is happening, the casing is designed and manufactured, and the design of the serigraphy (or polycarbonate) is carried out. The first complete units are then assembled in order to perform the field tests. If during these tests a malfunction is detected, the program and the circuit are modified again until all the tests provide satisfactory results.
When all field test are finished with positive results, the serial manufacturing of the inverters is started. The chasis and casings are mounted and tested in different processes, and are then assembled in pairs. Depending on the model that is being manufactured, the output voltage, the frequency and the language to be shown on the display (one out of six) are configured. The next step is to calibrate the unit and to store the calibration data (with the serial number and date) in our data base. The last operational tests are performed and the unit is closed. The final step is to introduce the inverter with its manual into the transportation box.
