2.4 - ABOUT THE<br />
SSW-03 PLUS<br />
The SSW-03 Plus <strong>series</strong> is a totally microprocessor controlled<br />
Soft-Starter <strong>series</strong> which controls the starting current of threephase<br />
induction motors. In this way mechanical inmpacts on<br />
the load and current peaks on the supply network are<br />
prevented.<br />
2.4.1 - Introduction This <strong>series</strong> includes models from 120 to 1400A, being<br />
supplied from 220V, 230V, 240V, 380V, 400V, 415V, 440V,<br />
460V, 480V, 525V or 575V. (The available types are listed in<br />
Section 8).<br />
The models up to 205A are fitted with forced cooling and<br />
isolated heatsink (thyristor-thyristor modules). The models<br />
from 255A up to 1400A have forced cooling and energized<br />
heatsink. (Disc thyristors).<br />
The electronic control circuit uses a 16 bit microprocessor with<br />
high performance, allowing settings and displaying by means<br />
of the interface (keypad + display) of all needed parameters.<br />
Depending on the power, this <strong>series</strong> (SSW-03 Plus) has 8<br />
different construction forms, as shown in Figure 2.1.<br />
