Single-Phase Soft-Starters for up to 3 hp from Carlo Gavazzi
The fully solid state starters are simple and easy to set up, requiring just two user adjustments: the motor ramp-up time and initial torque, which can be independently adjusted via the built-in potentiometers. A green LED indicates supply voltage presence. The ramp-up and full-voltage indication are provided through an orange LED. The starters do not require a dedicated control signal, so less wiring is involved. Despite their simplicity, the devices can help reduce motor starting current by 40% compared to a direct on-line start. Features include all solid-state design with no bypass relays; universal 120-240 VAC line voltage rating; control by line voltage; option for AC or DC supply voltage; maximum current rating of 12, 16 or 25 amps; up to 10 starts per hour at rated current; and CE approval and, cULus listing.
