Applications
The electronic compact starter is used mainly in the OEM-segment, whereever space is limited, long lifetime is necessary and
frequent switching is need. Applications include:
• Conveyor technology
• Logistics
• Production machines
• Machine tools
• Small elevators
• Pumps and compressors
• Solar tracker
• Snow guns
Hybrid technology
In order to achieve the greatest possible advantage, hybrid technology combines two technologies. Semiconductors switch
the motor on and off with bypass relays used while the motor is running. A microcontroller ensures the right interaction
between the components, shown in figure 1 below. Before starting the motor, all relays are opened as can be seen in figure 1.
When the relays K1 and K2 are energized, the currents I1, I2, I3 are still approx. zero, see figure 2.
