Direct On Line start is probably the simplest and traditional type of start and it is to connect the motor directly to the power supply performing therefore a full-voltage start-up.
It is often abbreviated with the acronym DOL.
DOL (Direct On Line) start is the simplest and most cost-effective system for starting pumps and motors and it is traditionally the most widely used. The induced current is the rotor is high. This results on a peak current on the network which can be 5 to 8 times the nominal current.
They are suitable for startup of small submersible pumps, deep well pumps or booster sets with surface pumps.
DOL control panels need a direct connection to the power supply network, which implies:
Easy control panel is self-programming by simply pressing a button. EASY creates a local wireless network to control and refine the parameters with your smartphone or tablet. Control and protect, just do it simply with EASY.
SMART PRO is the evolution of the SMART EVO control panel, suitable for both clean water and wastewater systems. Compact, very easy to install and program also by App, it facilitates the replacement of old and obsolete panels installed.
The practical display to check the working and operation data of the motors connected distinguishes SMART PRO X. Thanks to the new expansion modules system and the connections, the panel can be used for a wide range of applications.
DRYTEK PRO protects the electric pump against dry running by the power factor control integrated in the microprocessor. Thanks to the display and the available expansions it helps saving installation time and reducing service costs.
