High performances solenoids for pull action (E-D) and push-pull action (ES-DS)

• Main features
• Double coil Elettrostart
• Single coil Elettrostart
• Special Elettrostart

The Elettrostart solenoids offer high performances both of force and of stroke (up to 50 mm) in relation to the sizes fairly reduced.
The pull coil by the high power (intermittent duty) is able to guarantee a force greater than the traditional single coil electromagnets.
The Elettrostart solenoids usually are used for the stop and the acceleration of diesel engines.

There are two versions:

• Double coil Elettrostart solenoids (E-ES) with two winding (continuous duty):

1) POWER coil, that is energized only in the initial phase to move the plunger;
2) HOLDING coil, that stays energized in continuous duty during the following phase to keep the plunger at the end of the stroke.

The passing from the first phase to the second one is possible by:

• - an internal switch, which has pressed from the plunger at the end of stroke. So it’s important the setting of the stroke to get the bottom.
• - an external electronic timer (IE04), which after the initial phase switches off the power coil. This solution is to prefer in dusty or salty environments for his sealing construction (saltcellar cars, mines, etc.) and for repeated accelerations of the engine (refrigerator cars, aerial platforms, etc.)

• Single coil Elettrostart solenoids (D-DS), that have only the POWER coil. In this case the time of energization must be short in order to don't cause the overheating of the solenoid (intermittent duty). They could be used to switch off a diesel engine when energized (for example in the boating and in the gen sets for emergency).

Remarks:

• The Elettrostart solenoids in the power phase have a high absorption of current (up to 50A). So the most common applications are on diesel engine or in general where a battery for motor vehicle is present. In the other cases you need to verify the available current.
• Since in the first phase the power is high, also in the models with continuous duty (E-ES), the cycles of energization could be repeated with a frequency suitable to don't cause the overheating of the electromagnet.
