6 FAQs about [Soft start screw air compressor solution]

How does a compressor soft starter work?

The Compressor Soft Starters use a relay together with two thyristors in parallel to switch the compressor current. At start the relay is open. The starting current is limited by the thyristors. As the motor accelerates to his nominal speed the relay is closed. The nominal motor current is flowing through the relay contacts.

Does the compressor soft starter have a start capacitor?

In order to improve the starting torque the Compressor Soft Starter has a start capacitor, which is activated only while in the starting phase. In compliance with EN 60335-1 and EN 60335-2-40 as well as EN 60947-1 and EN 60947-4-2.

How does a high start current affect a compressor motor?

This high start current increases the starting torque of the compressor motor enough that the motor will start even though the refrigerant pressures haven’t equalized, or in an “under-voltage” condition. Once the compressor begins running, the voltage across the start winding increases.

How do I get my AC to start?

Solutions available: Hard Starts and Soft Starts or bigger generator. By putting a $13.00 (hard start) PTC relay capacitor on the unit it did allow for the A/C to start but after research. **** I find this solution boost the peak current possibly damaging the compressor coils.

What causes a compressor motor to start if power is applied?

This causes a very high current to go through the start winding when power is first applied. This high start current increases the starting torque of the compressor motor enough that the motor will start even though the refrigerant pressures haven’t equalized, or in an “under-voltage” condition.
