A mains line reactor is necessary to reduce the harmonics of the mains current. The mains line reactor must have at least 4% voltage drop at rated load. Without UL /CSA Certification Mains line reactor without UL /CSA certification:

NettetIn a DC circuit (such as that of the DC bus in an AC drive), an inductor simply limits the rate of change of current in the circuit since current in an inductor wants to continue to … NettetA line reactor or a DC Choke (aka DC Link Reactor) performs roughly the same function if you are just looking at reducing line side harmonics a bit. Both will take the harmonics … buff\u0027s sf

Do the Altivar Process Drives come with a DC choke or Line Reactor ...

Nettet7. sep. 2024 · All Altivar Process Drives come standard with DC chokes. There is no need for a line reactor. The Size 7 ATV630 product and the Size 7A and 7B ATV930 products come standard with the DC Choke, but can be ordered without the DC Choke by adding a suffix MN to the part number. When not using the DC Choke a 5% input line reactor or … Nettet12. des. 2024 · Voltage spikes on the AC power lines cause elevation of the DC Bus voltage which may cause the adjustable speed drive to sense and indicate an … Nettetreactors and DC chokes when used in combination with variable speed drives to reduce the mains input current’s THD. Total harmonic distortion of the current is called THDi in this document. AC line reactor An AC line reactor is wired at the drive’s mains inputs.
