As everyone knows that inverter is widely used for elevators or escalators, and there are many different inverter brands, such as Fuji, ABB, YASKAWA, Mitsubishi, Schneider, SIEI, and so on. Today, we are discussing what is the difference between ‘AVY4221-EBL BR4‘ and ‘AVY4221-KBL AC4-0‘ of SIEI inverter.
‘AVY4221-EBL BR4‘ is used for gearless host, which is synchronous.
‘AVY4221-KBL AC4-0’ is used for geared host, and which is asynchronous.
If you want to order SIEI inverter from ElevatorVip.com, please provide some information at your jobsite to us, such as model, host type (gearless, or geared), etc., and then we will help you to select the right model. Other questions are also asking us. Thank you!
