The inverter in a plastic bag would be protected by two EPE buffers in a carton independently. And then each packed item would be stacked up on pallets if the quantity is large.
S3800 series was R&D independently by Sanch R&D team in 2013, widely applied to many different industries because of it's general functions. It adopts vector control with speed sensor/without speed sensor, dynamic torque vector control and V/f control.
Higher control performance
Variable control modes: vector control with speed sensor/without speed sensor , dynamic torque vector control and V/f control.
Quicker response: quicker response to current and speed.
Longer durability to overloading: High Duty (100% in 3 sec. 150% in 60 sec.), applied to general purpose; Normal Duty (120%in 60sec.), applied to fan and pump etc.
