2.英文详情介绍
Sumitomo AF503-3A7 is a transistor inverter (frequency converter) belonging to the AF-500 series, used for speed and torque control of three-phase AC motors.
Product Features
Rated capacity of 5.7 kVA, suitable for motor power of 3.7 kW (approximately 5 HP).
It has protection functions such as overcurrent, overvoltage, undervoltage, and overload detection, which can reduce the impact of abnormal working conditions on equipment.
Support adjustable frequency and voltage output, achieve motor soft start, smooth acceleration and deceleration, and reduce impact on mechanical equipment.
The control method covers basic frequency control and torque regulation, and can adapt to loads such as fans and pumps or situations that require a certain dynamic response.
Installation should ensure proper heat dissipation spacing, and input and output cables should be selected correctly and properly grounded and shielded to suppress electrical interference.
Product application areas
Pump and fan system
Air handling unit
Conveyor belts and conveying equipment
extruder
Blender and mixing equipment
Compressor
Production line transmission control
General industrial three-phase motor speed regulation scenario
