Audited Supplier ACP30 series medium voltage AC drive features high-performance vector control for general purposes. Its NPC three-level topology and two-and-four-quadrant capability can drive permanent magnet synchronous motors, reluctance motors and asynchronous motors.
>>> Product Features
The ACP30 series four-quadrant drive is for high-performance vector control in general occasions. NPC three-level topology for the 1140V and 3300V products together with AFE rectification technology for high grid, can drive permanent magnet synchro-nous motors, reluctance motors and asynchronous motors. It is designed for driving one motor with reliable durability so it's suitable for conveyor belts, hoists, winches in mining industry.
The ACP32 series high performance vector AC drives of 660V, 1140V, and 3300V, are capable of two-quadrant and four-quad-rant operation so they can drag asynchro-nous motors and permanent magnet synchronous motors. The leading motor vector control technology, controllable AFE rectifier technology and NPC three level topology together provide a complete frequency conversion solution for the coal mining industry.
High-power NPC three-level technology features low-volt-age spikes, so it's kinder to motor insulation. When the drive cable is up to 2000 meters long, it can accurately obtain the motor parameters, optimize the narrow pulse, and drive the synchronous motors in a low-frequency way with heavy load.
High-power permanent magnet synchronous motor and electromagnetic roller open-loop vector control technology locks the magnetic poles before startup to realize shock-free startup, heavy load startup, and stable low-frequency operation, so it is suitable for occasions with low carrier frequency and long-distance cables.
A new hardware and software control system is developed f or medium voltage drives, so that four-quadrant or tri-level control can be realized with one single set of control unit. The built-in synchronous and asynchronous motor models can be switched via different parameters. Short-circuit and overheat protections cover each phase. Pluggable terminals are easy to maintain and there are terminal block and fiber for options.
Rich development experience to provide customers with competitive explosion-proof drives and integrated solution for different voltage levels and various topologies.
Reliable and mature IGBT drive solution adopts single high-current IGBT, laminated busbar and film capacitors in its core components, so it's capable of long-life operation.
AFE controlled rectification technology with strong grid adaptability allows stable operation even during unbal-anced grid voltage and high harmonics, so it's green and efficient.
It is equipped with CAN communication power balancing function as standard, which features strong anti-interference. Together with control mode of speed plus torque, it has strong adaptability to different site conditions as needed.
Product design undergoes thermal simulation, electromagnetic simulation, finite element, uniform flow, heat dissipation and electromagnetic compatibility analysis, and it can be customized according to the customer's needs.
