ACP30 Series General Four-quadrant AC Drive
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.
ACP30 Series Explosion-proof Drive Core
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 Tri-Level Control Technology
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.
Open-Loop Vector Control of High-Power PMSM And Electromagnetic Rollers
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.
New Hardware and Software Control System
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.
