The TC320 Series General-Purpose Vector Control Variable Frequency Drive (VFD) is a high-performance, heavy-duty AC motor speed inverter engineered for industrial machinery, automated production lines, and high-torque transmission applications. Combining sensorless vector control (SVC) with flexible V/F algorithms, the TC320 series delivers smooth stepless velocity regulation across a wide frequency range alongside exceptional low-frequency torque output, effectively solving the common issues of low-speed torque loss and frequent tripping under heavy starting loads. Designed for rugged industrial environments, the TC320 features a compact engineering plastic housing with an independent internal cooling duct and aluminum heat sink. The front panel incorporates a detachable LED digital keypad with an integrated potentiometer knob, enabling convenient door-mount remote operation to monitor real-time output frequency, motor current, and running status. Beneath the protective terminal cover, the drive features comprehensive I/O terminals for multi-speed control, analog inputs (0–10V / 4–20mA), external forward/reverse switching, and RS485 Modbus communication for direct interfacing with PLCs and master automation systems. Available in single-phase 220V and 3-phase 380V models spanning 0.4kW to 5.5kW, the TC320 series is widely applied in heavy conveyor systems, CNC machine spindles, industrial fans/pumps, packaging machinery, textile machinery, and woodworking machinery—offering an optimal, highly reliable VFD drive solution for modern industrial upgrades.Covering standard models TC320-0.4KW, TC320-0.75KW, TC320-1.5KW, TC320-2.2KW, TC320-3.7KW, TC320-4.0KW, and TC320-5.5KW.
