Variable Frequency Drives

Control Engineering Company offers a range of inverters and PLCs from LG industrial Systems. The iH series variable frequency drive is designed for starting torque applications with IGBT module, space vector PWM control algorithm and 32-bit DSP (digital signal processor). Built-in PI control enables cost-effective speed regulation of fans and pumps by precise flow, pressure and temperature control. The optimized current and torque control by space vector PWM algorithm and 32-bit DSP enhance power factor by exact torque calculation. iH adapts space vector PWM control algorithm which allows low THD (total harmonic distortion) and low torque and current ripples, thereby improves output voltage utility, prevents motor and inverter overheats and enhances power factor of motor. iH has user friendly interface and versatile protection functions that makes it able to maximize its capability and to operate motors without trips. The range covers: 3-phase 220 V - 40 HP to 75 HP and 3-phase 415 V - 40 HP to 500 HP.
