Pioneer
Variable Frequency Drive
Pioneer provides dependable and accurate control for asynchronous AC induction motors. It incorporates space voltage vector control, a DSP system, and both V/F and sensor-less vector control (SVC), offering 150% torque at 0.5Hz and precise speed regulation with 0.5% accuracy. Designed to withstand tough conditions, it features a conformal coating and supports a wide voltage range from 200V to 440V. Additionally, it comes equipped with RS-485 MODBUS communication, a built-in potentiometer, and compatibility with an external keypad.
