Product Overview The TJ-FOC-C700T-SPIN-1 dual-speed FOC DC brushless centrifuge driver board is developed and manufactured by Tianjiao Electronics, adopting Field Oriented Control vector technology with high/low dual-speed switching drive capability. It features wide speed regulation range, stable torque output and smooth low-noise operation. Supporting 110V/220V wide voltage compatibility, this driver board integrates 220V door-opening output, 220V refrigeration NO/NC output and display board communication interface, with Hall sensor and three-phase wire connections for brushless motors, as well as brake resistor interface for braking function. It is equipped with multiple protection mechanisms including over-current, over-voltage and over-temperature protection. Featuring low power consumption, strong anti-interference capability and controllable temperature rise, it supports long-time continuous stable operation. Fully function-tested with aging process before delivery, it is a reliable drive control accessory for 700W class dual-speed centrifuge equipment.
