HR-XF-R/G (soft start) fire pump control equipment uses a microprocessor to control high-power thyristor components to realize the functions of software start, soft stop and power saving of AC induction motors. Soft start control cabinet Soft start refers to the process in which the output voltage of the device rises according to a rule, so that the voltage of the controlled motor rises from zero to full voltage, and the speed correspondingly smoothly accelerates from zero to rated speed. Soft start control cabinet The soft start can make the pump start and stop torque curve approach the pump torque characteristic curve, and clean up the electric and mechanical starting impact of the pump and the system to the greatest extent, so that the start is reliable and stable.
