HD2000 series engineering variable frequency drives successfully replaced the original imported AC variable frequency speed controllers (models 3#, 4#, 5#, 15#, 17#, and 18#) on the main rolling production line of a certain steel high bar manufacturer in Hebei. This project was completed during the workshop overhaul period, and the replacement work was finished in a very short time. Production achieved the same output as before the upgrade and has been running continuously, stably, and reliably.
