- Industrial Application Cases
사례 1: Fan Control Renovation in Textile Factory
Traditional contactors in a textile factory suffered frequent burnout, coil overheating and high power consumption. The original AC standard-power contactors controlled 3 sets of 15kW fans.
해결책: Replaced with Schneider LC1D38BLDC24V contactors featuring low-consumption DC coils, combined with PLC for soft start and variable frequency speed regulation.
결과: Coil temperature decreased by 25%, power consumption cut by 50%, service life extended to 5 연령. Annual electricity cost saved about 8,000 RMB and failure rate reduced by 90%.
사례 2: Motor Control for Automated Production Line
Multiple 38A motors were used on an auto parts production line. Low-quality generic contactors caused frequent line shutdowns due to poor reliability.
해결책: Fully replaced with LC1D38BLDC24V contactors to unify control standards, and matched with Schneider PLC for centralized control and fault diagnosis.
결과: Line downtime reduced by 85%, 유지관리 비용 절감 70% and production efficiency improved by 15%. The low-power design lowered cabinet temperature and prolonged service life of other electrical components.
사례 3: Air Conditioning Control in Data Center
Multiple 18.5kW compressors were equipped in a large data center air conditioning system. The original AC coil contactors often failed to pull in under UPS power supply mode.
해결책: Switched to LC1D38BLDC24V DC coil contactors which adapt to DC output of UPS. The low-power design also reduced UPS load.
결과: Stable pull-in performance under UPS mode with zero faults. UPS load decreased by 30%, battery service life extended and maintenance frequency of air conditioning system reduced.
