SJKQ5 ATS Dual Power Automatic Transfer Switch

The SJKQ5 ATS Dual Power Automatic Transfer Switch ensures uninterrupted power supply for critical systems, supporting 20A-3200A loads at AC400V with 500-800V insulation and 6-8kV impulse withstand. Engineered for high-demand applications, this dual power switch features rapid transfer times (0.6-2.4s) and multiple utilization categories (AC-33A/B/iB/CB). With short-circuit making capacity up to 67kA and control voltage options (DC24V-110V/AC220V), the SJKQ5 ATS operates efficiently across industrial and commercial environments. Its robust design includes low power consumption (55-600W) and compact weight (3.4-67kg), ensuring reliable performance in backup power systems requiring seamless source transition.
