Product Overview
The ASKQ8 Series Solenoid Automatic Transfer Switch(ATS) by AISIKAI is a high-performance PC-class, low-frequency switching device engineered for low-voltage AC distribution systems (50/60Hz, 3200A–6300A). As a critical component in dual-power supply systems, it enables smooth switchover between primary and backup power sources, ensuring uninterrupted electricity in mission-critical scenarios.
Designed to meet GB/T14048.11 standards, this ATS integrates advanced mechanical and electrical technologies to deliver reliable performance. It supports three core operation modes: fully automatic, electric, and emergency manual, making it adaptable to diverse operational needs. Certified by CCC, CE, and ISO9001/14001/45001, the ASKQ8 guarantees compliance with global quality and safety benchmarks, making it a trusted choice for industrial, commercial, and infrastructure projects worldwide.
Features
High Reliability & Ultra-Fast Switching
At the core of the ASKQ8 is its ability to minimize downtime. The transfer time between power sources (A→B or B→A) is ≤0.2 seconds, ensuring sensitive equipment in critical environments avoids disruptions. Its robust mechanical interlock design prevents simultaneous connection of primary and backup power sources, eliminating short-circuit risks and enhancing operational safety.
Built for durability, the ASKQ8 withstands a 60kA short-circuit current and boasts an impressive service life: 10,000 mechanical cycles and 6,000 electrical cycles. This longevity reduces maintenance frequency, making it cost-effective for long-term use.
Flexible Operation Modes
The ASKQ8 adapts to varied scenarios with three operation modes:
· Fully Automatic: Automatically switches to the backup source when the primary power fails, and reverts once the primary source is restored (configurable via controllers like SKR4-B).
· Electric Control: Allows remote switching via electrical signals, ideal for centralized management systems.
· Emergency Manual Override: Enables safe operation during power outages or maintenance, with built-in safeguards to prevent contact wear from improper use.
Advanced Safety & Compliance
Safety is prioritized through strict adherence to international standards. The ATS features a compact structure that saves installation space while ensuring heat dissipation efficiency. It supports 3P and 4P pole configurations and offers flexible connection options (rear connection as standard, front connection available on request), adapting to different cabinet designs.
Auxiliary contacts (2 NO and 2 NC for each power source) with capacities of AC 110V 5A, AC 220V 3A, and DC 220V 0.2A enable seamless integration with monitoring systems, enhancing operational visibility.
