Key Product Features

1. Dual Mechanical & Electrical Interlock, Zero Risk Of Mains-Generator Parallel Short Circuit
   Dual interlock design completely avoids simultaneous closing of mains and generator contacts, fundamentally eliminate short-circuit accident caused by two power sources parallel connection, greatly improve power system safety.
    
2. 4P Full Four-Pole Breaking Design, Neutral Line Synchronous Isolation
   All three live wires + neutral wire cut off synchronously, no residual voltage hidden danger, fully comply with industrial low-voltage power distribution safety standards, suitable for precision instrument, fire protection, medical high-standard power supply occasions.
    
3. Fast ≤2s Automatic Transfer, Minimize Equipment Power Outage Loss
   Quick switching action after mains abnormal, effectively reduce downtime of production equipment, server, medical equipment, avoid economic loss caused by long power cut.
    
4. Built-In Overload & Short-Circuit Trip Protection, Protect Load And Generator Unit
   Independent thermal magnetic trip module, instant cut off circuit when overload or short-circuit occurs, prevent generator overcurrent burnout and load equipment damage.
    
5. Perfect Matching With Smartgen HGM AMF Controllers, Integrated Automatic Control Logic
   Dedicated control signal terminal matched with HGM series controller, plug-and-play wiring without extra intermediate relay, realize full automatic linkage of power detection, unit startup, load transfer and cooling shutdown.
    
6. DIN Rail Compact Cabinet Installation, Flame-Retardant Shell Anti-Vibration & High Temperature Resistant
   Flame retardant PC plastic shell, dustproof anti-aging, stable operation in high-temperature, dusty generator control cabinet long-term 24-hour unattended working condition.
    

Common Equipment Failures Solved

• · Single manual transfer switch requires manual operation after power outage, cannot realize unattended automatic power switching
• · Single interlock cheap ATS has hidden danger of dual power parallel short-circuit, easy to cause cabinet short-circuit fire accident
• · 3P three-pole switch cannot isolate neutral line, residual voltage damages precision control equipment
• · Old ATS contact ablation and adhesion, power supply intermittent, frequent load tripping
• · Non-matching ATS needs extra intermediate relay wiring, complicated construction and easy wiring error
