Product Description

Product Description

SJKQ2 Manual/Automatic Dual-Use ATS Automatic Transfer Switch

The Dual Power Automatic Transfer Switch (ATS) is an intelligent electrical switching device designed to automatically transfer power supply between two independent sources (e.g., grid and generator) during outages or voltage fluctuations. Engineered for uninterrupted power supply (UPS) in critical applications, our ATS ensures seamless load transition (<100ms) while preventing backfeeding and phase imbalances.

Key Features:

     - Voltage Range: Compatible with AC380V,50Hz

     - Current Rating: 16A~1600A

Working Principle:

The ATS continuously monitors primary (Priority) and secondary (Backup) power sources via built-in voltage sensors. When the primary source fails or deviates beyond ±15% of rated voltage, the control logic:

     - Detects fault via microprocessor (32-bit ARM Cortex core)
     - Issues break command to the active contactor
     - Engages alternate source after 0.5~30s adjustable delay (prevents nuisance tripping)
     - Auto-reverts to primary power upon stabilization (with configurable hysteresis)
Safety Interlocks:

     - Mechanical & electrical interlocking prevents simultaneous closure
     - Built-in overvoltage/undervoltage/phase-loss protection
