New Arrival: LMGQ-63VA Intelligent ATS Dual Power Automatic Transfer Switch
New Arrival: LMGQ-63VA Intelligent ATS Dual Power Automatic Transfer Switch
Key Product Advantages of LMGQ-63VA ATS Dual Power Switch

1. Dual Independent Digital Display for Normal & Backup Power
- Left screen: Real-time monitoring of Normal Power (L1/N1) – displays AC voltage (red digits) and grid frequency (green digits) simultaneously
- Right screen: Live reading of Backup Power (L2/N2) – instant visual feedback on secondary power source status
No more guesswork about input power health. Installers and end-users can instantly spot low voltage, overvoltage, or missing backup supply at a glance, drastically simplifying troubleshooting for solar hybrid systems, generator backup, and dual mains setups.
2. Fully Automatic & Manual Adjustable Switching Logic
- Timer function: Adjustable switching delay to avoid frequent source toggling during fluctuating grid power
- M mode setup button: Configure overvoltage, undervoltage, and fault trip thresholds
- Up/Down adjustment keys: Fine-tune switching delay, protection trigger values without complex wiring
- Cut Both N&L full pole disconnection: Cuts both live and neutral lines during power switching for maximum electrical safety, compliant with international wiring standards
3. Clear Multi-Status Indicator Lights for Quick Diagnostics
- L1: Normal mains power active indicator
- L2: Backup power supply active indicator
- Timer: Delay switching in progress signal
- Fault: Over/under voltage, phase loss, or internal protection trip warning
Built-in fault alarm light minimizes maintenance downtime for commercial buildings, server rooms, solar off-grid systems, and rural power unstable regions.
4. Compact DIN Rail Mount & Standard Wiring Terminals
- Input terminals: N1, L1 (Primary Normal Power); N2, L2 (Secondary Backup Power)
- Output terminals: N, L (Single-phase load output)
Four large screw-type input terminals support thick wiring for high current single-phase AC loads, ideal for 230V household, retail shop, small factory, and solar inverter backup installations. The unit carries full CE certification for EU and global market compliance.
5. Comprehensive Built-In Electrical Protection
- Overvoltage & undervoltage protection for both power sources
- Source loss detection (auto switch to backup when primary grid fails)
- Anti-parallel interlock: Physical and electrical interlock prevents simultaneous connection of two power sources (eliminates short circuit risks between mains and generator/solar)
- Full live+neutral disconnection on fault cut-off

Ideal Application Scenarios for LMGQ-63VA ATS Automatic Transfer Switch
- Residential Solar PV Systems: Auto switch between city grid and solar battery inverter backup
- Home Generator Backup: Automatic mains-to-generator transfer during blackouts
- Small Commercial Premises: Shops, offices, cafes protecting refrigeration, POS, and lighting
- Off-Grid Rural Power Zones: Areas with inconsistent grid voltage worldwide
- Light Industrial & Server Cabinets: Safeguard critical low-power industrial equipment
- RV, Yacht & Mobile Power Systems: Dual battery/mains mobile power management
