Automatic Transfer Switch for Dual Power Backup Control

Keep essential circuits running when the main supply drops. This automatic transfer switch moves power to your backup source without manual intervention, so your home or workspace stays active through outages and instability.

It brings steady control to dual power setups, with fast transfer performance and clear source switching that supports daily reliability.

Stay powered through every source change

✅ Keep critical devices running when the main supply fails

✅ Transfer between power sources in under 50ms for smoother continuity

✅ Reduce unwanted shutdowns that disrupt appliances and routines

✅ Use generator or solar backup systems with more confidence

✅ Fit neatly into PZ30 distribution boxes for cleaner installation

✅ Switch automatically or manually when maintenance or special situations call for it

✅ Choose from 63A, 100A, or 125A ratings to match your setup

The TOQ7 series is built for household and small commercial applications where continuous power matters. It monitors main and backup sources and activates the alternate supply when the primary one becomes unstable.

That means less waiting, less interruption, and fewer surprises during grid fluctuations. It is suited to homes using generators or solar PV systems, where a fast and organized changeover matters every day.

It supports AC400V systems at 50/60Hz and works within normal voltage conditions of 85–110%. The auxiliary circuit uses dual relays with contact converters, giving the switch clear operating logic and dependable control performance.

Choose this ATS to keep your backup power ready and your electrical system under control.
