FAQ
Does the ATS start the DG automatically?
ATS handles the switchover; DG auto-start is handled by the DG's AMF panel. Typical setup: ATS + AMF panel work together so mains failure triggers DG start, then ATS transfers load to DG output once voltage is healthy.
What warranty do you give?
1-year brand warranty on Techno ATS. Service through Santosh Electricals direct.
Can ATS fit in existing panels?
Yes — Techno ATS are DIN rail mount compatible. Most panel builders integrate without rework. Share your panel drawing and we confirm fit.
Sizing an ATS for your site?
Share load in kW, source type (mains / DG / solar), and panel layout on WhatsApp. Correct ATS sized and quoted in an hour.
