Which brands does Sai-Tech Controls supply?+
Secure Meters for energy metering, Entes for power factor correction, Metravi, Kyoritsu and Fluke for test & measurement, Invertek Optidrive for variable frequency drives and Horner Automation for PLC, HMI and remote I/O. We also deal in MECO, Kusam-Meco and Bilz. See the full brand list.
Do you supply outside Ankleshwar?+
Yes. We despatch daily to Bharuch, Panoli, Jhagadia, Dahej, Vadodara and Surat, and ship pan-India for stocked items. Distributors and resellers are welcome — ask for the reseller schedule.
How fast can I get a quotation?+
Send the make and model — or a photo of the nameplate — on WhatsApp or email. Quotations for standard items usually go out the same working day; imported or configured items take a little longer.
Can you help select the right meter or drive rating?+
That is most of our work. Share the load details, CT ratio, panel cut-out or motor nameplate and we will recommend the correct model, accuracy class and communication option — see our meter selection guide for the checklist we use.
Do you sell replacements for obsolete instruments?+
Often, yes. Send the old model number and we will identify a current equivalent with the same cut-out, range and output where one exists — this is common with analog panel meters and older insulation testers.
