Frequently Asked Questions
Everything you need to know about defence and aerospace electronics repair with Synchronics.
We repair automation and control electronics from all major OEMs used in defence and aerospace — Siemens SINUMERIK CNC controllers and SINAMICS drives, Fanuc 0i/30i/31i CNC and servo amplifiers, ABB ACS880 drives and IRB robot controllers, Bosch Rexroth IndraDrive servo systems and ctrlX controllers, Honeywell avionics test bench controllers and APU boards, and BHEL/BEL radar power supplies, sonar electronics, and communication system controllers.
Yes. We repair BHEL and BEL radar system high-voltage power supply boards, sonar transmitter and processor modules, communication system controller cards, and power converter modules at the component level. All repairs undergo rigorous functional testing with detailed root cause documentation suitable for defence maintenance records.
Yes. Flight simulator and test bench electronics are a core repair area. We service Bosch Rexroth IndraDrive motion controllers for full-motion simulator platforms, ABB ACS880 multidrive modules for engine and component test benches, and Siemens SINAMICS drives for environmental test chambers. Each repair is load-tested under simulated operational conditions.
Most CNC controllers, drive modules, PLC boards, and power supplies are returned within 48-72 hours of receipt. OEM replacement boards from overseas suppliers take 12-20 weeks and cost significantly more. Our component-level repair is the faster and more economical option, with a 6-month written warranty and full root cause analysis report.
Yes. We serve defence PSUs, DRDO labs, HAL divisions, private defence manufacturers, and aerospace MRO facilities across all major defence and aerospace hubs — Bengaluru, Hyderabad, Pune, Delhi NCR, Chennai, Nashik, Lucknow, Chandigarh, Goa, and Mumbai.
