ASTRON Product Lines We Repair
Our engineers are trained on the full ASTRON product range. Below are the major product families we service.
ASTRON RS Series Regulated Power Supplies
Regulated DC power supplies ranging from 5A to 250A output. Commonly used in telecom base stations, broadcast facilities, and industrial control systems. Frequent issues include regulator IC failures, transformer burnout under load surge, and control board capacitor aging.
ASTRON RM Series Mobile/Compact Power Supplies
Compact, portable regulated supplies for field operations and temporary installations. Known for robust design but prone to cooling fan bearing wear, rectifier diode failure, and meter accuracy drift over time.
ASTRON RF Power Amplifiers
VHF and UHF RF power amplifiers used in broadcast transmitters and communications equipment. Common faults include RF final transistor burnout, parasitic oscillation, bias network failures, and power output decline.
ASTRON Linear Amplifiers
SSB/CW linear amplifiers for amateur radio and professional communications. Repair requirements include vacuum tube replacement, plate supply capacitor degradation, and RF coupling network tuning.
ASTRON Switching Power Supplies
High-efficiency switching-mode supplies for modern telecom and data center applications. Prone to PWM controller IC failure, output capacitor ESR increase, and secondary rectifier diode issues under heavy load cycles.

Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common ASTRON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ASTRON equipment arriving at our workshop.
- ✓Output voltage droops under full load current — Series pass transistor or regulator IC thermal degradation, or output capacitor ESR rise due to age and ripple current stress. ASTRON supplies commonly experience this after 10-15 years of continuous operation in hot industrial environments.
- ✓Transformer core overheating or audible buzzing sound — Lamination short circuits due to core insulation breakdown, or excessive magnetizing current from shorted secondary windings. ASTRON RS-series supplies in high-temperature Indian factories are particularly susceptible after thermal cycling.
- ✓Digital meter reading unstable or display blank — Meter circuit reference voltage IC failure, corroded LCD display connector, or low-level analog signal path noise coupling from transformer. Common in ASTRON supplies operating in electrically noisy Indian manufacturing floors.
- ✓No output after power-on, or immediate crowbar shutdown — Rectifier diode opens or shorts due to transient surge or aging; overvoltage sense circuit malfunction; or output short-circuit limiting circuit stuck. ASTRON supplies used in Indian industrial facilities with poor earthing often experience this.
- ✓RF output power declined or transmitter SWR alarm trips — RF final transistor gain loss or partial failure; bias network resistor drift; or impedance matching network component aging. ASTRON RF amplifiers in Indian broadcast stations suffer accelerated aging due to tropical humidity and dust ingress.
- ✓Cooling fan fails or bearing noise develops — Ball bearing wear and corrosion from thermal cycling and dust contamination; motor winding insulation breakdown; or capacitor-start circuit failure in older ASTRON mobile supplies.

Frequently Asked Questions — ASTRON Repairs
Do you repair ASTRON equipment anywhere in India?+
Yes. Synchronics repairs ASTRON regulated power supplies, RF amplifiers, linear amplifiers, and all industrial power electronics across the full ASTRON product range. We offer PAN India door-to-door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Surat, Kolkata, and all tier-1 and tier-2 cities. All repairs are carried out in our Vadodara, Gujarat facility with same-day diagnostic reports and fixed turnaround times.
Can you repair ASTRON RS-series supplies with no output voltage?+
Yes, absolutely. No-output faults on ASTRON RS-series supplies are typically due to rectifier failure, regulator IC malfunction, or blown fuses. Synchronics diagnostic procedure includes full power-stage testing, reference voltage measurement, and crowbar circuit verification. We replace faulty semiconductors with ASTRON-rated equivalents and test the repaired unit at full load current before return. Most no-output cases are resolved in 3-5 working days.
What is your warranty on ASTRON power supply repairs?+
Synchronics provides a standard 12-month warranty on all parts replaced and labor performed. We also offer extended 24-month warranties on major components like transformers, rectifier bridges, and regulator ICs. All repaired ASTRON supplies are burned-in under load for 8-12 hours and measured for output voltage stability, ripple, and noise before warranty commencement. Emergency repairs and on-site commissioning support are available.
Do you stock spare parts for ASTRON RF amplifiers and linear amplifiers?+
Yes. Synchronics maintains a dedicated inventory of ASTRON RF and HF components including final power transistors, tube sockets, bias network components, and output matching capacitors. We source original ASTRON parts through authorized distributors and maintain relationships with component manufacturers for tube and transistor supply. Custom-matched transistor pairs and precision capacitors are available for quick turnaround repairs on broadcast and amateur radio equipment.
Can you upgrade an old ASTRON supply for modern industrial use?+
Yes. Many Indian manufacturing plants operate decades-old ASTRON RS-series supplies in critical roles. Synchronics offers selective component upgrades — replacing electrolytic capacitors with high-reliability film types, upgrading cooling fans with sealed-bearing industrial models, adding remote monitoring interfaces, and retrofitting modern surge protection. We maintain original form-factor and output specifications while significantly extending service life. Contact our team for a custom upgrade proposal.
How do I send my ASTRON unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a ASTRON drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on ASTRON repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your ASTRON unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
