GLASSMAN Product Lines We Repair
Our engineers are trained on the full GLASSMAN product range. Below are the major product families we service.
EH Series — High Voltage Regulated Power Supplies
Glassman EH series delivers stable, regulated DC output (5 kV to 50 kV+) with low ripple and excellent load regulation. Common faults include zener diode breakdown, transformer saturation under load surge, and compensation circuit drift causing voltage instability.
EL Series — Low Ripple High-Voltage Supplies
Ultra-low ripple designs (typically <0.1% RMS) for sensitive applications like X-ray systems and electron microscopy. Prone to LC filter capacitor aging, rectifier stage noise coupling, and feedback loop oscillation under transient load changes.
EI Series — Industrial Process Control Supplies
Compact, industrial-rated high-voltage supplies for semiconductor processing, plasma generation, and ion implantation. Typical failures include corona discharge in potting compound, HV connector arc-over, and filament transformer secondary winding insulation breakdown.
Modular Frame Systems — Stacked Multi-Output Supplies
Glassman modular architectures stack multiple regulated outputs for complex industrial systems. Common issues: inter-module crosstalk, shared transformer core saturation, and ground isolation failure between isolated output stages.
AC High-Voltage Power Systems
Glassman AC supplies deliver regulated high-voltage sine-wave output for specialized applications. Failure modes include output transformer saturation, varistor bank failure, and PFC circuit malfunction under Indian industrial power grid fluctuations.

Common GLASSMAN Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GLASSMAN equipment arriving at our workshop.
- ✓Arc-over and corona discharge in HV section — Glassman equipment operating in high-humidity Indian environments or contaminated with dust particles causes breakdown of potting compound insulation and HV connector surface tracking. Moisture ingress accelerates corona initiation at sharp edges.
- ✓Transformer primary winding burnout and core saturation — Loose transformer laminations, aged core insulation, or sustained over-voltage from Indian grid transients cause excessive magnetizing current. Filament transformer secondaries are especially vulnerable to short-circuit and insulation breakdown under load surge.
- ✓Output voltage ripple and instability (>0.5% deviation) — Aged or failed zener diode reference in regulation circuit, LC filter capacitor drying, or broken feedback sampling resistor causes closed-loop control to drift. EL series ultra-low ripple designs are sensitive to feedback linearity loss.
- ✓Filament transformer secondary insulation failure and arcing — Repeated thermal cycling in Indian industrial environments causes filament transformer secondary insulation to crack and age. Shared core with primary side can couple high-voltage transients into low-voltage filament winding if insulation degrades.
- ✓Control board failure and reference drift — Glassman control circuits use precision analog comparators and reference ICs sensitive to thermal drift and aged electrolytic capacitors. Indian heat and humidity shorten capacitor life, causing output voltage creep and control instability.
- ✓Inter-module isolation and ground loop issues (modular systems) — Glassman modular frames with isolated outputs suffer isolation resistance degradation, ground plane contamination, or failed opto-coupler isolation barriers between modules. Shared transformer secondary creates common-mode coupling paths.

Frequently Asked Questions — GLASSMAN Repairs
Do you repair Glassman equipment anywhere in India?+
Yes. Synchronics repairs the complete Glassman high-voltage power supply range — EH, EL, EI series, modular systems, and AC supplies. We offer pan-India door-to-door pickup and repair service from our facility in Vadodara, Gujarat. We handle pickups from semiconductor fabs in Bangalore, medical device plants in Mumbai and Pune, and research labs across Delhi, Hyderabad, and Chennai within 24-48 hours of fault notification.
What is the typical repair turnaround time for Glassman power supplies?+
Synchronics delivers most Glassman high-voltage power supply repairs within 5-7 working days, including comprehensive diagnostics, component replacement, high-pot testing, and output validation. Urgent jobs in semiconductor fabs can be prioritized for 48-72 hour turnaround. We provide detailed repair reports with before-after ripple and regulation measurements.
Why does my Glassman EL series ultra-low ripple supply show increasing output ripple over time?+
EL series supplies are sensitive to LC filter capacitor aging and feedback network component drift. Indian humid environments accelerate electrolytic capacitor degradation, increasing ripple above the 0.1% RMS design specification. Synchronics replaces aged capacitors, recalibrates the feedback network with precision components, and performs ripple verification on calibrated oscilloscopes to restore original <0.1% ripple performance.
Can Synchronics repair Glassman modular stacked high-voltage systems?+
Yes. Synchronics has extensive experience with Glassman modular multi-output frames, including isolation transformer failures, ground plane contamination, and inter-module crosstalk issues. We map each module individually, repair isolation barriers, re-establish proper grounding, and perform full system voltage validation across all isolated outputs. We also handle custom integrated racks with multiple Glassman supplies.
Do you stock Glassman replacement components like zener diodes, transformers, and capacitors?+
Synchronics maintains a curated stock of critical Glassman components including precision zener diodes, matched sampling resistors, LC filter capacitors, opto-coupler isolation modules, and transformer kits. For obsolete or hard-to-source Glassman parts, we source from authorized distributors and OEM contacts within 3-5 days. We always use component specifications matched to original Glassman design requirements to ensure long-term reliability in your equipment.
How do I send my GLASSMAN 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 GLASSMAN 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 GLASSMAN 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 GLASSMAN 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.
