DIGITAL POWER CORP Product Lines We Repair
Our engineers are trained on the full DIGITAL POWER CORP product range. Below are the major product families we service.
DPC Modular Power Supply (MPS) Family
Ruggedized, modular power supplies rated 300W to 3kW with redundancy options. Common failures include capacitor dry-out, output regulation drift, and thermal cutout circuit degradation in high-ambient installations across Indian industrial environments.
DPC Isolated DC-DC Converter Modules
High-density isolated converters (8-300W) with 5kVDC isolation for harsh environments. Typical repair needs include transformer winding insulation breakdown, output diode failure, and PWM control IC damage from power transients.
DPC Uninterruptible Power System (UPS) Controllers
Industrial UPS platforms with intelligent switchover and battery management. Faults often stem from battery charger circuit failures, inverter IGBT degradation, and backup voltage sensing board corrosion in high-humidity Indian facilities.
DPC Voltage Conditioner / Isolation Transformer Modules
Single-phase and three-phase isolation and conditioning units for protecting sensitive loads. Repair focus includes core saturation issues, winding shorts, and control PCB failures from power factor correction circuit stress.
DPC Custom Power Distribution Units (PDU)
Rack-mount and floor-mount power distribution with metering and remote monitoring. Common failures include relay contact welding, output breaker nuisance tripping, and Ethernet monitoring module firmware corruption.

Common DIGITAL POWER CORP Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DIGITAL POWER CORP equipment arriving at our workshop.
- ✓Output voltage drift or regulation failure — Digital Power Corp power supplies employ precision feedback dividers and reference ICs sensitive to aging. Capacitor ESR rise in the feedback network, combined with thermal drift in sensing amplifiers, causes gradual output voltage decay — critical for systems requiring +/- 2% regulation.
- ✓Thermal shutdown or intermittent current limiting — DPC modular supplies use thermistor-based overtemp sensing. Connector corrosion (common in coastal and high-humidity Indian plants), thermistor drift, or thermal interface material degradation between power stage and heatsink causes nuisance shutdowns or erratic current limiting engagement.
- ✓No output or dead supply — bleeder circuit stuck — DPC power supplies include continuous 'bleeder' loads for startup stability and capacitor discharge. Bleeder resistor open-circuits or the bleeder control transistor fails, leaving the supply unable to regulate or soft-start under load, triggering protection circuits.
- ✓Isolated converter output short or load fault — DPC isolated DC-DC modules are vulnerable to secondary-side transformer insulation failure (especially in vibration-intensive industrial settings), output diode junction leakage, and control PCB short-circuits from contamination or component overstress.
- ✓Redundant PSU module non-communication or control failure — Multi-module DPC systems use shared current-share and status signaling buses (often 1-wire or UART protocols). Connector oxidation, PCB trace corrosion, and firmware desynchronization between modules cause parallel-operation faults, unequal load sharing, or complete loss of redundancy.
- ✓UPS battery charger not charging or charger overvoltage fault — DPC UPS controllers employ current-limiting and voltage-sense feedback for safe battery charging. Sensing resistor tolerance drift, charger feedback amplifier bias voltage error, or relay contact wear prevents proper charge profile execution, risking battery undercharge or overcharge damage.

Frequently Asked Questions — DIGITAL POWER CORP Repairs
Do you repair Digital Power Corp equipment throughout India?+
Yes, absolutely. Synchronics Electronics repairs the full Digital Power Corp power supply and converter portfolio across India. We offer PAN-India door pickup and delivery from major metros — Mumbai, Delhi, NCR, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata — as well as tier-2 industrial centers. All repairs are performed at our 15,000+ sq. ft. facility in Vadodara, Gujarat, with complete test infrastructure and genuine DPC replacement parts in stock.
What is the typical repair turnaround for a DPC modular power supply?+
Standard repair turnaround for Digital Power Corp supplies is 7-10 working days (including diagnostics, component replacement, full functional test, and regulation accuracy verification). Expedited 3-5 day turnaround is available for critical production shutdowns. Our engineers perform input ripple analysis, output transient response testing, and thermal cycling validation — ensuring your DPC supply meets original performance specifications before shipment.
Can Synchronics repair DPC isolated DC-DC converters, or do I need to replace them?+
Synchronics successfully repairs Digital Power Corp isolated converters. Many facilities assume converters are unrepairable 'black boxes,' but we diagnose and rebuild them routinely. Common repairs include transformer insulation restoration, output rectifier diode replacement, and PWM control IC reprogramming. Converter repair typically costs 40-60% less than OEM replacement — critical for Indian manufacturers managing tight capex budgets. We provide 12-month warranty on all converter repairs.
How do I know if my DPC power supply has a capacitor problem?+
Digital Power Corp supplies employ bulk capacitors sensitive to thermal aging and ripple current stress. Early warning signs include: output voltage slowly drifting downward under load, thermal shutdown triggering at lower ambient temperatures than before, audible buzzing from the power stage (indicating ripple current rise), or visual bulging of the can. Synchronics performs ESR (equivalent series resistance) analysis and capacitance measurement as standard diagnostics — we replace capacitors before failure impacts your production. Preventive capacitor replacement is recommended every 5-7 years in operating environments above 50C.
Does Synchronics stock original Digital Power Corp spare parts, or do you use third-party components?+
Synchronics maintains inventory of genuine Digital Power Corp certified components including modular PSU modules, isolated converter pods, control PCBs, and power stage subsystems. For standard components (MOSFETs, capacitors, diodes, magnetic components) we source industrial-grade equivalents that meet or exceed DPC specifications — verified through full performance characterization. All repairs come with detailed parts certification. For critical aerospace or defence applications, we can procure OEM parts directly through qualified distributors.
How do I send my DIGITAL POWER CORP 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 DIGITAL POWER CORP 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 DIGITAL POWER CORP 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 DIGITAL POWER CORP 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.
