Repairs & Testing

• High and low frequency power converters: Our repair specialists are highly experienced in servicing high- and low-frequency power converters, where accurate fault identification and safe repair procedures are critical. We apply advanced test equipment, simulation tools, and real-time analysis techniques to diagnose issues such as switching failures, control-loop instability, component breakdown, and thermal stress. DTS not only repairs failed hardware but ensures that repaired units meet the same performance and reliability standards as new systems.

• Thyristor phase-controlled systems: DTS is also a trusted expert in the repair and testing of thyristor phase-controlled systems, where precision timing, accurate firing control, and rugged power hardware are essential. Our engineers and technicians restore firing circuits, gate-drive systems, protection modules, cooling assemblies, and control electronics with meticulous attention to detail. Through comprehensive testing—including load simulation, synchronization verification, temperature monitoring, and dynamic response analysis—we ensure each system operates safely, efficiently, and consistently under industrial conditions.

• Induction heating systems: With extensive experience in high-frequency applications, DTS provides specialized repair and full performance verification for induction heating systems. These systems are highly sensitive to component integrity, resonant tuning, and thermal behavior, making expert diagnostics crucial. Our services include restoring inverter stages, resonant tank circuits, IGBT and MOSFET power modules, capacitor banks, high-frequency transformers, cooling systems, and embedded control electronics. DTS conducts detailed analysis of resonance drift, load coupling performance, thermal cycles, and power delivery patterns to ensure restored systems deliver stable, efficient, and repeatable heating performance. Whether used in forging, hardening, melting, or industrial process heating, our repairs ensure long-term reliability and optimal energy efficiency.

• High-voltage switch-mode power supplies: For advanced applications, DTS also offers full service capabilities for high-voltage switch-mode power supplies. These units require disciplined safety procedures, accurate high-voltage measurement techniques, and deep knowledge of switching topologies. Our technicians perform component-level repairs, reconstruct high-voltage stages, verify insulation integrity, and analyze system behavior under controlled load conditions. Each repaired supply undergoes rigorous HV testing and functional validation to ensure complete operational readiness.

• Power Control Systems: Our repair services extend to all forms of industrial power control, focusing on component-level repairs and system recalibration to guarantee safety and performance under continuous load.

• Communication Interface Systems: We troubleshoot and repair industrial interface boards, using specialized testing equipment to verify communication integrity across RS-485, MODBUS TCP/IP, CAN bus, and Ethernet protocols, ensuring seamless data exchange and isolation protection.

• Human Machine Interface (HMI) Systems: To support complete system restoration, DTS also services Human Machine Interface (HMI) systems, repairing display modules, touchscreens, communication ports, power supplies, internal electronics, and embedded software issues. We ensure HMIs are fully functional, responsive, and reliable—ready to provide operators with clear, accurate control and feedback.

• Advanced Testing with Custom Test Benches: In addition to component-level repair capabilities, DTS specializes in the design and manufacturing of custom test benches to support both in-house repairs and client-specific testing requirements. Our custom test benches simulate real operating conditions, enabling precise evaluation of repaired systems before deployment. From load banks and controlled power sources to communication analyzers and automated testing scripts, these benches ensure every repaired product is validated with utmost accuracy.
