Maintenance & Repair
Powerstax provides top-tier diagnostic, component-level repair, and preventive maintenance services across our full range of AC-DC switched-mode power supplies, DC-DC converters, and thyristor-controlled transformer rectifiers. Our engineers perform comprehensive root-cause analysis, thermal imaging, and load testing to prevent costly plant downtime.
- Board-level component diagnostics & stress testing
- Preventive maintenance schedules for harsh environments
- Full post-repair burn-in & safety re-qualification
Precision Calibration
Maintain precise voltage output, current limits, and telemetry accuracy with our certified calibration services. Using calibrated NIST/UKAS traceable instrumentation, Powerstax ensures your medical imaging, electrochlorination, and defense power systems remain strictly within certified operational envelopes.
- Voltage, current, and ripple measurement verification
- Digital control interface telemetry alignment
- Full calibration certification for audit documentation
Product & Systems Design
When off-the-shelf power converters cannot fulfill mechanical, thermal, or electrical constraints, our engineering design team develops tailored power architectures. From custom magnetics design to digital firmware, liquid cooling topology, and EMC pre-compliance, we take bespoke concepts from specification to full production.
- Bespoke electrical, mechanical, and thermal modeling
- EMC pre-compliance, MIL-STD & medical safety design
- Integrated firmware and industrial communications
OEM Spare Parts Management
Minimize operational disruption with rapid access to genuine Powerstax spare parts and sub-assemblies. All components are fully tested, traceable, and covered by factory warranty, preventing compatibility failures associated with unauthorized third-party replacements.
- Direct factory supply of power modules, semiconductors & control boards
- Long-term component availability & obsolescence protection
- Emergency spare kit packaging for critical installations
On-Site Training & SAT
Empower your technical teams with hands-on on-site training delivered by Powerstax engineers. We conduct comprehensive Site Acceptance Testing (SAT) for high-power transformer rectifiers and provide your team with practical fault-finding and operational skills.
- On-site commissioning and load-bank validation testing
- Safety, operation, and maintenance procedure instruction
- Customized technical manuals and diagnostic guides
Refurbishment & Life Extension
Extend the service life of existing industrial power equipment through our comprehensive factory refurbishment programs. Upgrading legacy thyristor controllers, power electronics assemblies, and cooling systems lowers total cost of ownership while modernizing control capabilities.
- Complete overhaul of transformers, switchgear, and liquid systems
- Digital controller retrofitting for modern PLC integration
- Warranty-backed restoration to original engineering standards
