Services
We take a specification to a manufactured product: feasibility, hardware, firmware, software, EMC pre-compliance, qualification, and series production, in one team. Complete systems or key subsystems.
Core expertise
Custom power-electronics solutions for demanding applications — from efficient converters and inverters to complex power-management systems, each optimized for performance and reliability, and designed to work as one system.
Tailored embedded systems with their own specialized hardware, firmware, and software, for intelligent control, precise measurement, and secure communication — engineered for long-term reliability and maintainability.
Advanced automation and control systems that enhance efficiency, precision, and safety — sensors, actuators, and smart control logic engineered into complete systems built around your production goals.
Your R&D partner
What we can take on for your R&D team, end to end:
Our process
We translate your specifications into a clear system concept — architecture, functionality, and design parameters that form the blueprint.
We design and develop all hardware, firmware, and software, ensuring every subsystem works seamlessly together.
We build prototypes in our in-house test center and validate every feature under real-world conditions.
Every system undergoes comprehensive functional, safety, and regulatory testing before release.
We design dedicated tools, jigs, and test fixtures that streamline production and quality control.
With everything proven, we scale to full industrial-grade production — precise, repeatable, reliable.
Case studies
Grid infrastructure
PPC Inspectra
Specialized test systems won in international bids over many years, among them an artificial ageing system for connectors of low‑voltage grid cables.

Off-grid power
Simonopetra Monastery
A DC UPS for Mount Athos: batteries feed the monastery through an inverter, and every energy source only has to charge them.

Battery testing
Sunlight
A test cabinet that loads a battery with up to 2,000 A for 30 seconds, or with a lower current for longer, and records how its voltage holds.

Send us your target specifications: voltage, current, power, quantities, and timeline. Your first engineering consultation is free.
Yes, all three, in one team, so every subsystem is designed to work with the others.
Yes. We are a design house and a manufacturer. We also design the production equipment, jigs, and test fixtures for your product.
Yes. We scale from a single prototype to a limited series or large-scale manufacturing.
Yes. Our client partnerships span decades, and the company is led today by its next generation. We engineer embedded systems for long-term reliability and maintainability, and when we manufacture a product we also build its production jigs and test fixtures, so later changes start from a known baseline.
Functional, safety, and regulatory testing, including EMC pre-compliance testing up to 1 GHz, and product qualification through verification, validation, and approval.
Yes. Our quality management system is certified to ISO 9001:2015.
Yes. Our systems have reached more than 85 countries.
