Precision power
and test equipment.
Rial Electronics designs programmable DC power supplies, electronic loads, and power electronics test instruments engineered for laboratory and production environments where measurement integrity matters.
Capabilities
Four-quadrant power conversion
Source and sink architectures for bidirectional testing of batteries, motor drives, and regenerative loads. Built around SiC switching topologies and isolated control.
Precision metrology
Low-noise analog front-ends, calibrated current sensing, and high-resolution data acquisition designed to meet the standards of metrology-grade instrumentation.
Programmable control
Hardware-timed waveform synthesis, deterministic protection chains, and remote interfaces compatible with industry-standard automation environments.
Thermal and mechanical design
Forced-air thermal architectures with isolated dissipation chambers and rack-mountable enclosures. Designed for sustained continuous-power operation.
Safety and compliance
Designed in accordance with IEC 61010 and EN 61326 conducted/radiated emissions standards. Galvanic isolation and full insulation coordination on all hazardous-voltage interfaces.
Custom configurations
Application-specific variants for research laboratories, OEMs, and production test cells. Engineering collaboration on voltage range, control interface, and form factor.
Products under development
Four-Quadrant Programmable AC/DC Source & Sink
A single instrument that sources and sinks energy in all four electrical quadrants, with a programmable output spanning DC to 3 kHz at full scale — well into the audio band. One platform for power-supply characterisation, battery emulation, regenerative load testing, transient response measurement, and arbitrary waveform power synthesis.

Electronic load series
Programmable electronic loads with constant-current, constant-voltage, constant-power, and constant-resistance modes. Designed for power supply characterisation, battery testing, and production validation.
Power electronics test fixtures
Modular test platforms for converter characterisation: switch-node measurement, gate-drive validation, and double-pulse testing of discrete and module-level power semiconductors.
Engineering focus
From first principles
Every converter is designed from the topology up. Power stages, magnetics, control loops, and protection chains are specified by our engineering team and verified across the full operating envelope before production release.
Measurement integrity
The value of an instrument is the truth of its measurements. We design analog signal paths, calibration procedures, and telemetry pipelines to deliver verifiable accuracy from first-power to ten-year service.
Wide-bandgap power
Silicon carbide and gallium nitride switching at the core of every new design. Higher efficiency, smaller magnetics, faster control — translated into instruments that are quieter, cooler, and more capable than their silicon predecessors.
Built for the lab
Rack-mount enclosures, serviceable architectures, documented interfaces, and long-term parts availability. Designed to live on a bench or in a test cell for a decade.
