What ETPS does

ETPS Ltd. (Electronic Test and Power Systems) is a UK-based private limited company headquartered in Chesterfield that designs, manufactures, and supplies programmable power systems and specialist test equipment for engineering R&D and industrial testing applications. The company serves engineering teams in automotive and motorsport, aerospace and defence, energy storage and renewables, power electronics/machines/drives (PEMD), marine, and physics research who need to test batteries, motors, power converters, and electrical systems under controlled conditions that accurately emulate real-world operation. Customer logos include Imperial College London, Mercedes-AMG HPP, Caterpillar, BAE Systems, McLaren, ZeroAvia, Intertek, and the University of Nottingham's aerospace propulsion research facility.

The company's product portfolio spans bidirectional DC power systems (G5-RSS, LAB-MOBI, LAB-GSS), programmable DC sources (LAB-HP, LAB-TC, LAB-DSP), high-voltage power supplies up to 100kVDC (HPS series), four-quadrant grid-tied systems (EAC-ACS-4Q), single- and three-phase AC sources (EAC-S, EAC-3S), electronic loads, battery emulators, battery cyclers, grid simulators, fixed-output chargers/inverters/converters/rectifiers, and ruggedised systems for harsh environments. Core technology centres on a modular master-slave architecture that scales from watts to 6MW, voltages up to 3000VDC, currents up to 121,680A, and 2.5MVA four-quadrant capacity. Proprietary features include a patented resonance mode technique achieving ~93% efficiency in high-voltage supplies, grid-tied power recycling that reduces energy losses from ~100% (dissipative loads) to ~7%, sense-plus voltage drop compensation, embedded function generators for complex waveform emulation, and a proprietary software ecosystem (TopControl, ACSControl, GridSim, BatSim, BatControl, CapSim, SASControl) with LabVIEW and MATLAB/Simulink integration.

ETPS operates a direct B2B sales model with application engineering support, selling hardware systems on a quote basis (ranging from thousands to millions of pounds), supplemented by a short-term rental fleet and custom integration services including ruggedisation for military applications. The company holds ISO 9001, ISO 14001, Cyber Essentials, and JOSCAR certifications, supporting procurement into aerospace and defence supply chains. Pricing is not publicly disclosed, and the company maintains a small headcount (1-10 employees) consistent with a focused, engineering-led specialist rather than a volume manufacturer.
