Can a single regenerative platform validate EV chargers, AI servers and renewable energy systems? The platform pushes testing beyond megawatt levels.
Caltest Instruments, a Pacific Power company in India, has introduced the AGX Series, a regenerative AC and DC power test platform designed for higher-power applications including electric vehicle supply equipment (EVSE), solar inverters, AI data centres and aerospace systems. The modular platform increases power density to 24kVA/kW per 4U chassis while enabling scalable test configurations for applications requiring megawatt-level power.
The system is intended to address the growing demand for testing high-power electrical equipment as industries adopt larger AI computing infrastructure, electrified transportation and renewable energy systems. By combining AC and DC sourcing, regenerative loading and grid simulation in a single platform, the series enables engineers to perform multiple power validation tasks using the same test setup, reducing equipment requirements and improving laboratory efficiency.
Each 4U module delivers up to 24kVA per kW and supports four-quadrant regenerative operation, allowing the platform to function as a regenerative grid simulator, electronic load, AC and DC source, or DC-to-AC source. The system scales to 216kVA per kW per cabinet and up to 1.296MVA per MW in three-phase configurations.
It also supports output frequencies up to 3000Hz, a constant-power voltage range of up to 350Vac line-to-neutral or ±500Vdc, and provides up to 48Arms per phase in three-phase operation. The series also incorporates the web-based SmartSource Suite, enabling remote configuration, monitoring and automated test execution from mobile devices without requiring dedicated software drivers.
According to the company, the platform can emulate grid conditions for compliance testing of solar inverters against standards including IEEE 1547, UL 1741 and IEC requirements, while also supporting high-current EVSE validation and power emulation for AI server infrastructure. Its modular architecture is also suited to automated test equipment used in aerospace and defence applications where flexible AC and DC power simulation is required.
