PRODUCTS
1. PRE20 Series Regenerative AC Power Source
PRE20 Series is a rack-mount, modular AC power system with integrated source-load functionality for precision AC power testing. It supports AC input disturbance simulation, ultra-high-frequency operation up to 5 kHz, power HIL integration, and AC sinking mode for evaluating a DUT’s output stability, efficiency, and protection behavior. With high accuracy and fast dynamic response, CORTEX AC is well suited for laboratory test benches and electromagnetic-compatibility-related power testing applications.
Building on these capabilities, PRE20 Series features a high-bandwidth control architecture with fast transient response, enabling accurate replication of AC disturbances and dynamic load interactions. Fine output resolution, precise phase control, and arbitrary waveform programming ensure repeatable testing of voltage, frequency, and unbalanced conditions. Its modular rack-mount design scales from 22 kVA in 3U up to 220 kVA, making it an efficient solution for medium-power laboratory validation and compliance-oriented AC power testing.
2. PRO20 Series Programmable Power Supply System
Modular and Scalable Regenerative AC/DC Source-Load Platform
PRO20 is a modular regenerative source-load platform available in both AC and DC configurations. Built on a power-module-based cabinet architecture, it provides flexible configuration and deployment options for a wide range of power conversion testing and emulation applications. PRO20 AC scales from 50 kVA to 6 MVA, while PRO20 DC covers power ratings from 50 kW to 6 MW. Power modules can be paralleled within a cabinet, and multiple cabinets can operate in master-slave parallel for higher-power systems.
PRO20 AC is a four-quadrant regenerative programmable power supply with integrated source and load functionality. It supports RLC and P/Q load emulation, harmonic and interharmonic injection, waveform generation, and grid disturbance simulation. These capabilities enable testing of EVSE, UPS, PV inverters, PCS, and high-power front-end converters. In load mode, absorbed energy is returned to the utility grid with a regenerative efficiency of up to 94%.
PRO20 DC is a bidirectional source-load simulator supporting output voltages up to 2250 VDC. It provides solar array and battery emulation, with optional battery cycling software for expanded testing capabilities. Designed for modern PV and BESS applications, it can be paired with a high-power grid simulator to perform end-to-end grid code compliance testing of utility-scale power converters. In load mode, PRO20 DC returns absorbed energy to the grid with a regenerative efficiency of over 93.5%.
3. A Series High-Power Power Supply Platform
Scalable High-Power Battery and Grid Simulation Platform
The A Series ABS Battery Simulator and AGS High-Power Grid Simulator provide complementary, regenerative platforms for high-power DC and AC testing. ABS reproduces high-voltage battery behavior on the DC side, while AGS recreates utility grid conditions at the Point of Common Coupling (PCC) on the AC side. The two systems can be deployed independently or combined in end-to-end test configurations for R&D, performance validation, and pre-compliance testing across electric mobility, energy storage, renewable energy, and utility-scale power conversion applications.
ABS High-Voltage Bidirectional Battery Simulator
The A Series ABS is a high-voltage bidirectional DC battery simulator designed to replace physical batteries in demanding power conversion testing. It provides a maximum output voltage of 2000 VDC and supports parallel operation for system capacities up to 10 MW. From a single platform, ABS can reproduce both battery charging and discharging behavior.
Built-in control interfaces and remote software allow users to configure automated test sequences, define charge and discharge profiles, and simulate different battery characteristics. ABS is suitable for testing EV charging systems, onboard chargers, V2G systems, ESS converters, and wind and solar power converters with greater controllability, safety, and repeatability than testing with physical battery systems.
AGS High-Power Grid Simulator
The A Series AGS is a four-quadrant regenerative AC power source engineered for grid-code compliance testing of utility-scale grid-connected converters. Its tower-type architecture combines MW-level power capacity with the dynamic and electrical performance required for advanced grid simulation. Single-cabinet configurations are available from 300 kVA to 1 MVA. Through master-slave parallel operation enabled by the Digital Matrix Parallel System (DMPS) and high-speed fiber-optic communication, total system capacity can be expanded to 10 MVA.
AGS provides a controlled testing environment for utility-scale grid-following and grid-forming inverters, energy storage PCS, and other grid-connected converters by reproducing complex grid conditions at the PCC. With an optional load cabinet, the system can be extended to support SCR and X/R ratio configuration, integrated RLC grid impedance modeling for anti-islanding testing, and automated pre-compliance test sequences for IEEE 1547, UL 1741, and applicable IEC standards.
During high-power and long-duration testing, AGS returns energy to the utility grid with a regenerative efficiency of up to 94%, reducing electricity consumption, cooling requirements, and overall operating costs.
