EAC-3S
Three-Phase Linear AC Source
Linear 3-phase AC/DC source up to 30 kVA with precise mains simulation and programmable curves.
The EAC-3S series is a linear 3-phase AC/DC power source designed for high-precision grid simulation and demanding laboratory, R&D, and test applications. The series covers a power range from 750 VA up to 30 kVA and supports AC, DC, and AC+DC operation for realistic simulation of single- and three-phase networks. With output voltages up to 700 VAC / 1000 VDC per phase, variable frequency from 1–2000 Hz, and selectable waveform shapes such as sine, square, triangle, or user-defined waveforms, the system is ideal for grid simulation, compliance testing, aerospace, and automotive applications. The linear amplifier design ensures very low distortion, high control accuracy, and stable output signals. Advanced features including programmable waveforms (WAV), script control, datalogging, external synchronization, and galvanically isolated analog interfaces enable complex automated testing and stand-alone operation. Optional interfaces such as LAN, RS232/485, USB, and IEEE allow seamless integration into automated test environments. Typical applications include grid simulation, compliance testing, EMC pre-compliance, aerospace electronics, railway systems, and industrial development test benches.

Programmable AC Power Supplies EAC-S & EAC-3S: High-Precision Grid Simulation and AC Mains Emulation for Industrial Test Fields and R&D Laboratories
The EAC-S and EAC-3S series are programmable AC power supplies designed for highly precise simulation of international utility grids in development, quality assurance, and industrial test environments. With power classes from 250 VA to 10,000 VA, freely parameterizable waveforms, and high signal purity, these systems are ideal for demanding grid simulations and realistic power supply testing.
The combination of precise wave-table technology, flexible frequency selection, comprehensive measurement acquisition, and industrial interface integration creates a robust platform for laboratory applications, automated test systems, and three-phase environments. In addition to standard 50 Hz and 60 Hz simulation, 400 Hz grids as well as optional frequencies up to 2000 Hz can also be realized.
Key User Benefits
Typical Applications
Simulation of international utility grids with 50 Hz, 60 Hz, and additional freely adjustable frequencies for global product testing.
Validation of onboard power components with an extended frequency range up to an optional 2000 Hz for specialized aerospace and marine applications.
Use in highly repetitive test cycles for quality assurance, design validation, and production testing of electronic assemblies.
Targeted simulation of mains disturbances using the DIP function with precisely definable phase delays for validation and robustness tests.
