AC Power Supples and Test Solutions for AC Applications

The established and versatile TC.ACS series features advanced CV/CC/CP/RLC power waveform generation with a base frequency range of 0…1 kHz and a spectrum of harmonics up to 5 kHz. It supports full four-quadrant operation, including DC mode, and is ideally suited for a wide range of demanding laboratory and industrial applications, such as smart grid research and simulation, AC load bank operation (RLC/CC/CP), and EoL testing.

  • Power Range: 0…30 to 0…2000+ kVA
  • Voltage Range: 0…528 Vrms (L-L) (higher on request)

The TC.ACS series can be used as a full 4-quadrant grid simulator, offering multiple programmable operating modes: Power mode, RLC load mode, and current mode. Its flexibility makes it ideal for testing inverters (PVV2GESS), chargers, OBC (11/22 kVA), drives (e.g., for elevators), grid impedance simulation, and anti-islanding testing.


  • Power Range: 0…30 to 0…2000+ kVA
  • Voltage Range: 0…528 Vrms (L-L) (higher on request)

The TC.ACS series can be used as power amplifier, featuring different operating modes (CV/CC), an analog high-speed interface, and an optional digital high-speed interface based on the Aurora protocol. The fast response capability of TC.ACS provides minimum time delays and phase errors, making it ideally suited as P-HIL-amplifier for power hardware-in-the-loop simulation.

  • Power Range: 0…30 to 0…2000+ kVA
  • Voltage Range: 0…528 Vrms (L-L) (higher on request)

This turnkey solution for full compliance EMC emission testing according to IEC/EN 61000-3-X includes ACSControl EMC software with automatic test report generation, optional TC.FLK flicker impedance, and integration of compatible OEM power analyzers.


  • Power Range: 0…30 to 0…50+ kVA
  • Voltage Range: 0…528 Vrms (L-L)

This turnkey solution for full compliance EMC immunity testing according to IEC/EN 61000-4-X includes ACSControl EMC software and the optional TC.VSE device for fast voltage slopes and high current peaks. ACSControl provides dedicated test interfaces, waveform visualization, and automatic test report generation.

  • Power Range: 0…30 to 0…50+ kVA
  • Voltage Range: 0…528 Vrms (L-L)

This innovative anti-islanding testing solution for grid-tied power generation equipment uses TC.ACS with precise RLC load control. It offers automated test sequences and real-time analysis.


  • Power Range: 0…30 to 0…2000+ kVA
  • Voltage Range: 0…528 Vrms (L-L) (higher on request)
