AC sources

Especially in times of increasing electrification, rising quality requirements and strict international standards, a precise AC power supply is essential. AC sources play a key role in ensuring standard-compliant tests and optimizing production processes.

Precise and stable output parameters

AC sources enable precise adjustment and stability of voltage and frequency, even under variable load conditions. This is crucial for test processes where any deviation could falsify the measurement result. Modern AC sources automatically compensate for interference and thus ensure reproducible results - a decisive advantage for quality control and research.

Flexible adaptation to international standards

With an AC source, mains voltages and frequencies can be simulated worldwide - ideal for companies developing products for the global market. This makes it easy to carry out tests for different country specifications. This saves space, time and investment costs.

High reliability in continuous operation

Industrial environments require devices that work reliably over long periods of time. Our AC sources are designed for 24/7 operation and have comprehensive protection mechanisms against overload, overtemperature and short circuit. This minimizes downtimes and increases operational reliability.

Efficient integration into test systems

Thanks to modern interfaces such as LAN, USB or GPIB, AC sources can be easily integrated into existing test benches. Control can be both manual and automated, allowing work processes to be optimized and test cycles to be shortened.

AC sources are used in a wide variety of applications, ranging from research laboratories to highly automated production facilities. They are used wherever electrical devices need to be tested, developed or calibrated under defined mains conditions. The following examples show typical fields of application and their special features.

Electronics testing and quality assurance

In electronics production, AC sources are used to test components, devices and systems under different mains conditions. This allows weak points to be identified at an early stage and product faults to be avoided.

Automotive and e-mobility sector

In the development of electric and hybrid vehicles, AC sources are essential for testing onboard charging systems, wiring systems and power electronics. Different grid conditions and frequencies can be simulated precisely.

Research and development

Universities, institutes and laboratories use AC sources to research new technologies, develop components and simulate complex electrical scenarios.

Energy and utilities industry

In the energy sector, AC sources are used to simulate AC grids and test feed-in systems, for example for renewable energies or emergency power systems.

Aerospace technology

Aircraft and aerospace systems must meet high standards and requirements. AC sources enable tests in accordance with international aviation standards and thus guarantee operational safety even under the most demanding conditions.

The choice of the right AC source depends on various technical and normative requirements. In addition to power and voltage range, frequency stability, interfaces and safety functions also play an important role. The following criteria will help you to find the right device for your specific application

Power and voltage range

When selecting an AC source, the required power range is crucial. Laboratory applications often require 500 VA to 3 kVA, while industrial test systems may require 30 kVA or more. The voltage range should at least cover the mains voltages of all relevant target markets.

Frequency range and stability

A wide frequency range enables testing for different markets and applications. For aviation applications, 400 Hz is mandatory, while special frequencies may be required for shipping or railway technology. Frequency stability of less than 0.01 percent ensures reproducible results.

Interfaces and control options

Communication interfaces are indispensable for automated test sequences. In addition to hardware interfaces, software solutions that enable simple integration into test software such as LabVIEW or Teststand are often also important.

Protective functions and operational safety

Safety functions such as overcurrent shutdown, overtemperature alarm, overvoltage protection and galvanic isolation not only increase the service life of the device, but also protect the equipment under test. If users work with the devices permanently in the same room, you should also pay attention to high-quality fans. These work quietly, reduce noise pollution to a minimum and provide optimum cooling for the power electronics.
