AC Sources

A selection of single phase AC sources are available for rental. Adjustable output voltage, current and frequency is common throughout the range.

Modern electronic products must work under all types of input conditions, not just their ideal ones. The programmability of an AC source allows many line disturbances and non-ideal conditions to be recreated within a lab environment. By analysing devices in this way, potential design faults can be identified before mass production commences.

Common waveforms are pre-installed on selected units, with the ability to edit voltage and current. Models with adjustable frequency allow grid conditions for different countries to be simulated. This is ideal for testing products which are manufactured for foreign markets. Specific grid conditions such as brownouts or ripple control signals can be recreated.

The EAC-S has pre-installed test sequences to perform pre-compliance checks against EN 61000-4-11. These regulations define the requirements and conditions to test how power systems behave under changes to the AC mains voltage. The three standard tests are voltage dips, short interruptions and voltage variation immunity tests.

Aerospace power sources can also be accurately recreated, which commonly operate at frequencies of 400Hz and above. The EAC-S is ideal for performing these types of tests, as it has a programmable frequency range from DC up to 500Hz.
