INFO & CONTACT ADDRESSES
ET System electronic GmbH was founded in 1986 in the heart of the Rhine-Neckar-Triangle. As a
subsidiary of a leading electricity utility group, the company quickly took on a leading role in the
area of laboratory power electronics and associated electrical measurement. The existing
know-how in power technologies in the 90s gave rise to the “Power Solutions” product division
as a strong extension of the historical “Test & Measurement” range.
Since 1997, we have been working successfully as an independent, privately held company with
customers in all lines of business from industry, medical care, railway technology and automotive
electronics.
By means of our high vertical range of manufacture and our ever expanding development
division we can fast and flexibly adjust to our customers’ requirements. Necessary approvals
such as CSA, UL, VDE, TÜV etc. are flexibly carried out by qualified personnel. The approval
procedures are performed within the scope of development planning and thus do not negatively
impact the start of manufacturing. Permanent manufacturing control through accredited
laboratories and an ISO 9001 compliant quality management system guarantee a constant
high-level series-production quality.
We offer repairs and adjustment for units outside of our warranty period. Please contact your
local distributor for further information.

1.1 System Overview
1.1.1 Overview of EAC-4Q-KS series
The ET System EAC-4Q-KS series is a high-performance AC/DC power source, using SiC MOSFET
PWM technology, which contains multi output power levels from 15kVA to 500kVA. With an
output frequency range from DC to 2kHz (standard 1kHz, 2kHz with -HF option), standard output
300V L-N (higher voltage can be customized). KS series uses bi-directional design, which makes it
possible to be used as grid simulator to test distributed generation systems. KS Series is well
suited for aerospace applications. Remote control interfaces and SCPI command language are
provided for easy integration into ATE systems. With touch panel on the front panel, user can
control the power source with GUI software. System status indicators and emergency stop
button are also installed on the front panel. Programming interfaces including LAN and RS485
interfaces are standard, and optional RS232, analog control interfaces are available for
