Home » High current AC power sources, Zenone’s GI series
Zenone power generators of the GI series are AC power sources. The series consists of models ranging from 500VA to 50kA/1000kVA for continuous or pulsed operation. Zenone AC power sources are available in single phase and three phase versions.
GI series power generators deliver a very stable alternating current at a variable frequency of 40 to 200 Hz. Up to three current ranges per unit are provided, with manual or automatic selection. Equipped with a modern and easy to use front panel interface with a large LCD display, the GI series controllers offer advanced capabilities for current test applications.
Remote control is possible via the standard isolated RS232 and RS485, or optional USB, LAN, and Fiber Optic Interfaces. Analogue inputs (Booster inputs) are also available and allow the units to be used as current amplifiers using external analogue signals. For example, they can be used as amplifiers to reproduce arbitrary current waveforms. Finally, eight digital inputs/outputs make it possible to perfectly integrate the GI series into production lines.
The GI series is ideally suited for laboratory applications (R&D), but also plays a major role in testing end products.
Specifically designed for testing circuit breakers, the GI series is equipped with a sequencer and timer, which can be used to set current and test time, and to accurately measure the switch-off time with a resolution of up to 1ms. Different modes such as ramp, drop out and loop are available to create test programmes and sequences according to standards or manufacturer’s procedures.
All these features make it possible to use the GI series in the following applications:
– Thermal and magnetic testing of switches, relays and fuses with trip time measurement.
– Heating tests of electrical contacts
– Testing of coils and transformers
– Testing and calibration of AC current measuring instruments

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
