Founded in 1971, Pacific Power Source, Inc. is an early pioneer in the development of solid-state power conversion equipment and continues to develop, manufacture and market both linear and high power PWM AC power sources.
Technically advanced, reliable and cost-effective AC power solutions with fast transient response, tight control, high peak current capability, no switching noise (linear) or very low switching noise (PWM switching) and low impedance.

Custom-made solutions for any demanding application

The LMX series; A family of high quality linear AC power supplies that excel in applications where waveform fidelity, high peak current and low output impedance are required. These units have a maximum bandwidth of 5kHz and can also be used as amplifiers. Available in manual or programmable versions, with capacities from 500VA to 30kVA.

The ASX series; A series of powerful pulse width modulating (PWM) AC power supplies. The output capacities are based on the most stringent combination of input and output voltage, power factor and temperature. The ASX series is the solution of choice when you expect high conversion efficiency even with low power factor loads. Available in manual or programmable versions, with power ratings from 1500VA to 12kVA.

AZX series; The AZX series offers fully regenerative 4-quadrant operation in AC, DC or AC+DC operating mode. Available in capacities from 30kVA to 200kVA.

AFX Series; The AFX series is a range of powerful, single-, two- and three-phase power sources and high power cabinet systems that can provide both AC and DC output. Available models range from 6kVA to 150kVA.

In addition to their standard product line, they develop custom and specialised products to help customers with specific or unique test requirements, such as DC/AC converters, power line conditioners and fully integrated ATE systems; delivering products exactly to customer specifications.

"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.”
