120 Amp current Calibrator (3000Amp with coil)

The M151 Current calibrator from Meatest is accurate current source up to 120 Amp (AC and DC). The basic accuracy is 0.035% and the maximum frequency is 1000Hz.It can be used for calibration of ammeters or as stable current source for precise measurement. The M151 can also work in a simulated amplifier mode to increase current ranges of any multifunction calibrator. It is suitable for power meter’s calibration because M151 can be synchronized with the input signal not only in amplitude but also in frequency and phase.
The current terminals are isolated up to 450 Vpk against case (protective earth).The calibrator includes many other features which facilitate easy use. The concept of calibrator control and indication of its status, is based on large TFT color display, which provides all necessary information.

The calibrator is controlled by opening menus on the display and selection from menus. Frequently used functions are assigned too direct-control keys.
Calibration and testing procedures can be displayed on the screen as well as the uncertainty of the output current. The calibrator comes standard with IEEE488 bus and RS-232 serial line, which allow the calibrator to be controlled from a PC.

The M151 is supported in the automated calibration system Caliber from Meatest which is easy to use software for calibrating DMM’s.   As an option the M151-25 current coil is available which is a 25-turn coil giving you the possibility to calibrate current clamps up to 3000 Amps.

"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.”
