The Itech IT8900A/E series high performance DC Loads


The new generation Itech IT8900A/E series high performance DC Loads has been launched by Itech in June. This series for power ratings from 2 kW to 54 kW has a high power density: 6 kW at 4U height. By means of master-slave parallel connection, electrical power can be loaded up to 384 kW. The IT8900A/E series DC loads work for currents up to 2400 A and are available in the voltage ranges 150 V, 600 V and 1200 V.

Applications and Functions

The new generation IT8900E series high performance DC Loads features standard CC, CR, CP and CV operation. In addition, the IT8900A series also features the combined CC+CV mode. This solves the problem of short peak currents when testing, for example, charging stations. CV+CR setting makes it possible to simulate the ripple when testing LED drivers. This makes it possible to improve the speed and stability of the control loop, also with PWM dimming. Furthermore, the IT8900A series offers CR+CC and CP+CC mode. This allows a wide range of tests to be performed.

Both versions, both the E and A version, can be controlled with analog input by PLC or signal generator. For automated test environments this is almost essential and works very directly. The speed of the control loop is adjustable in CV operation. This allows the load to be properly adjusted to the power supply to be tested and prevents interference. In parallel operation of several units, CC/CV mode remains available. There are functions for battery testing, automatic testing and short-circuit testing.

These high power loads are designed for various tests in industry, defence, aerospace and aerospace such as charging stations, discharge of (car) batteries, server power supplies, telecommunication power supplies, energy storage systems, fuses, relays, generators, inverters including solar and wind energy and UPS.

Control and protection

The control can be analog, but also via the front panel or via a host computer. The host can be connected via RS232, USB, GPIB, CAN and LAN. For the new generation Itech IT8900A/E series high performance DC Loads there are also several software tools available, as well as the Labview drivers.
The IT8900A/E has extensive OVP, OCP, OPP, OTP anti-reverse, current limit and power limit protections and may be overloaded for a short time.

"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.”
