ITECH introduces IT-M3900 and redefines a 1U power supply!

Includes four series of power supplies and E-load

Features and Applications of the IT-M3900C series of Bidirectional Programmable DC Power Supplies

Wide range output

There are 25 models included in IT-M3900C series. The output voltage ranges from 10V to 1500V and the maximum output current of a single unit can reach 1020A. The wide-range output design provides more voltage and current combinations than conventional fixed-range output DC power supplies, which is more flexible. Just a single unit can cover a wide range of applications which makes it easy to build power systems and largely save room for you at the same time.

Power Regenerative and eco-friendly

With the power regeneration function, IT-M3900C can feed back up to 95% power instead of consuming it as heat. It not only save your cost of electricity, HVAC and cooling infrastructure, but also help to reduce carbon emission and impact on the environment. In addition, IT-M3900C has the function of automatic grid detection, which can detect phase voltage and frequency in real time and synchronizes with the grid to make energy regeneration automatic and safe.

Bidirectional current, seamless switching

The IT-M3900C series integrates bidirectional power supply and regenerative load functional characteristics in one unit for continuous supply and absorption of current. It not only can realize the function of power source, but also capable of sink to load current, that realize the fast and continuous seamless switching between output and sink current , to effectively avoid voltage or current overshoot. Compared with the conventional power supply and load test solutions, it not only saves the purchase cost, but also saves space and greatly simplifies the connection operation of the devices.

Application: Microgrid Testing

Microgrid can be regarded as a tiny power system, and also a typical distributed power generation function system. Therefore, whether they are equipment manufacturers or professional power grid research laboratories, it is all necessary to establish simulation test requirements.

  • As a photovoltaic simulation source, IT-M3900C can accurately simulate the I-V curve of the solar cell array and solar panels to supply power for the inverter to test the photovoltaic inverter.
  • As a battery simulator, IT-M3900C not only can simulate the battery to power up the inverter, but also meets the testing requirements of energy storage converters (PCS), various energy storage devices, and OBC/BOBC.
  • IT-M3900C also has a built-in voltage curve for standard automotive power grids, including LV123/LV148 and other new energy vehicle regulations testing, which can be applied to many automotive electrical characteristics testing without the additional purchase of software.

Battery simulation function

IT-M3900C series due to its unique bidirectional design and variable output impedance, the voltage, capacity, internal resistance and SOC of the battery can be set quickly through the panel to define the
battery model to simulate the charging and discharging characteristics of the battery and assist in other various test. Meanwhile, users can also choose optional ITECH professional BSS2000 battery simulation software to set the common parameters of the battery pack to quickly establish the battery characteristic curve and the initial capacity of the battery, so as to verify the characteristics of the product in different battery states. The characteristics of the state. At the same time, B S S 2 0 0 0 supports users to import
matlab battery modules or import the actual battery charge and discharge curve through csv file to make it more realistic.

Solar array simulation

IT-M3900C has a built-in maximum power point tracking (MPPT) mechanism to provide solar photovoltaic curve simulation function for maximum power point tracking test of photovoltaic arrays/modules/batteries. Users can also choose optional SAS1000 solar array simulation software, which can accurately simulate the IV curve of the solar array. The built-in SAS models of EN50530, Sandia, NB/T32004, CGC/GF004, CGC/GF035 enable to simulate the IV curve output and generate reports after simply set the parameters to test the static and dynamic maximum power tracking performance of the photovoltaic inverter. User can also edit any IV curve that shields up to 4096 points to achieve dynamic cloud shielding effect, or store 100 IV curves under different illumination and temperature in the memory, and set the execution time and order of each curve, thereby To test the long-term maximum power tracking performance of photovoltaic inverters under different climatic conditions.

Built-in a variety of standard automotive test curves

Automotive electronics may often encounter power transients during vehicle start-up and operation. To ensure that the device under test can withstand these actual transients, the tester must simulate worst-case power transient conditions during the test. According to the relevant standards of the industry, IT-M3900C had not only built-in standard automotive voltage curve DIN40839, ISO-16750-2, SAEJ1113-11, LV124 and ISO21848, but also built-in LV123, LV148 and other standards for new energy vehicles testing. Users can directly retrieve from the panel to test the performance of relevant automotive electronics, without reprogramming or purchasing additional test software, saving effort and money compared to other competitive products.
