Power Product of the Year
Product Name: IT-M3900B Regenerative Power System
Company: ITECH Electronic Co., Ltd.
Released by ITECH in December 2021, the brand-new series IT-M3900B Regenerative Power System comes with cutting-edge technology which is integrated with engineers’ innovative inspiration. It combines a bidirectional power supply and a regenerative electronic load in one. One-button-switch between source and load mode, a unique and decisive feature for the user groups that works in different applications such as battery, PV energy storage, electric vehicle, green energy and some ATE fields. This means that it can be used not only as a stand-alone power supply to provide power; but also, as an independent electronic load to sink energy and feedback remaining power to the local grid cleanly with its high efficient regenerative rate (up to 92%). IT-M3900B is a pioneering high-tech product. Meanwhile, it is also eco-friendly, helps to eliminate the heat dissipation to a minimum level and save your cost as well. IT-M3900B can fully contribute to environmental protection by reducing CO2 emissions.
Breaking through the traditional technology barriers, IT-M3600 series adopts flexible modular design, which gives it an ultra-compact body of only 1U half-rack. IT-M3900B provides CV & CC priority, helps customers effectively and flexibly solve their various tough problems in test applications request for high speed and no over-shoot power supplies. Customers can select CV or CC priority to adjust the speed of the loop circuit, to decide output with the high-speed voltage or current with no overshoot. It is applicable for high-power integrated circuit test, charging/ discharging test and the transient simulation/ characteristic test of automotive electronics.
1. The voltage can reach 10~1500V, the voltage range is wider, and both low voltage and high voltage have a range that cannot be covered by competing products
2. The maximum output current of a single unit can reach 1020A
3. High power density, compact design, 1U@6kW, 2U@12kW
4. 6K only 15kg weight
5. Fiber optic parallel technology
1) No need to calibrate after paralleling, because the optical fiber communication is purely digital, it is different from the traditional analog mode of parallel communication, and the whole machine needs to be calibrated after the parallel.
2) All the function and performance will be the same as standalone unit
3) Fiber transmission, good for anti-interference
4) Digital paralleling, fully insulated, good for protecting DUT
5) Current equalization after paralleling is better and the error is in 5%
6. High efficient power regeneration up to 92%
7. Battery simulation, built-in test interface, external professional test software
8. Built-in LV123, LV148, DIN40839, ISO-16750-2, SAEJ1113-11, LV124 and ISO21848 automotive testing standards*
9. Support CC/CV/ CW/CR in Sink mode
10. Built-in USB/CAN/LAN/digital IO interfaces, Optional GPIB/Analog&RS232

Description of the product’s purpose, unique design, innovative technology, competitive advantages
Different from other bidirectional power supplies, IT-M3900B series is a regenerative power system which combines two devices into a 1U unit. It is both a bidirectional DC power supply and also a regenerative DC electronic load. IT-M3900B not only saves space and equipment purchasing cost for you, but also enables you to connect DUT easily. ITECH IT-M3900B regenerative power system adopts compact design, redefining “high power density”, the power can reach 6kW in a 1U size, and up to 12kW in 2U size, save the cost and space.
There are 25 models included in IT-M3900B 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.
Under the current international situation, “energy saving and consumption reduction” is an issue that every company with global strategic vision must consider. The IT-M3900B series has a unique energy regenerative function that can regenerate electrical energy and then directly use it in the plant instead of consuming it in the form of heat. With the power regeneration function, IT-M3900B can feed back up to 92% power instead of consuming it as heat. It not only saves your cost of electricity, HVAC and cooling infrastructure, but also help to reduce carbon emission and impact on the environment. In addition, IT-M3900B 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.
Power transients often happen during vehicle start-up and driving. To make sure that the automotive electronic components can withstand it, it’s necessary to simulate the worst conditions during the test. IT-M3900B has built in partial voltage curves of pre-compliant standard, including LV123, LV148, DIN40839, ISO-16750-2, SAEJ1113-11, LV124 and ISO21848. Users can easily recall various waveforms directly. You don’t need to program by yourself or purchase any additional software. In addition, IT-M3900B also provides 3 professional testing software to comprehensively solve various problems encountered by customers in green energy testing and improve the competitiveness of products.
IT-M3900B series power system adopts modular design, and modules can be connected in parallel to achieve higher power. In the parallel connection, IT-M3900B series adopts ITECH parallel technology, all the function and performance will be the same as standalone unit, well guarantees that the communication between the modules is still stable after paralleling, and perfectly avoids easy interference in the communication between the modules in the traditional paralleling method. IT-M3900B series does not need to calibrate after paralleling, with digital paralleling, fully insulated, IT-M3900B is good for protecting DUT. The current equalization after paralleling is better and the error is in 5%.
