IT-M3400 bidirectional power supply --- world smallest programmable bidirectional DC power supply

August 19, 2020 ITECH Electronics

Released by ITECH in March 2020, the brand new series IT-M3400 Bidirectional DC Power Supply comes with cutting-edge technology which is integrated with engineers’ innovative inspiration. It integrates the features of a bidirectional power supply and a regenerative load. Meanwhile, it is also eco-friendly, helps to eliminate the heat dissipation to a minimum level and save your cost as well. IT-M3400 can fully contribute to environmental protection by reducing CO2 emissions.

The compact ITECH M series, ½ wide 19″rack module of 1U high, are available in four different voltage ranges (0-60V, 150V, 300V and 600V) at power ratings of 200W, 400W and 800W.

The full range of models supports multiple units stacking and parallel connection by easy design "legs" plug-in. Fit with rack mount kit to achieve the perfect use.


The most important feature of the ITECH IT-M3400 Ultra Compact Bi-directional DC power supplies is the integration of the functionality of a bi-directional power supply and a regenerative electronic load. The unit automatically switches between power supply and load at lightning speed according to the circumstances, without overshooting current and voltage. Its regenerative character also makes the IT-3400 an enormously efficient power supply. The absorbed DC power is converted to AC and fed back into the grid with an efficiency of 90%. As a result, considerable savings can be made on air conditioning and electricity costs.


With the standard software it is possible to easily charge and discharge the battery. With the extensive ITS5300 software you can also perform extensive drive cycle testing, life cycle testing, IR testing etc. In cooperation with the extensive BSS2000 battery simulation software, the IT-M3400 power supply is ideal for simulating battery modules. Specific properties of the battery can be programmed and thus the electronics around the battery can be tested. The specific battery conditions are then very easy to simulate.


Thanks to the ability to connect different IT-M3400 power supplies in parallel, a wide power range can be covered. Also, up to 16 channels can be controlled independently or synchronously with a single interface. The compact design makes the IT-M3400 an excellent candidate for installation in automatic test systems to perform multi-channel tests. Ideal for large-scale testing of power electronics such as IGBT Power Modules or bi-directional DC/DC converters commonly used in electric vehicles. The IT-M3400 series is available with common I/O interfaces and compatible with most communication protocols.

Besides, IT-M family includes IT-M3100 Ultra-compact Wide Range DC Power Supply, IT-M3200 High Precision Programmable DC Power Supply, IT-M3300 Regenerative DC Electronic Load, IT-M3600 Regenerative Power System, IT-M7700 Programmable AC Power Supply.
