Summary of IT-M3400 BIDIRECTIONAL POWER SUPPLY – WORLD’S SMALLEST PROGRAMMABLE BIDIRECTIONAL DC POWER SUPPLY
ITECH’s March 2020 IT-M3400 is an ultra-compact bidirectional DC power supply that combines DC sourcing and regenerative sinking in a 1U, ½-wide 19” rack module. Available in 0–60V, 150V, 300V, and 600V ranges and 200W/400W/800W ratings, it switches rapidly between supply and load modes with minimal overshoot and feeds absorbed energy back to the grid at about 90% efficiency. It supports stacking/parallel operation, rack mounting, and battery charge/discharge, drive cycle, life cycle, IR testing, and battery simulation via ITS5300 and BSS2000 software.
Parts used in the IT-M3400 Bidirectional DC Power Supply:
- ITECH IT-M3400 bidirectional DC power supply unit
- Rack mount kit
- Stacking/parallel connection plug-in legs
- ITS5300 software
- BSS2000 battery simulation software
- Standard charging/discharging control software
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.
SOURCING & SINKING
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.
SIMULATE AND TEST BATTERY CELLS
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.
