Functions and Advantages 

High power density, compact size design

ITECH has been adhering to the high power density design to help customers optimize test solutions. IT-M3800 series provide up to 6kW power in 1U chassis, and up to 12kW power in 2U chassis. ITECH entire high power density product line is more complete and comprehensive.

Wide range design, save your purchasing cost

The IT-M3800 series has 25 models, with voltage from 10V~1500V and current up to 720 A. The wide range design provides users with more voltage and current combinations than the traditional fixed range DC loads, making it more flexible. A single unit can cover a wide range of applications, significantly reducing the complexity of system building and saving room.

Power regenerative and eco-friendly

With the power regeneration function, IT-M3800 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-M3800 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.

Electricity accumulation, high energy saving effect

IT-M3800 uses power electronic conversion technology to recycle the output energy of the power supply under test under the premise of completing the test power experiment. Through the internal high-speed voltage and current sampling, the user can directly view the current total amount of feedback on the instrument panel, including voltage/frequency/power of each phase. The total power, real time and historical total recovered electricity. The IT-M3800 series can continue to accumulate electricity on the basis of the value before the last shutdown.

Battery discharge test

The IT-M3800 series have discharge test function, which is suitable for discharging tests on various portable batteries. Three test cut-off conditions of the battery can be set by yourself: cut-off voltage, cut-off capacity and discharge time. When any one of the three conditions is met, the test will be automatically interrupted. During the test, the battery voltage, discharge time and discharged capacity can be observed.

Parallel function

To be convenient and flexible, IT-M3800 uses the master/slave control mode to connect multiple e-loads in parallel to realize high-power testing requirements. Meanwhile, it adopts ITECH's optical fiber parallel technology to solve the problems of slow speed and poor accuracy in the traditional parallel mode, suitable for calibration measurement, research and development lab, production line and ATE test setup.

Multi operation modes

IT-M3800 provides four basic operating modes of CC/CV/CR/CW.
