IT-M3300 Regenerative DC Electronic Load
IT-M3300 regenerative DC electronic load can not only simulate various load characteristics, but also can feed back electrical energy to the local grid instead of heat. With high power density design, it can provide up to 800W power absorption with tiny body of only 1U half-rack. Its flexible modular architecture design can meet the test requirement of customers with different current and power. At the same time, it has high-precision output and measurement, and has made a number of safety designs for the test. It is suitable for test applications such as various types of battery discharge, multi-channel power supply, and semiconductor aging.

Functions and Advantages

1U half rack, mini size

IT-M3300 has mini size of 1U half rack and is able to output 800W. It has not only the high density but also the high resolution, accuracy, stability and etc. The output voltage can reach 600V and the output current can reach 30A. There’re 12 models for IT-M3300 series, with design of wide range output, with one unit,
it can cover a wide range of application requirements.

Module design, flexible combination

IT-M3300, with module design, without additional spare parts, it can be stacked as easy as the toy bricks. With IT-E154 rack installation kit, users can easily install one or multiple instruments into a standard 19-inch cabinet.


High energy recovery efficiency

IT-M3300 has energy recovery function, which can feedback power back to local AC grid. The regeneration efficiency can be up to 90%, which greatly reduces the user's electricity cost. It also avoids the using of cooling systems and reduces noise.

Electricity accumulation, high energy saving effect
IT-M3300 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.
The IT-M3300 is equipped with temperature measurement function as standard. With an optional temperature sensor, you can also directly view the external measurement temperature.


Multi-channel independent control, maximum 256 channels

IT-M3300 series is provided with independent multi-channel design.The channel sequence will be displayed when it combines to be a multi-channel electronic load system. The user can control each unit independently by GUI software when connecting the communication interface of one unit with PC. Each channel can be operated separately.
IT-M3300 series supports maximum 16*16 channels. One 37U rack contains 64 channels. The user may test DUT with different power ranges by parallel connection, making tests more flexible and device usage more efficient.




Battery simulation

Battery charger will monitor the voltage of battery after battery charger is connected to battery, If the connection is correctly, the battery charger comes into charge state. In Battery Sim mode, users can set analog voltage of battery, and can output low current, to simulate battery state. It can satify working demand of battery charger, which can be applied to discharging test of battery charger.

Multiple operation mode

IT-M3300 provides CC/CV/CP/CR four basic operation mode.


IT-M3300 also provides CC+CR/CV+CR/CV+CC/CC+CV+CP+CR four combined operation mode, which can be applied to the test requirements of various occasions.


Battery discharge test

The battery discharge function of IT-M3300 allows you to proceed the discharge test of battery under CC mode.3 cut off conditions can be set, including voltage, capacity and discharge time. When any of the three conditions are met, it will automatically stop the test. The battery voltage, discharge time and discharged capacity can be monitored during the test.
