½ U Mini volume

The IT-M3300 has a ½U mini size and can provide 800W power input, which not only has high power density, but also has high resolution, high accuracy and high stability, etc. The input voltage can reach 600V, and the input current can reach 30A. With an input voltage up to 600V and an input current up to 30A, there are 12 models in the series and a wide range of inputs, one machine can cover a wide range of applications.
Modular architecture, any combination
The IT-M3300's modular plug-and-play architecture allows instruments to be stacked like building blocks without the need for any additional accessories. The IT-E154 Rack Mount Kit is also available for users to easily mount one or more instruments in a standard 19-inch cabinet.

The IT-M3300 is equipped with an energy recovery function that recovers electricity with a conversion efficiency of up to 90%, which greatly reduces the user's cost of electricity, as well as avoiding the use of air-conditioning or expensive refrigeration systems and reducing noise.

IT-M3300 utilizes power electronic conversion technology to recycle and reuse 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, users can directly view the current total power back in the instrument panel.
The IT-M3300 comes standard with temperature measurement, and with the optional temperature sensor, you can also directly view the externally measured temperature.

The IT-M3300 has a flexible multi-channel design architecture that allows the user to form a multi-channel source-loaded system with multiple IT-M3600s, with each instrument interface displaying the channel number. By connecting the communication interface of one of the power supplies to the PC, each power supply in the system can be controlled independently in the upper computer software, and each channel can be operated completely independently.
IT-M3300 can reach up to 16*16 channels, 64 channels can be configured in one 37U cabinet, and through the parallel function, it can support a variety of different power to be tested, which not only makes the use of the user more flexible, but also greatly improves the utilization rate of the equipment.

In the charger charging principle, the charger monitors the battery voltage after connecting to the battery, and if the battery is connected reliably and correctly, the charger enters the charging state.The Battery Sim mode of the IT-M3300 series allows the user to set a value to simulate the battery voltage, and has a weak output capability, which can output a small current to simulate the state of the battery. The Battery Sim mode allows the user to set a value to simulate the battery voltage and has a weak output capability to output a small current to simulate the battery state.

The IT-M3300 is equipped with 4 basic operation modes, CC/CV/CP/CR.

The IT-M3300 also features four composite operation modes, including CC+CR, CV+CR, CV+CC and CC+CV+CP+CR, which can be adapted to the testing needs of a wide range of occasions.

IT-M3300 has a battery discharge function, which can be used to discharge test batteries in constant current mode. Three test shutdown conditions for batteries can be set by yourself: shutdown voltage, shutdown capacity and discharge time. When any one of the three conditions is met, the test will be automatically interrupted. Battery voltage, discharge time and discharged capacity can be observed during the test.
