1U Half-Rack Mini size

The conventional AC power supplies are much bigger and heavier, difficult to move. The size of IT-M7700 is only ½ 1U, but its max. power is up to 600VA. Its weight is 4.5kg only. With such high-power density design, the space is better utilized. So it can be portable, convenient for bench testing and good for system building.

Multiple output modes: AC, DC, AC+DC

The output modes of IT-M7700 series include AC, DC, AC+DC. It can not only provide pure AC or DC output but also AC+DC output mode which can expand application fields and test DC offset element.


Surge / Trap Wave Function

IT-M7700 series provide surge and trap wave simulation function. User can add surge/trap wave to the output sine wave accordingly, to simulate voltage frequent fluctuation. Thus to simulate the real testing environment.


Built-in abundant waveform database

IT-M7700 series has a variety of user-defined waveforms such as square, saw and triangle.
There are 30 built-in distortion waveforms for users to edit and recall, which can also be used as the basic waveform to be recalled during list programming.

 Professional System Software
ITS5300 Test System is equipped with a battery charge/discharge testing software developed on the basis of user specifications. By editing test steps, the user may perform constant current charge, constant pressure charge and constant current/power/resistance discharge tests on multi-channel cells or battery packs. Furthermore, the software will help the user monitor cell voltage, temperature and IR, produce charge/discharge curves and monitor and store relevant data.

Real-time Charging & Discharging Monitor of Each Channel
A battery pack is typically a set of cells connected in series which exhibit different characteristics during charge and discharge. For this reason, monitoring of cells is of great importance. Apart from key parameters of each channel, ITS5300 test system may install a thermograph and IR tester to realize real-time monitoring of cell voltage, IR and temperature. During the test, user can clearly observe the test information of each channel through the software. The software has intuitive colored block charts to symbolize normality or abnormality of cell characteristics and give early warning where necessary, including channel configuration, cell voltage, current, discharge capacity and other parameters. That is not only easy for observation and record, but also improves the testing

Power-off Memory Protection
ITS5300 Test System is superior over traditional integrated charge & discharge device in that it has a power-off memory feature while the latter has single protection configuration only. Power-off memory feature is the most cutting-edge and perfect protection function developed by ITECH and designed for time-consuming aging tests. With the protection function, previously acquired data can be effectively stored intact in case of unexpected power failure or computer crash during a time-consuming aging test and the user may proceed with the test program from the faulty link after the system is back to normal. In this way, repeated tests are avoided for higher efficiency. Likewise, if the power-off state continues for long, the system will automatically cut off the active charge/discharge circuit so as to prevent overcharge and over-discharge and guarantee the safety and reliability of battery testing.

Modular design
ITS5300 Battery charge-discharge testing system is comprised of power supply, electronic load,internal resistance tester, temperature data acquisition instrument and IT9320 software. It breaks through the traditional testing system limitation,providing professional testing steps toimprove testing efficiency. User can choose the most suitable equipments for their own test requirements to build automotive test platform.
