1U Half Rack Mini Size

IT-M3200 provides 360W power output with 1U half rack size. Besides of the high-power density, it has high resolution, high accuracy and multi-range measurement functions. With auto-ranging design, the device covers a wide range of application requirements.

Modular Design, Flexible Combination

The unique plug-in design makes it as simple as building blocks to stack IT-M3200 devices, without purchasing any additional accessories. Meanwhile, users can choose optional IT-E154 rack mount kit to install one or more units into a standard 19-inch cabinet easily.

Multi-Level Current Range

IT-M3200 provides multi-level (Low/Middle/High/Auto) current range switching, with resolution up to 10nA, to meet the current measurement needs from Amp level to micro-amp level. The user can realize the flexible switching between low and high current measurement at the Auto level, no need to control manually. This function is suitable for testing in the fields of 5G, wearable devices and other low power consumption products.

Multi-Channel Independent Control

IT-M3200 Series is provided with independent multi-channel design to simplify the complex wiring between device and PC. When the communication interface of 1 unit IT-M3200 of a multi-channel system is connected with PC, we may realize remote control of 16 channels at maximum.

CC & CV Priority

IT-M3200 series have CC/CV priority function, which helps the user to solve the problems, and make the tests easier especially for the applications of high speed power supply or no overshooting current. Users can get fast voltage rising time by CV priority mode. This is helpful in the high-speed voltage test. Users can also choose CC priority mode to output no overshooting current. It's good for test DUT under CC working condition. This is used in various application fields such as laser test, IC test, charge and discharge test, transient simulation of power supply in automotive electronics and so on.

Soft Start/Stop Function

IT-M3200 Series can be set the rise up and fall time of output voltage or current to prevent the sudden up and down of voltage at the moment of onloading or unloading, triggering the DUT false protection action.

Foldback Protection

IT-M3200 Series with Foldback protection function, is used for turn off the output when the power supply is switched by CV/CC, so as to protect certain DUT that are sensitive to voltage overshoot and current overshoot. User can specify working mode and set the delay time protection, if the current working mode is switched, it will trigger the protection and turn off the output when the delay time is used up.

List Function

IT-M3300 does not need any software, according to users test demand, it can be edited output waveform generated by voltage and current, and can control voltage rising slope and falling slope. When receiving the trigger signal, it can switch loading waveform automatically.

Link Function

The Link function is mainly designed for the cascade control of multiple devices. It is especially suitable for the multiple DUT synchronized testing or the application of multi-channel power input. IT-M3200 series support Duplicate / On-Off / Track of three modes, user only need to set the parameters on one of the power supplies, then automatically copy the set parameters or proportionally synchronize to other devices of M3200 series in the cascade circuit. IT-M3200 series may performance two solutions of synchronous power-on and in sequence power-on When the link-on / off function is used with the on / off delay function in the menu.

Optional Accessories

IT-M3200 series provides below optional multiple interfaces on rear panel to realize different functions, like communication interface, external analog interface.
