IT-M3140
Programmable DC Power Supply

IT-M3140 Programmable DC Power Supply is specially designed for testing, production, R&D lab and ATE integration. It is only 2U half rack, but can output power up to 1850W and 3000W, and voltage output from 30V to 1200V. It has three output modes of constant voltage, constant current and constant power. Automatic wide-range output enables it to achieve a wider output voltage and current range at full power output, meeting a wider range of testing requirements and greatly saving equipment purchase costs. Not only that, IT-M3140 is a DC power supply integrating high stability, fast response (<1ms), high-level protection functions and LIST programmable functions. This series is equipped with a standard USB/LAN interface, and can be used with ITECH’s free PV3140 software to easily realize remote control and data storage, and is easy to integrate. IT-M3140 can be widely used in semiconductor device ATE, burn-in integration, testing and certification, power module and automotive electronics and other fields.

Functions and Advantages

LIST mode simulates various power supply disturbance waveforms

IT-M3140 series provides LIST programming mode. In this mode, users can generate arbitrary DC voltage disturbance waveforms, such as instantaneous voltage drop or voltage rise slowly, by setting parameters such as working steps (max100 steps), output voltage/current per step, single step duration (0.001s-3600s), rising and falling slopes, etc., to fully verify the anti-interference performance of DC loads. It is suitable for testing products such as DC-DC power modules, motor drivers, and battery-powered household appliances.

 CC/CV priority function to effectively suppress current overshoot

The IT-M3140 series has a CC/CV priority function to help users solve a variety of demanding problems in long-term test applications. By changing the CC/CV priority and loop speed settings, users can obtain voltage high speed mode or current no overshoot mode, making the test more flexible, since it is suitable for current-sensitive laser testing, and can also meet the application scenario of rapid voltage dips.

 9 protection modes to enhance test security

To further enhance the reliability and safety of product testing, the IT-M3140 series offers nine protection modes. In the traditional over / under voltage, over / under current, over power protection on the basis of the additional Fold back, Inhibit and Sense reverse connection protection function, so that not only can effectively reduce the power mode switching instantaneous overshoot, while avoiding the sense wrong connection or leakage caused by test abnormalities. With the Inhibit output ban / interlock function, making the test more secure and reliable.
