TH6402B Four-Channel Programmable Linear DC Power Supply

TH6400 series multi-output programmable DC power supply covers 5 models (single channel power range 5W-180W), of which TH6402B is 4-channel output, the rest of the models are 3-channel output. The whole series of power supplies are equipped with serial and parallel connection between channels and synchronized output function, and the output parameters of all channels are displayed on the same screen, which is more convenient and intuitive to use.

TH6400 series power supplies are all linear, program-controlled output design, so this series of power supplies with small ripple, low noise, high precision, stability and excellent performance. The whole series adopts 4.3-inch TFT LED display, different channels are displayed in separate screens and differentiated by high-contrast colors.The UI design of the instrument adopts menu-based operation, soft keys, knobs to control and input parameters, which is easy to use and well adapted to the fast operation of production lines as well as to the application needs of colleges, universities and laboratories.

TH6400 series comes standard with RS232, USB HOST and USB DEVICE interfaces (Note: TH6402A does not have RS232 and USB DEVICE interfaces), optional GPIB interface, support for SCPI and MODBUS communication protocols, and easy to purchase the host computer software or self-editing to meet the needs of system integration. Small size, standard chassis size and front and rear panels can be output design features, so that the TH6400 series power supply can be easily integrated into standard cabinets.

Functional Features

A. Multi-channel outputs

TH6400 is a full series of multi-output rectangular power supply, its voltage and current accuracy is up to 1mV and 0.1mA respectively. series, parallel and synchronized outputs are freely combined between channels. In synchronized mode, change the set value of one of the channels, the other synchronized channels will also be automatically changed proportionally.

B. Facilitating automated integration

TH6400 series power supplies are equipped with outputs on the front and rear panels, have 1/2 standard chassis size, and are equipped with a full range of communication interfaces to support SCPI and MODBUS communication protocols, making them easy to integrate into automation systems.

C. Remote compensation functions

When the output current of the instrument is large and the resistance value of the wire is large, the voltage on the wire from the output terminal of the instrument to the DUT will be larger, resulting in the actual voltage at the ends of the DUT being smaller than the output voltage of the instrument. Using the remote compensation function can compensate for the voltage drop on the test line to ensure that the voltage at the ends of the DUT is the actual output voltage set. the TH6400 series is equipped with a compensation terminal on the rear panel only, while the 6200 series, 6300 series, and 6500 series are equipped with both front and rear panels with a compensation terminal.

D. Humanizing design

The TH6400 series is equipped with a 4.3-inch TFT LCD display, where the setup parameters and output parameters of all channels are simultaneously displayed on the same screen. The left side of the screen is equipped with individual output buttons for each channel corresponding to the different channel display areas, and the total output button in the upper right corner is used for all channels to be output or turned off at the same time. Digital encoder knob and digital keyboard can input the setup parameters quickly and accurately, avoiding the inefficiency and inaccuracy caused by potentiometer adjustment.

E. Data-logging functions

TH6400 can also record the output voltage, output current and time data, the data sampling rate of about 100ms, after the end of the collection in the form of excel table saved in a USB flash disk, easy to analyze the data in the later stage. TH6402B does not support the data logging function for the time being.
