Brief Introduction

TH6900 series is a programmable switching DC power supply with a wide range of output. There are 21 models of 750W, 1500W and 3000W available. The instrument supports up to 10 master-slave units of the same model in parallel to meet higher output current and output power requirements.

TH6900 series supports sequence test function, allowing users to set a series of voltage, current, power, and automatically output according to the set rules, to better meet the user's application of automatic test and burn-in test. The instrument can store 50 sequences, each sequence contains 22 steps, the function of each step can be set independently, a total of 12 independent functions, including loop control, slope mode output and other rich control functions.

This instrument can output sine wave, square wave, triangle wave, trapezoidal wave, etc. according to the set parameters such as voltage and current. Based on these waveforms, users can form a sequence output. The sequence can be set up to ten steps, and each step can be set to any A waveform and the duration of the waveform, which is convenient for users to test products. In addition, the TH6900 power supply has a solar cell array simulation function. In addition to CC, CV, EN50530 and other modes output through the host computer software, the single machine also has a built-in model for simulating the output curve of the solar cell array.

This series of power supplies also have adjustable rising and falling edge speeds. In all modes (source CV, CC, CP), the rise and fall time can be set, and the setting range is 0.01S~999.99S.
