Wide Range Programmable DC Power Supply Tonghui TH69500-20

Introduction

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

The TH6900 series supports the sequence test function, allowing users to set a series of voltage, current, and power, and automatically output according to the set rules, which better meets users’ applications such as automatic testing and aging testing. The instrument can store 50 sequences, each sequence contains 20 steps, and the function of each step can be set independently. There are 12 independent functions, including loop control, slope mode output and other rich control functions.

This instrument can output sine waves, rectangular waves, triangle waves, trapezoidal waves, etc. based on the set voltage, current and other parameters. 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 to facilitate users to test products. In addition, the TH6900 power supply has a solar cell array simulation function. In addition to realizing CC, CV, EN50530 and other mode outputs through the host computer software, the stand-alone machine also has a built-in model for simulating the solar cell array output curve.

This series of power supplies also has adjustable rising and falling edge speeds. Various modes (source CV, CC, CP) support setting rise and fall times, and the setting range is 0.01S~999.99S.
