1.Automatic Test DC Power Supply Product Introduction

Automatic Test DC Power Supply is a DC power supply dedicated to EL tester. It can be powered on with multiple components in series more safely and quickly.Automatic Test DC Power Supply is developed by our company based on the reverse power-on characteristics of photovoltaic power plant strings.It converts alternating current into direct current and inputs it into the panel to stimulate electroluminescence, thereby testing the internal defects of EL.

FT-150010 is a research and development program-controlled power supply that controls the electrical performance and safeguard measures of Automatic Test DC Power Supply through the program software system.Its pro version is configured with high-quality software, using higher-quality imported electronic components and an open programming host to better ensure the stability and safety of string detection.
