YB1731B直流稳压电源/YB-1731B
YB1731B直流稳压电源产品介绍（中文）
YB1731B是一款高性能三路输出直流稳压电源，采用液晶显示屏设计，可同时显示两路可调电压/电流值。该设备具备0-30V/0-3A双路可调输出及5V/3A固定输出，采用先进的稳压稳流技术，能实现两种工作状态的自动转换。产品具有多重保护功能，包括电流限制保护（限流点可调）、过载和短路保护等。其核心优势体现在低纹波噪声（CV≤1mVrms，CC≤1mArms）和高稳定性（电源效应CV≤1×10-4+0.5mV）。两路输出支持串联/并联工作模式，在并联时可通过主电源实现电流跟踪功能。160×260×310mm的紧凑结构和9kg的重量使其适合实验室、生产线等多种场景使用。1712
YB1731B DC Regulated Power Supply (English)
The YB1731B is a triple-output DC regulated power supply featuring LCD displays for simultaneous monitoring of two adjustable voltage/current channels. It provides dual adjustable outputs (0-30V/0-3A) plus a fixed 5V/3A output, with automatic switching between voltage regulation and current limiting modes. Key technical highlights include ultra-low ripple noise (CV≤1mVrms, CC≤1mArms) and high stability (line regulation CV≤1×10-4+0.5mV). The series/parallel operation capability allows flexible voltage/current combinations, with master-slave tracking in parallel mode. Protection features include adjustable current limiting, overload and short circuit protection. With compact dimensions of 160×260×310mm and 9kg weight, this unit is suitable for laboratories, production lines and educational applications. The four-display interface (YB1731B model) provides clear parameter visualization without requiring measurement switching. 81117
