产品介绍
输出浮地电压:输出端子对机箱地间电压悬;浮可预置输出电压电流:可对输出电压电流作事先预置,以免因过压过流造成不必要的损坏,预置时电压不输出,按output键后电压输出;电压电流连续可调:电压电流从0至额定值之间连续可调;LED数码显示:电压电流系3位LED数码显示,电压显示分辨率为0.1V;电流分辨率为0.01A恒压恒流功能:当输出超出设置值时,电源将其自动限制,使之恒定在设置值之内,恒压时显示CV,恒流时显示cc,且CV,Cc会根据设置值实现自动转换;过载、短路保护:过载时,输出自动限制在设置值之内;短路时,输出立即中断,以保护电源不至于损坏;输入电压:AC220V±10%50Hz:外形尺寸:155x130x270(mm)。
