产品型号：EX246 产品名称：EX246 产品分类：3-Phase Monitors 品牌：Time Mark Corporation（美国时间标记公司） 产品简介：The Model 246 3-Phase Monitor is designed to continuously monitor 3-phase power lines for abnormal conditions. This device features solid-state voltage and phase angle sensing circuits, which drive a SPDT electromechanical relay. A neutral is not required, allowing the Model 246 to be used with either Wye or Delta systems. Three versions of the Model 246 cover the 120 and 208/240 VAC, 60Hz and the 380 VAC, 50Hz ranges. In addition, the models A246 and B246 are now CSA Certified. Each option on the Model 246 monitor is adjustable throughout its operating range. The adjustment pots and LED indicators of OVER VOLTAGE and UNDER VOLTAGE are mounted on the front of the unit, for easy access. 技术参数：Automatic Reset: Yes; Contacts: SPDT; Manual Reset: No; Mount: 8-Pin; Phase Sensing: Phase Reversal,Phase Loss; Trip Delay: No; Trip Restart: No; Voltage Sensing: Under Voltage Protection, Over Voltage Protection; Voltage Range: 380VAC 应用领域：广泛应用于工业自动化、电机保护、配电系统、HVAC系统、水泵控制等三相电力监测场景 产品特点：美国原装进口，品质可靠；DIN导轨安装，方便集成；LED状态指示，直观易读；宽电压范围，适应性强；工业级设计，经久耐用
