EX269

产品型号：EX269 产品名称：EX269 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 269 Over and Under 3-Phase Monitor continuously monitors 3-phase lines for high voltage, low voltage, phase loss or phase reversal. This device features a solid-state voltage and phase-angle sensing circuit, which drives a SPDT output relay. The Model 269 is independent of the system load, and may be used on any horsepower motor. When phase sequence is correct, and the voltage remains between the upper and lower trip points, the output relay remains energizes. When a fault condition is sensed, the output relay drops out. The Model 269 does not require a neutral connection, and can be used on Wye or Delta systems. Each of the four voltage versions can be adjusted over a wide range. An adjustable trip delay (1-10 seconds) prevents nuisance tripping. OVER and UNDER voltage failure indicators aid in calibration and system troubleshooting. 技术参数：Automatic Reset: Yes; Certifications: CSA and UL; Contacts: SPDT; Manual Reset: No; Mount: Surface Mount; Phase Sensing: Phase Reversal,Phase Loss; Trip Delay: Yes; Trip Restart: Fixed; Voltage Sensing: Under Voltage Protection, Over Voltage Protection; Voltage Range: 380VAC,50 Hz 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
