EX2644R

产品型号：EX2644R 产品名称：EX2644R 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 2644 3-Phase Monitor continuously monitors 3-phase Wye or Delta systems for abnormal conditions. The solid-state electronic sensing circuitry drives an internal DPDT relay, allowing the Model 2644 to operate two motor control circuits, or a control circuit and an alarm circuit. An adjustable trip delay reduces or eliminates nuisance tripping caused by momentary voltage fluctuations on motor start-up. An optional restart delay gives approximately a 3.5-minute delay when the relay drops out, to allow compressor head pressures to bleed off, in the event of short-term power failures. Voltage adjustment ranges are sufficiently wide to allow for proper calibration to existing conditions. Both TRIP and NORM indicators are provided to aid in adjustment and system troubleshooting. Automatic and manual reset versions are available. The Model 2644 Monitor is not sensitive to line current, and can be used with any size motor or compressor. 技术参数：Automatic Reset: No; Certifications: CSA and UL; Contacts: DPDT; Manual Reset: No; Mount: Surface Mount; Phase Sensing: Phase Reversal,Phase Loss; Trip Delay: Yes; Trip Restart: Fixed; Voltage Sensing: Under 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
