15-240

产品型号：15-240 产品名称：15-240 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 Time Mark Model 15 was designed to protect your valuable equipment from the damaging effects of phase reversal by sensing and automatically correcting for phase reversal. Under normal power conditions, incoming A B C voltage is passed straight through the device to the A B C output terminals (4 amps @ 480 VAC resistive max). If the unit detects an incoming reverse phase condition (C B A), it will light the reverse phase LED and internally switch 2 of the phases and then pass the corrected phasing out to output terminals A B C. If your load is higher than 4 amps @ 480VAC resistive, the Model 15 provides an auxiliary output relay to put in the control circuit of a remote reversing contactor. If phasing is correct, the relay will remain in the static condition (N.C contact will remain closed and N.O. will remain open). If the Model 15 detects a reverse phase input, the auxiliary output relay will energize and the relay contacts will switch (N.C contact will open and N.O. will close). 技术参数：Automatic Reset: Yes; Contacts: 3PST or SPDT (AUX); Manual Reset: No; Mount: Surface Mount; Phase Sensing: Phase Reversal; Trip Delay: No; Trip Restart: No; Voltage Range: 240VAC 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
