22-LM

产品型号：22-LM 产品名称：22-LM 产品分类：3-Phase Monitors 品牌：Time Mark Corporation（美国时间标记公司） 产品简介：A microcontroller-based universal 3-phase monitor for protecting 3-phase motors from abnormal power conditions. It can detect under voltage, over voltage, voltage unbalance, reverse phase, and single-phasing even when regenerated voltage is present. The Model 22 includes adjustable trip and restart delays to prevent nuisance tripping during power fluctuations and short cycling in compressor applications. The LED status indicators and adjustment pots for Voltage Adjustment, % Unbalance, Restart Delay and Trip Delay are mounted on the front of the unit for easy access along with 2 SPDT relay contacts. Automatic or manual restart versions are available. The Model 22 does not require a neutral connection and can be used on either Wye or Delta systems. 技术参数：Automatic Reset: No; Contacts: SPDT(2); Manual Reset: Yes; Mount: Surface Mount; Phase Sensing: Phase Reversal,Phase Loss,Phase Unbalance; Trip Delay: Yes; Trip Restart: Yes; Voltage Sensing: Under Voltage Protection, Over Voltage Protection; Voltage Range: 95-120VAC 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
