A2722

产品型号：A2722 产品名称：A2722 产品分类：Current Monitors 品牌：Time Mark Corporation（美国时间标记公司） 产品简介：The Model 2722 Current Unbalance Detector is designed to monitor 3-phase AC current (or compare three single-phase AC currents). A solid-state electronic sensing circuit drives an internal DPDT relay which energizes during normal, balanced conditions. An unbalanced condition will cause the relay to drop out. The Model 2722 accepts current inputs up to 5 amps and will consider zero amps as balanced (relay stays energized), making the device suitable for use with 3-phase heaters. The Model 2722 has adjustments for percent of unbalance and time delay before tripping. It will automatically reset upon restoration of correct current balance, or a normally-closed momentary switch can be connected for a manual reset. External CT’s can be used to extend the operating current range. 技术参数：Certifications: CSA and UL; Contacts: DPDT; Mount: Surface Mount; Trip Delay: Yes; Current Input: 5A; Voltage Range: 24VAC 应用领域：适用于电机过载保护、电流监测、负载状态检测、节能控制、设备状态监控等电流监测场景 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
