268

产品型号：268 产品名称：268 产品分类：Voltage & Frequency Monitors 品牌：Time Mark Corporation（美国时间标记公司） 产品简介：The Model 268 Over & Under Voltage Monitor is designed to ensure that the monitored operating voltage remains within a 120 VAC band. This device uses a dual op-amp comparator circuit to achieve stable and repeatable trip set-points. The output relay is energized only when the voltage being monitored remains between the upper and lower set-points. Voltages above or below the set-points will de-energize the relay, and illuminate the appropriate indicator LED. The Model 268 Over & Under Voltage Monitor is designed for continuous duty operation. 技术参数：Contacts: SPDT; Mount: 8-Pin; VF Function: Voltage Band Monitor; Voltage Range: 120VAC 应用领域：适用于电源质量监测、过压欠压保护、频率监测、发电机控制、UPS系统等电力质量监测场景 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
