209-480V

产品型号：209-480V 产品名称：209-480V 产品分类：3-Phase Testers 品牌：Time Mark Corporation（美国时间标记公司） 产品简介：The Model 209 Line Voltage & Phase Sequence Detector can help prevent costly downtime and equipment damage by offering a quick and easy way to determine the phase sequence (ABC or CBA) and to check for missing phases in a 3-phase circuit. To use, connect the Detector to any 3-phase circuit, Wye or Delta. If all three phases are present and in the proper sequence, the ABC rotation lamp and the three line voltage lamps (A, B and C) will illuminate. An improper phase sequence will cause the CBA rotation lamp to illuminate. An open phase condition will cause both rotation lamps to flash and only illuminate two line voltage lamps. See the Condition Chart. The Model 209 is available in either a 208/240V option or a 480V option. Both models can be used in a three phase circuit with a frequency of 50Hz, 60Hz or 400Hz. 技术参数：Model Number: 209; Voltage Range: 432-528V ph-ph; Mount: Wall Switch Box 应用领域：适用于电气工程师现场测试、三相电源检测、相序验证、电压测量等工业电气测试场景 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
