2681-120VAC

产品型号：2681-120VAC 产品名称：2681-120VAC 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 2681 Voltage Band Monitor is a dual set-point voltage monitor. Input voltages between the upper and lower set-points will cause the output contacts to pull in (contacts 1 & 3 closed) and the LED indicator to illuminate. Input voltages above or below the set-points will cause the output contacts to drop out (contacts 1 & 4 closed) and extinguish the LED indicator. The Model 2681 is available in AC or DC versions. AC models of the 2681 are not frequency sensitive and can be used on systems from 50 to 400 Hz. The voltage set-points are screwdriver adjustable over a wide operating range. The SPDT output configuration is identical to the configuration of general purpose relays. This unit requires a standard 8-pin socket for mounting. 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
