Measurement and Local Display: True RMS Volts for two independent channels displayed simultaneously.Voltage Inputs: Two inputs, transformer isolated. Scaling is independent for each channel and is fieldselectable from built-in PT ratio library to display primary-side values when connected to PTs.UL Certification: Meets IEC Standard 1010 and is certified by Underwriters Laboratory to meet UL and CSA standards. Requires either of the two ac-only power supply options and 120V ac voltage input.Auxiliary Power: Three power supply options including a universal power supply option whichoperates from either ac or dc power source.Transducer Output Option: Two output options, either option provides two output channels, with each output representing one channel of the true RMS Voltage measurement.Mechanical: Two 4-digit, long life, red LED display, 0.56” high. Four inch round, 6.1” max. depth metal case with 4.5” Sq. Faceplate.Note: Specify PT ratio if want preset at factory otherwise default (1:1) will be provided.本公司供应百超表，品牌Bitronics 百抄表，型号VDAIE1。参数为：类型*其它，基本电流见明细/A，准确度0.1，等级见明细，参比电压见明细/V，电流倍率见明细。质量保证，欢迎咨询洽谈。
