Measurement and Local Display: True RMS Volts and True RMS Amperes displayed simultaneously.Current Inputs: One input, transformer isolated. Scaling is field selectable from built-in CT ratio library to display primary-side values when connected to CT.Voltage Inputs: One input, transformer isolated. Scaling is field selectable from built-in PT ratio library to display primary-side values when connected to PT.UL Certification: Meets IEC Standard 1010 and is certified by Underwriters Laboratory to meet UL and CSA standards. Requires either of the two ac-onlypower supply options and 120 V 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. One channel represents the True RMS Voltage and the other True RMS Amperes measurements.Mechanical: Two 4-digit, long life, red LED display, 0.56” high. Four inch round, 4.7” max. depth metal case for ac powered models. Case depth is 6.1” for VD7 auxiliary power option. 4.5” sq. faceplate.Note: Specify CT and PT ratio if want preset at factoryotherwise default (5:5 for CT and 1:1 for PT) will beprovided.本公司供应百超表，品牌Bitronics 百抄表，型号GSWIE1。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。
