working range electricity (1%~149%)In (In =5A)
(5%~149%)In (In =1A)
voltage (5%~149%)Un (Un =100V,150V,100V/)
(5%~149%)Un (Un =100V/3)
workload electricity TO对TX<0.12Ω cosΦ=1
voltage a对x<0.25VA (100V)
Polarity error indication When the operating current (voltage) reaches more than 5% of the rated current (voltage) and the error exceeds 180%, there should be polarity indication。
Note: if it is more than 10% of the rated operating current (voltage), there is still no proper polarity indication, indicating a fault. Please do not increase the current (voltage) to avoid burning out the instrument。
Variable ratio error indication When the operating current (voltage) reaches more than 5% of the rated current (voltage) and the error exceeds 30% but is less than 180%, the error indication of variable ratio should be given。
Insulation and voltage test and instructions terminalTX()Terminal is same
The power socket can withstand the housing1.5kV,1minwithstand voltage
