Error of Percent table: 1.5%
Operation range:
Current:
(1%－149%)In (In =5A)
(5%－149%)In (In =1A)
Voltage:
(5%－149%) Un (Un =100V, 150V, 100V/√3)
(5%－149%)Un (Un =100V/3)
Working load:
Current: TO/TX <0.12Ω, cosΦ=1
Voltage: a/x <0.25VA (100V)
Polarity instruction
When the current or voltage is at 5% of rated, error is over 180%, it will indicate polarity status.
Note: If the current is above 10% of rated current/voltage, but there is no polarity instruction, it means there is fault, please do not increase current or voltage.
Otherwise, the instrument will burn out.
Ratio instruction
When the current or voltage is above 5% of rated, error is over 30% and less than 180%, it will indicate ratio mistake.
Insulation and withstand voltage instruction:
Terminal TX and Ground terminal () is short circuit
The shell can withstand 1.5kV/1min voltage.
Power consumption: <25VA
Harmonic suppression ratio: >40db
Dimension: 260*350*150mm
