Widely used in various instruments, electrical and mechanical equipment of
the three-phase three-wire or three-phase four-wire voltage or three-phase current
measurement parameters And show that it is all kinds of pointer meter replacements.
First, the technical parameters
Operating voltage: AC220V ± 10%
Basic error: ≤ ± 0.5F · S +1 words
Voltage meter (including the combination of the table) can be directly measured 0 ~ 500V,
the voltage transformer can be extended by 0 ~ 9999kV
Ammeter (including the combination of the table) can be directly measured 0 ~ 5A of current,
the current transformer can be extended 0 ~ 9999kA
Off the assembly line to increase the alarm control, ST485 communications, transmission output
Environmental requirements of temperature and relative humidity were -5 °C ~ +40 °C and ≤ 85% RH
