Function:
Real- time Measurement and indication on AC or DC Voltage(Current) in an electric circuit; Programmable CT/PT ratio; Higher and lower limit alarm output and programmable rely time of alarm.
Measuring range:
AC ammeter AC 0.05-6A, external CT is necessary if more than 6A.
DC ammeter DC 0.05-6A, external electrical shunt is necessary if more than 6A.
Accuracy: ±(0.5%FS + 1 digit)
Measuring display mode:4 LED nixietube effective value display.
Resolution: last figure one digit
Overflow indication the top digit display "1" or "-1" and other digit hiding
Auxiliary power supply: AC 220V±10%
Alarm contact capacity: AC 250V/1A
Alarm Shift Difference :0.1 %FS -50.0% FS
Alarm Delay time: 0.0-99.9s Programmable
Terminal arrangement and wiring connection:
Power : Auxiliary power input port of instrument, Auxiliary power suppy is AC 220V±10%(please note if you need special power supply) .
Input: Signal input port of instrument, HI represents "+" port of DC input signal. fire wire terminal of AC voltage input signal and inlet wire terminal of AC current input signal.
LO : "-" port of DC input signal, the other one wire of AC voltage input signal;the outlet wire terminal of AC current signal input
OUT: the alarm contact output port of meter
