voltage meters

GENERAL Adopting A.C. Sampling this series meters can measure electir-cal parameters of the net such as current,voltage,power,power factoretc.And set ratio through key on panel. It contains RS-485 communication interface,adopts Modbus protocol.It is designed to transform electrical parameters signal into standard DC analog signal output,or alarm output with 2 relays. technical data Technical parametersValureNormal valueNormal valueVoitage:100V200V380V, Current:1A5A or ordered by customerOverloadCurrent:continual 1.2 times,instantaneous 10 times/1s; Voltage:continual 1.2 times,instantaneous 2 times/1sFrequency4565Hz or DCAccuracy class0.5OutputTransmit4-20mA0-20mA0-5V and so onCommunicationRS485 Modnus Protocol, 1 Start bit, 8 Data bit, 1 Stop bit, 2400/4800/9600bpsAlarm2-way passive relay; 1A/30V DC, 1A/220V AC; high,low,rising edge,falling edge mode,hysteresis coefficient can be set any valueDisplayLED display, range in -99999999, ratio can be set any value,alarm displayPower supplyVoltage rangeACDC100270VPower consumption5VAInsulation resistance≥100MΩIsolation voltage2KV/1min AC RMSMTBF≥50000hEnvironmentTemperatureWork:-10+55,Storage:-25+70Humidity≤93%RH In the place without dew and corrosive gasAltiude≥2000m
