Feature:1. The DC digital display current smart meter can be used for the measurement and display of a single current in the electrical circuit, and can be attached with a relay alarm output2. Can set upper and lower limit alarm, alarm delay, alarm return difference, with current realtime monitoring and alarm output function3. The ammeter has overload protection function which can better protect the circuit4. The product adopts Hall sensor which can make sure the transmission and stability of signs5. Adopted of high quality electronic components, and accuracy process, ensure for the durabilitySpecification:Item Type: Digital Display AmmeterMaterial: PlasticModel: SZD07Input Voltage: DC8-35vMeasurement Type: DC currentRange: 0.3-50ASensor: Hall sensorSensor Input Current: 25ASensor Output Voltage: 2.50.625VSampling Frequency: 2 times/sAlarm Output: Upper and lower limit alarms are output from the same relayContact Capacity: 6A/250VAC, 6A/30VBC, resistive loadWorking Environment: Non-corrosive occasions with temperature -10~50, temperature <85%RHAccuracy Level: 0.5 level .Package List:1 x Digital Display Ammeter1 x Sensor1 x English User ManualNote:1. Before powering on, please reconfirm whether the auxiliary power supply, input signal and wiring of the instrument are correct.(The corresponding value of the auxiliary power supply must match, otherwise the instrument will be burnt out)2. To monitor a single current, the transformer can not run through multiple routes at the same time, which will affect the measurement results.3. Contact capacity: 6A/250VAC, 6A/30VDC
