Programmable Installation Type Digital Meter - Low Voltage Electric Components
Introduction: Programmable Digital MeterMXY Series Programmable Installation Type Digital Meter adopts SMT craft to design and manufacture in modular which realizes functional combination by the output module and the keypad.
The series meters can be used as a general digital demonstration meter and a multi-functional power meter which integrates measure, alarm, switch input and output, communications and is widely used in hydraulic, electrical power, mining enterprises and equipment manufacturing industries and various other fields.
Technical Parameters Display mode: Programmable set, shift or cycle display.
Input parameters - Programmable Digital Meter [Low Voltage Electric Components]
Rated voltage: AC 57.7V, 100V, 220V, 380V Rated current: AC 1A, 5A Frequency scope: 45~65Hz
Input network: Three-phase three-wire, three-phase four-wire
Measure accuracy: Programmable Digital Meter
Voltage, current, active power, inactive power: ±0.5% Frequency: ±0.1Hz Power factor: ±0.01PF
Active electrical energy: ±0.5%
Inactive electrical energy: ±2.0%
Start: when the rated voltage, frequency and COSφ=1.0, load working current is 0.001In, the meter can start and continuously measure the electrical energy.
Potential movement: if the rated voltage is 115％, no current in the circuit and no electrical energy accumulation or pulse output.
Output parameters: Programmable Digital Meter [Low Voltage Electric Components]
Pulse Output: collect electrode open-circuit output and collect electrode open-circuit voltage VCC≤48, current Iz≤50mA
Pulse constant: 10000imp/kWh or10000imp/kvarh. It means that: if the meter accumulation is 1kWh, the pulse output is 10000. It needs to be emphasized that the 1kWh is two energy data. In the PT, CT circumstances, the relative N pulses data corresponding to electrical energy for one time is: 1kWh ×voltage transformer ratio ×current transformer ratio.
Switch input: junction of four circuits (internally attached ＋5V power supply)
Simulation output: can provide four circuits output
Output scope: DC0-20mA/4-20mA programmable set accuracy rank: ±0.5%
Overload: 120% effective output, maximum current 24mA load: Rmax = 400Ω
Communications interface: RS485 adopts MODBUS_RTU communication regulation, Baud Rate: 1200bit/s, 2400bit/s, 4800bit/s, 9600bit/s programmable.
