Product Introduction:
DT1941-9X4 Three Phase Digital Display Ammeter
Three phase digital display ammeter is divided into single-phase digital display ammeter and three-phase digital display ammeter, this meter has the functions of transmission, LED(or LCD) display and digital interface, through the AC sampling of each parameters in the power grid, the measurement results are displayed in digital form.Data processing by CPU. The three-phase (or single-phase) current, voltage, power, power factor, frequency and other electrical parameters are directly displayed by the LED(or liquid crystal), while the output of 0~5V, 0-20mA or 4-20mA corresponding analog electricity, connected with the remote device RTU; And with RS-232 or 485 interface, and microcomputer for data exchange; The function instrument with setting display rate, multi-channel transmission and displaying various electrical parameters can also be called multi-function power instrument.
Scope of application:
Control system, energy management system, substation automation, distribution network automation, building automation, industrial automation, residential power monitoring, intelligent building, switchgear, etc.
Three phase digital display ammeter use method:
Without a series of resistors, directly into the loop can be, but be sure to estimate the maximum value of the measured current, usually the measurement range of our commonly used table is not large, the maximum is about 20A, can not be measured for a long time to avoid damage. Under normal circumstances, the measurement current can be used to clamp ammeter (commonly known as clamp meter).
Technical parameter of Three phase digital display ammeter:
The accuracy level voltage and ammeter is 0.5 and 0.2. The frequency table is 0.1 level; Power, power factor meter for 0.5 level display mode three and a half LED display or four display input Nominal input current AC1A, AC5A, AC10A, AC500mA, DC5A, DC20mA and other voltage voltage AC100V, AC220V, AC380V, DC100V, DC200V, DC380 V, DC75mV and other overload duration :1.2 times instantaneous: voltage 2 times (10 seconds), current 10 times (5 seconds) Frequency 50/60Hz±10% Power auxiliary power supply Switching power supply :AC, DC80~270V, linear power supply :AC220V±5% power consumption < 3VA Insulation strength AC2kV insulation resistance ≥100MΩ Average trouble-free working time ≥50000h Working conditions Ambient temperature :-10~55 ° C, relative humidity ≤93%, non-corrosive gas site, altitude ≤2500m.
