NOB29 Demand Value Multifuncational Electrical Meter
NOB292E series multifunctional network instrument can measure more than 50 electrical quantity parameters in the electrical systems. It has 2-channelelectric energy pulse outputs. 4-channel switching value inputs and RS485 communication outpul And it can be added 4-channel switching value outputs or 4-channel transmitting outputs.
Multifuncational Electrical Meter Technical Parameter
3-phase 3-wife. 3-phase 4-wife
Rated value AC 57.7V. 100V, 220V. or 380V Overload Consistent: 1.2times Instantaneous:2 times/30s Consumption <0.5VA(each phase) Impedance >500kΩ
Rated value AC 1Aor5A Overload Consistent: 1.2 times Instantaneous: 20times/1s Impedance < 20mΩ (each phase}
Output mode 2-channel |open-collection option coupling pulse output
On the condition of rated voltage, reference frequency and COSΩ = 1.0. when load operational current is 0.001 In, it can start and measure the electrical quantity continuously.
When exerting 115% rated voltage and no current in the current circuitry, the instrument is with no electrical quantity accumulation and pulse output. Communication
1200、 2400、 4800、 9600
4 channels Output mode 0-20mA、4-20mA programmable
4 channels Output mode Normally open relay contact output
AC 240V/1A Switching value input 4-channel passive dry contact input mode Display mode LED display
