(1) S3-RHD-3-5553CBY

0.2%RO, 3φ3W reactive energy transducer (cross-phase )

Input nominal current: 5A; input nominal voltage: 100V;

Nominal input power 5: 866Var;

Input signal frequency: 50±5Hz;

Output range (power constant): 10000 pulses / kVarh

Output type: no voltage pure contact (optocoupler open collector output);

(2) N3-RHD-3T-5552CBY

0.5%RO,3φ3W reactive power transducer 

Input nominal current: 5A; input nominal voltage: 100V;

Nominal input power 5: 866Var;

Input signal frequency: 50±5Hz;

Output range (power constant): 1000 pulses / kVarh

Output type: no voltage pure contact (optocoupler open collector output);

Auxiliary power supply: AC220V.

Need to measure reverse power (capacitive load).


Note: 

1 system: T mark, measured by phase shift method; no T mark is measured by cross-phase method.

2 The output range (pulse number) of reactive energy transmitter is calibrated according to 1kVarh. For reactive energy measurement, when the output is negative, it means that the capacitive impedance of the system is the largest; when the positive value is output, it means that the inductive impedance of the system is the largest.

3 system select the appropriate output type see active energy notes: 2 items.

4 When measuring the forward and negative energy of the system, the power signal is output separately.

5 calibration of system power see active power note: 2 items.

6 If the user needs other special calibration, please indicate the parameter value in the contract.
