2.DESCRIPTION

Model:  

S3-FD : Accuracy:0.2%RO

N3-FD:  Accuracy:0.5%RO

S3-FD transducer to measure power frequency and provide a DC output directly proportional to the change of input within  the  specified span. The input signal is shapped  to  square  wave  by  the  wave shappers circuit. The duty cycle of the square wave is change with the frequency of the input signal. Then the square wave is fed into an integrated circuit and the produced  DC output  is  proportional  to  the input frequency.

2. Example of model and parameter filling:

 (1) S3-FD-451A4NN

 0.2 frequency transducer

Input frequency range: 45~55Hz;

Input nominal voltage: 110V ± 20%;

Output range: 4~12~20mA;

Corresponding to 45Hz~50Hz~55Hz;

No auxiliary power is required;

No dual output is required.

 

 

(2) N3-FD-006V2NN

0.5 frequency transducer

Input frequency range: 48Hz~50Hz~52Hz;

Input nominal voltage: 57.7V ± 20%;

Output range: 0~2.5~5V;

Corresponding to 48Hz~50Hz~52Hz;

No auxiliary power is required;

No dual output is required.

 

 

(3) N3-FD-456V2A70Y

 0.5 frequency transducer

Input frequency range: 45Hz~55Hz;

Input nominal voltage: 57.7V ± 20%;

Output range:

I road 0~2.5~5V; corresponding to 45Hz~50Hz~55Hz;

II road -1~0~1mA; corresponding to 45Hz~50Hz~55Hz;

Auxiliary power supply; AC220V

Two outputs are required.

 

 

 Note:

 1.Because the input load of the whole transducer is small, the auxiliary power supply is not needed, and the input voltage to be measured is directly used, and at the same time, it is used as a power supply source, thereby identifying no input signal and normal input signal.

2. frequency transducers that do not require auxiliary power, the signal input range can only be: 110V ± 10% or 220V ± 10%
