DC/DV Transducer (HTE-DV)

Product Description

1. Summary:
HTE series DC/DV transducers adopts the last HP component-HCNR200/201 linearity photocoupler. It can convert measured signal into a total separated linear voltage by HCNR200/201 and output. It adopts CAD technology, having the characters of simple theory, compact circuit, high stability and convenient installation.
HTE series DC/DV transducers has good capacity and the price is low. It can be applied widely in the fields of telecom, electric power and so on, especially in industrial process controlling.

2. Theory:
The core component-HCNR200/201 photocoupler in the circuit is made up of a LED and two optical diodes. Input optical diode can control LED ' s lighting intension and make LED stable, which almost avoids LED ' s non-linearity and stability totally. Output optical diode produces a photocurrent, which is the linearity ratio as LED ' s optical. Two optical diodes ensure the good linearity and stability of the photocoulper.
