CHARACTERISTIC
FEATURES
The PNO-340/1000 type flame-proof voltage converter
with return to network is assigned for infinitely variable
control of rotational speed of the asynchronous motors
driving different mining machines. The converter is
equipped with active rectifier which enables a returning of the power to network. The converter is adjusted
to work in two control modes:
Local – using intrinsically safe control keyboard,
Remote – using the mining automatics by means of:
o Intrinsically safe contact inlets,
o Intrinsically safe frequency analog inlet,
o Intrinsically safe serial transmission,
o Intrinsically safe current loop standard transmission.
The main display enables the converter diagnostics
and informs about current working conditions and activation of protections. Basic working parameters during
operating are shown on the display. The converter is
adjusted to a team-work of several converters in the
Master-Slave system realizing the moments balancing
functions.
