HIGH POWER (100-350KW)MEDIUM FREQUENCY FURNACE COTROL SYSTEM

indexIMG11

Generatinon Nxt controller is the latest all digital smart medium

resonant inverter control system. The controller is built for a

AC-DC-AC type of power control providing frequency changing

from 50Hz 4-phase for resonant series converters.

 

The system has analog interace with electrical DC current sensors

and potential tranformers and an isolated monitor on the DCbus

for DCbus short circuits that occur frequently in resonant inverter

powered application due to load instabillities.

 

Generation Nxt controller is the latest all digital smart medium

frequency series resonant inverter control system.The controller

is built for a AC-DC-ACtype of power control providing frequency

changing form 50Hz 4-phase for resonant series converters.The

system has analog interface with electrical dc current sensors and

potential transformers and an isolated monitor on the DC bus for

DCbus short circuits that occur frequently in resonant inverter

powered application due to load instabilities.suitable for application

on any power levels up to 400 KW half bridge / full bridge inverter systems.

 
Models avalable for lower power without AC static switch controller.The front and

converter control chip provides high speed AC static switch control facility with high

speed interruption within 3.3 ms on 50Hz systems and soft start on dc busvwhich can

charge into a large DC bus rated capacitance without danger of over currents.A micro

-controller assisted text display system monitors all faults external to the system that

could be harmful to the equipment. the syatem is self turned and normalized for analog

feedback parameters rated for +/-10 V and so is load independent with proper CT and

PT burden calibration on the power site.

 

(This controller comes with a special three year warranty for qem users)
