Inverter Type : Sequence Inverter Characteristics ;
It is possible to provide maximum power to the pot from the beginning until the end of the melting. As it is not rectifier controlled the harmonic components are few.
Fixed dc tension required for the inverter to function smoothly.
Power factor rising to the rate of 0,98.
Fast protection system in order to protect the electronic parts of the inverter.
2 inverter thyristors with high current and 2 thyristors which are not complicated and which rarely breakdown.
Snubber elements with little loss able to resist high temperatures with aluminum body which muffles the switching in the inverter and rectifier parts and the sparks and protects the thyristors.
Transformer ensuring galvanic insulation to provide personnel safety.
Single electronic control card with reliable dsp chip control.
In addition to the rectifier control card ensuring the soft start and static control, additional protection with compact contact breaker and fast circuit breakers.

RECTIFIER CONTROL CARD WITH MICROPROCESSOR PROGRAM ;
There is a high based PIC which can do programming on the rectifier card. Program loading can be made with a PC or a laptop computer.
By doing the microprocessor program;
Ensuring the phase flow balance by igniting the rectifier thyristors at the required frequency
By changing the ignition pulse width of the rectifier thyristors making it compatible with every type of drive card or thyristors
As a result of the presence of a large number of analogue and digital inputs and outputs regarding the future technological developments to be able to make additions through the program without making any addition of any parts on the circuit.
Soft start take off feature.
The feature of perceiving the short circuit after the rectifier and preventing softening the surge current through the dc reactor and cutting off the network statically through the contact breaker thus preventing the damage to the rapid fuses.
ONE MAIN CONTROL BOARD
Control Card Characterıstıcs;
The main card microprocessor controlling the system has been programmed with a digital operator. This system is a control system used in PLC and computer technology.
All the adjustments of the system are entered through a laptop computer to the main control card.
The master card working furthermore like a PLC :
PLC (Programmable Logic Control); sistemi sürekli kontrol ve kumanda etmekten sorumludur.
PLC (Programmable Logic Control) : it is responsible for the continuous control and command of the system.
The master card receives information from the other control cards, protection and control circuits.
LCD screen provides information to the operators regarding the situation of the system at that time.
The control of the unit is an easily controllable manner.
It provides comprehensible messages about the system to the operator.
In the event of any breakdown the system stops automatically.
The failures that happen are stored in the MASTER CARD memory and a retroactive failure follow-up can be effected.
The technological developments in the future may be applied to the system.
