CONTROL CIRCUITS
THE MOST ADVANCED ELECTRONIC COMPONENTS

Any ideas that might improve the Performance of an already excellent Furnace technology are applied by Magnalenz. We follow the New Publications and search the most recent electronic components. Our main concern is to reach tomorrow's advanced technological level and submit to our clients only the best.

THYRISTOR CONTROLLED RECTIFIER

FER melt furnaces rectifier are not just simple diode bridge type but fully thyristor controlled.

ADVANTAGES

• At low input voltage the Furnaces can deliver power efficiently.

• Power adjustment can be done over a very large range (5%-100%).

• Line Voltage Fluctuations cause no damage.

• The current is limited during any failure or short circuit in the system which prevents bigger technical problems or expenses.

SAFETY MARGIN IN POWER SEMICONDUCTORS

FERmelt Furnaces works on parallel circuit design. Even at the highest power level the thyristors chosen work approximately at one third of the current. In other words the safety margins on the thyristor are very high. Service life of thyristors is extended due to consequent low heat losses and lower operating temperatures.

REDUCED MELTING COST WITH CONSTANT POWER

FERmelt Furnaces are designed to deliver maximum power from the beginning, which reduces the melting time, resulting in lower energy consumption.

HIGH ELECTRICAL EFFICIENCY

FERmelt Furnaces are designed to minimise electrical losses. Electrical Efficiency is 97% (Over all)

HIGH POWER FACTOR

The reactive energy used on FERmelt Furnaces is very low and the average power factor is Better than 0.95, thus no additional precautions for improving power factor are needed.

SAFETY AND PROTECTION SYSTEM

Advance parallel Inverter circuit design, result of years of experience, enable us to present one of the Safest Induction Furnaces.

PROTECTION FEATURES ARE:

• Over voltage protection at mains.
• Over current protection for Thyristor & Capacitors.
• Phase Protection at input.
• Over Voltage protection for Thyristor & Capacitors.
• On all main water cooling branches, temperature and water Flow are controlled.
• Earth Leakage detector.
• Air Temp in side panel for Protection.
