Silcomax Large / Light — high-power industrial rectifiers up to 80 kA, up to 1200 V
Country: Italy · Model: Silcomax Large / Light
Silcomax high-current industrial rectifiers deliver up to 80 kA at voltages up to 1200 V DC in the Large version and up to 25 kA in the Light version. They are installed on DC arc furnaces, zinc and titanium electrolysis, metal electrowinning and chlor-alkali plants, where the rectifier must serve for a long time.

Description
The series is built on more than 30 years of experience in making medium- and high-power AC-to-DC converters. The Silcomax Large is a three-phase bridge rectifier with a six-pulse response for each bridge, and the high current is usually obtained by connecting two bridges in parallel. This scheme has long worked on DC arc furnaces and in non-ferrous metallurgy, where the rectifier is expected to withstand heavy duty. The Silcomax Light was developed from the experience of the larger version for the requirements of electrochemistry and electrowinning regarding failure-free operation, efficiency and redundancy. Current and electrode regulation is integrated through the ARTICS automation platform. The power supply system can be ordered fully engineered, from the software and mechanical part to rectifier calculation and commissioning.
How to choose
The main parameter is the load current. Up to 25 kA for electrolysis cells and electrowinning, the Light is enough, while a DC arc furnace or zinc electrolysis with a larger current needs the Large up to 80 kA with two parallel bridges. The 1200 V DC limit is checked against the total voltage of series-connected cells or against the arc voltage. For DC drives with smaller currents, the same catalogue has thyristor converters Answer Drives DC / ADDvantage-32 / Mentor MP at 25–4000 A and 230–1500 V DC.

FAQ
What maximum current does the Silcomax Large rectifier give?
Up to 80 kA at an output voltage up to 1200 V DC. Such a current is usually built up by two three-phase bridges connected in parallel.
How does the Silcomax Light differ from the Silcomax Large?
The Light is rated for a current up to 25 kA and was created for electrochemistry and electrowinning, where redundancy and efficiency matter. The Large gives up to 80 kA and works mainly on arc furnaces and in non-ferrous metallurgy.
What is included in the supply of a Silcomax rectifier installation?
Besides rectifiers, HV/MV transformers and switchgear, thyristor units, harmonic filters, control panels and monitoring systems are ordered, as well as supervision of installation, installation and commissioning.
Can an existing high-current line based on Silcomax be modernized?
Yes, engineers carry out the modernization of existing lines to eliminate the drift of analog systems, reduce downtime, extend equipment service life and improve MTBF and MTTR figures.
