JEMA designs and manufactures all kind of customized static power electronics equipment, typically higher than 10 kVA: rectifiers, inverters, UPS, power converters, frequency converters 50-60-400 Hz, active filters, voltage stabilizers, high voltage power supplies, crowbars, etc.,

These systems incorporate digital control and communication equipment and are capable of adapting to very varied requirements: standards, redundancy, special programming, signalling, protections, antiseismic protection, tropicalization, etc.

JEMA structures its activities in four product lines, in order to be able to fit our efforts to each sector characteristics and needs:

• Secure Power: oriented to critical installations that needs a continuous, reliable and high quality power supply, both DC and AC (control rooms, turbines, cooling systems, security and fire systems, etc.)
  
  
• Custom Power Supplies: unique systems for large research nuclear fusion or particles accelerators experimental facilities. This market is characterized by its exclusivity and high requirement, taking into account that we have to develop solutions that face today’s technological borders.
  
  
• UPS and Converters: very robust and reliable customized units to solve specific requirements for applications from 10 a 1300 kVA (and even many MVA, in parallel), under the most diverse standards and demands, in non-commercial environments.
  
  
• Industrial Drive Systems: complex systems to motorize and control large industrial machines. In this field JEMA gathers its applications and knowledge of control and regulation systems for large industrial machines, cement furnaces, cutting lines, cold and hot rolling mills, calendars, pickling lines, wiredrawers, steel and paper reelers, static excitations, paper mills, etc.
