Three-phase line filter

EMC Mains Filters for Industrial Automation

In the modern industrial environment, the reliability of control electronics is constantly threatened by electromagnetic interference. The external mains filters (EMC filters) offered by Alter Elettronica are essential components for ensuring your system’s full compliance with current European regulations on electromagnetic emissions. Their primary technical function is to protect the line, minimising the conducted emissions...Continue reading

Inductors d.c.

DC Inductors for servo drives

The DC inductors designed by Alter Elettronica are magnetic components used both to improve the form factor of the motor armature current and to eliminate the dead zone around zero in bidirectional servo-converters with circulating current, such as our D-Series 6AXD axis control module. Manufactured using the highest quality magnetic materials, our inductors stand out...Continue reading

Size analog isolator 13/001

Analog Isolator 13/001 (DC Decoupler)

The 13/001 analogue isolator developed by Alter Elettronica is the definitive solution for resolving problems with ground loops and interference in automation panels. Its primary function is the galvanic isolation of DC signals, an essential requirement when safely interfacing electronic instruments, PLCs, sensors or drives from different manufacturers that share one or more line references. Without...Continue reading

Capacitor box

Capacitor Modules for Servo Drive DC-BUS

Under high current conditions in particularly demanding industrial duty cycles – characterised by sudden accelerations, decelerations or high inertial loads – the capacitors fitted inside the servo drives can overheat and become saturated rapidly. If this temperature rise persists over time, it inevitably causes the drive to shut down (alarm), resulting in sudden machine stoppages....

Three-phase chokes

Three-phase Chokes (Mains Inductors) for Drives

The three-phase reactors (often referred to as mains or line chokes) designed by Alter Elettronica are essential magnetic components for the protection and efficiency of your motion control systems. Installed upstream of servo drives, they perform a dual protective function: on the one hand, they dampen transient current peaks from the power supply, protecting the...Continue reading

Braking resistors

Braking Resistors for Inverters and Servo Drives

braking resistors are vital components for ensuring the reliability and safety of your motion control systems. When an electric motor (for example, on machine tools or axes with high masses) undergoes rapid deceleration, it acts as a generator: kinetic energy is fed back to the drive in the form of electrical energy, triggering dangerous voltage...Continue reading
