application
Basic design
Smoothing, energy storage, or pulse opera-
tion in telecommunication demanding
power supplies, process control, AC-motor
control, traction, welding and measuring.
The ALS30/31 series of screw terminal
capacitors cover a wide range of case
sizes and voltage ratings featuring high
ripple currents and long life performance.
They are ideally suited for industrial and
commercial applications demanding high
reliability and long life expectancy such as
frequency converters, UPS systems and
switch mode power supplies.
