The VXS series for fast servo amplifiers…

The continuous charging/discharging of intermediate circuit capacitors in motor drives can lead to premature capacitor failure. For example, elcaps used in cutting and pressing machine applications – where acceleration and breaking operations occur by the millions – are exposed to severe stresses. Fortunately, the new VXS series turns a cold shoulder to this problem, as innovative manufacturing steps to connect the leads to the film, a specially adapted electrolyte and the use of an in-house developed anode technology enable entirely new specifications. Thus, for the very first time in an elcap, the VXS series comes with a charge/discharge endurance rating in addition to the standard specification of voltage, temperature range and current capacity. RUBYCON guarantees 100 million cycles for a voltage swing of 150V, though frequency specifications vary according to the dimensions of the specific version.

In addition to this unique characteristic, the VXS offers a load life of 5000h at 105°C, as well as high current capacity.

VXS Series Overview:
- Rated voltage range :  315V - 450V
- Capacitance :   82µF - 1000µF
- Rated current :   up to 2.92A (1000uF/315V/35mmx50mm)
- Dimensions :   22mm x 25mm - 35mm x 50mm
- Temperature range :  -25°C to +105°C
- Load life (guaranteed) :  5,000h at 105°C and full ripple current

100 million charge/discharge cycles guaranteed at a voltage swing of 150V!

The 30mm and 35mm-diameter versions offer the option of contacting the films with two tabs each to enable a higher ripple current capacity.

And for the VXS, too, RUBYCON offers customized versions that optimally meet the requirements of your application.
