VSP Series of Programmable Power Supplies set a new standard for flexible, reliable AC to DC power systems in OEM, Industrial and Laboratory applications. These are designed with excellent thermal management and can be conveniently stacked in rack mounts without any space between them for ventilation. The zero Voltage soft-switching technique employed in them virtually eliminates the switching transients to derive lower noise, which is more closer to linear levels. This also helps increasing the overall conversion efficiency which in turn decreases the heat generation, thus reducing the stress on the power components which results in greater reliability.
