Power Supplies Zoltech offers a wide selection of open-frame (U-frame and L-frame) power supplies to fit the pre-punched bottom panels of the VX-11 chassis. These supplies range from 100W to 700W with up to four DC outputs. These supplies have been selected to offer an optimal combination of small size, high efficiency, minimal heat generation, light weight and high reliability. They are shielded and filtered to allow the use of sensitive devices within the chassis. The VX-11 chassis, using these supplies, have been verified to comply with FCC class A EMI limits. All of the supplies listed in the table use switching regulator technology. Linear regulator supplies and other voltage and current combinations of switching supplies are also available.
