DESCRIPTION
The SAT2815D is a 15W, Dual, low cost DC-DC converter designed for high reliability,
low power instrumentation applications. It is packaged in a high-grade plastic modular
package that is conformally coated and potted internally for improved reliability in high-
stress environments. The SAT2815D will perform at high efficiency (up to 85% at 15W)
over the full temperature range of -40
o
C to +105
o
C. There are 2 configurations
available: 650V & 6KV isolated. These units are designed for high reliability in
commercial, industrial and military applications such as Industrial motor controls, radar
base stations, and missile power supplies.
