1kVDC and 3kVDC Isolation Options
Approved for Medical Applications
Suitable for Automated Assembly
High Power Density
Optional Continuous Short Circuit Protection
Efficiency to 8 5 %
ECONOLINE
DC/DC-Converter
Compared to standard 2 Watt packages, space savings of 80% and 77% respectively are achieved by these RTS & RTD
2 Watts SMD-Miniature DC/DC Converters. They have been specifically designed for applications where board space is
at a premium since these 2 Watt converters have only a slightly larger foot print than conventional 1 Watt converters.
With efficiencies up to 85%, external cooling is not needed, as the full output power is available over the operating
temperature range -40°C to +85°C. All converters have an I/O-Isolation of 1kVDC, or optionally 3kV, making them
suitable for many industrial and medical applications.
