Description
EN-60601-1 Certified
(Suffix H3)
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 ope-
rating temperature range -40°C to +85°C. All converters have an I/O-Isolation of 1kVDC, or optionally 3kV,
making them suitable for many applications.
