Description
The RI3 series has been specifically designed for applications where board space is at a premium since
these 3 Watt converters have the same foot print as the RI series 2 Watt converters. With efficiencies
up to 90%, the full output power is available over the operating temperature range -40°C to +85°C and
the converters can be used in ambient temperatures of up to 100°C with derating. The wide selection
of input voltage and output voltage options plus an I/O-Isolation of 1kVDC, 2kVDC or 3kVDC makes
these converters suitable for many industrial applications.
