1kVDC/1 second basic isolation Features Optional continuous short circuit protection DC/DC Converter UL94 V-0 package material Unregulated No heatsink required Efficiency up to 85% Converters RI Description 2 Watt The RI series has been specifically designed for applications where board space is at a premium since SIP4 these 2 Watt converters have only a slightly larger foot print than the RO series 1 Watt converters. With efficiencies up to 85%, the full output power is available over the operating temperature range -40C to +85C and the converters can be used in ambient temperatures of up to 100C with derating. The wide Sinlge Output selection of input voltage and output voltage options plus an I/O-Isolation of 1kVDC as standard makes these converters suitable for many industrial applications.
