DC/DC Converter TEC 2WI Series, 2 Watt Compact SIP-8 package I/O-isolation voltage 1600 VDC Ultra-wide 4:1 input voltage range Fully regulated outputs Operating temperature range 40C to + 93C TEC 2WI is a new series with the design purpose to improve the prevalent 2 Watt SIP-8 DC/DC converters in terms of cost, efficiency and performance. The Continuous short circuit protection latest technology and components enable an increase in efficiency by more Remote On/Off than 20%. With the reduction of thermal loss, the operating temperature range can be expanded from -40C to +93C. The converters are fully regulated over 3-year product warranty 0 - 100% load (no minimum load is required). The models are available with ul- Designed to meet UL 62368-1 tra-wide input ranges of 4.5-18, 9-36 and 18-75 VDC. The functional I/O-isola- tion system is designed to meet IEC/EN 62368-1 with a test voltage (60 s) of 1600 VDC.
