DC/DC Converter TEC 3WI Series, 3 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 + 90C TEC 3WI is a new series with the design purpose to improve the prevalent 3 Watt SIP-8 DC/DC converters in terms of cost, efficiency and performance. The Continuous short circuit protection latest technology and components effectuate a high efficiency for a low thermal Remote On/Off loss. This enables an operating temperature range from -40C up to +90C. The converters are fully regulated over 0 - 100% load (no minimum load is re- 3-year product warranty quired). The models are available with ultra-wide input ranges of 4.5-18, 9-36 Designed to meet UL 62368-1 and 18-75 VDC. The functional I/O-isolation system is designed to meet IEC/- EN 62368-1 with a test voltage (60 s) of 1600 VDC.
