DC/DC Converter TEC 3 Series, 3 Watt Compact SIP-8 package I/O-isolation voltage 1600 VDC Fully regulated outputs Operating temperature range 40C to TEC 3 is a new series with the design purpose to improve the prevalent 3 Watt +90C SIP-8 DC/DC converters in terms of cost, efficiency and performance. The lat- est technology and components effectuate a high efficiency for a low thermal Continuous short circuit protection loss. This enables an operating temperature range from -40C up to +90C. Remote On/Off The converters are fully regulated over 0 - 100% load. The low input range in- put is extended from 4.5 to 13.2 VDC while models are also available with the 3-year product warranty standard 2:1 input ranges of 9-18, 18-36 and 36-75 VDC (see TEC 3WI series for 4:1 input ranges). The functional I/O-isolation system is designed to meet Designed to meet UL 62368-1 IEC/EN 62368-1 with a test voltage (60 s) of 1600 VDC.
