TEC 3-1221

DC/DC Converter TEC 3 Series, 3 Watt • • • • Compact SIP-8 package • • • Continuous short circuit protection • 3-year product warranty I/O-isolation voltage 1‘600 VDC Fully regulated outputs Operating temperature range –40°C to +90°C Remote On/Off Designed to meet IEC/EN/UL 62368-1 (not certified) TEC 3 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 latest technology and components effectuate a high efficiency for a low thermal loss. This enables an operating temperature range from -40°C up to +90°C. The converters are fully regulated over 0 - 100% load. The low input range input is extended from 4.5 to 13.2 VDC while models are also available with the 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 IEC/EN/UL 62368-1 (not certified) with a test voltage (60 s) of 1600 VDC.
