DC/DC Converter TEC 3WI Series, 3 Watt

  • Compact SIP-8 package
  • I/O-isolation voltage 1‘600 VDC
  • Ultra-wide 4:1 input voltage range
  • Fully regulated outputs
  • Operating temperature range –40°C to + 90°C
  • Continuous short circuit protection
  • Remote On/Off
  • 3-year product warranty
  • Designed to meet UL 62368-1 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 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 (no minimum load is re- quired). The models are available with ultra-wide input ranges of 4.5-18, 9-36 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.
