TEC 2/TEC 3 DC/DC Converters

TRACO Power TEC 2 and TEC 3 Series 2W and 3W DC/DC Converters feature an industry-standard SIP-8 package and are available with a wide 2:1 input range or an ultra-wide 4:1 input range (WI suffix). The TEC 2 and TEC 3 DC/DC Converters are designed as a cost-effective solution with increased performance to existing 2W and 3W SIP packages. These converters deliver high efficiencies with low thermal loss over a wide temperature range and are fully regulated over a 0 to 100% load with no minimum load required. TEC 2 and TEC 3 provide a functional I/O-isolation system approved to IEC/EN 60950-1 with a test voltage (60s) of 1600VDC.
