TRN1 & TRN3 Ultra-Compact DC/DC Converters

TRACO Power TRN1 and TRN3 Ultra-Compact DC/DC Converters are fully regulated, featuring optimized efficiency and thermal management. This engineering enables a package size as small as 11.9mm x 7.7mm x 11.0mm, offering both compact SIP or SMD versions. These high-performance DC/DC converters provide short circuit protection, supporting 1600VDC I/O-isolation and a wide range of input voltages (2:1) with no minimum load required. TRACO Power TRN1 and TRN3 DC/DC Converters come with a three-year product warranty and have an operating temperature range of -40°C to + 85°C (TRN3) and -40°C to +90°C (TRN1) with derating and full power, convection cooled to +65°C in 3W and +90C in the 1W.
