DC/DC Converter TRS 2 Series, 2 Watt Most compact 2 Watt SMD DC/DC converter: 11.9 mm x 11.3 mm x 8 mm (0.47 x 0.44 x 0.31 inch) Cost-efficient design 1600 VDC I/O isolation (functional) TRS 2 Series is a new series with the design purpose to improve the prevalent 2 Watt SMD High efficiency for low thermal loss DC/DC converters in terms of size, cost, efficiency and performance. The main intended Operating temperature range uses for the TRS 2 Series are IT applications, industrial control systems and also measure- -40C to +90C ment equipment. With the reduction of thermal loss, the operating temperature range can be expanded from -40C to +90C. The converters are fully regulated over 0 - 100% load Designed to met UL 62368-1 (no minimum load is required). The low input range is extended from 4.5 to 13.2 VDC (to No minimum load required include 12V battery powered applications) while models are also available with the stan- Protection against short circuit dard 2:1 input ranges of 9-18, 18-36 and 36-75 VDC. The functional I/O-isolation system is designed to meet IEC/EN 62368-1 with a test voltage (60 s) of 1600 VDC. 3 years product warranty Models Order code Input voltage Output voltage Output current max.
