TMR 4 & TMR 4WI Regulated 4W DC-DC Converters

TRACO Power TMR 4 and TMR 4WI Series Regulated 4W DC-DC Converters are available with 2:1 (TMR 4) or 4:1 (TMR 4WI) input ranges in a compact SIP-8 package. The converters are available with either single or dual output voltages ranging from 5V_DC to 24V_DC. The series has 1600V_DC of I/O isolation voltage and features short-circuit and overload protection. The converters offer up to 87% efficiency and have a temperature range of -40°C to +70°C without derating. TRACO Power TMR 4 and TMR 4WI Series Regulated 4W DC-DC Converters are certified according to the latest IEC/EN/UL 62368-1 industrial standard.
