TMR 4 and TMR 4WI DC/DC Converters
TRACO Power’s two families of regulated DC/DC converters come in a compact SIP-8 package
TRACO Power's TMR 4 (2:1 input range) and TMR 4WI (4:1 input range) are two families of regulated 4W DC/DC converters with either single- or dual-output voltages ranging from 5 VDC to 24 VDC. Each comes in a compact SIP-8 package featuring I/O isolation of 1600 VDC and protection against short-circuit and overload. The advanced design provides efficiencies up to 87%, an operating temperature range of -40°C to +70°C without derating, and an integrated remote on/off function. Safety approved to the latest IEC/EN/UL 62368-1 industrial standard, these DC/DC converters deliver a high-quality, cost-efficient solution and provide a cost-efficient alternative to 6 W converters in 3 W to 4 W applications.
