Traco Power DC-DC Converter, 4:1 Input Range, 3kV DC Isolation Voltage - TMR 3WIR Series - TMR 3-7212WIR


Dial down voltages with this DC-DC converter from Traco Power. With a wide 4:1 range, it takes inputs between 43 and 160V DC and produces a lower output of 12V DC. This makes it a good match for powering electronic equipment in commercial and industrial applications. As it meets standard EN 50155, you can be sure it's safe for railway applications. A high isolation voltage of 3kV DC ensures your input and output are kept separate, to ensure your circuits work reliably. Peak to peak, the ripple and noise are limited to 75mV. This reduces interference and boosts the converter's dependability.

Features & Benefits


• Dimensions of 21.8 (L) x 9.6 (W) x 11.2mm (D) for a neat fit in busy setups

• Efficiency of 82% means it wastes minimal energy doing its job

• Remote On/Off function to help electronics save power

• Operates at temperatures up to +78°C without loss of performance

Applications


• Consumer electronics

• Telecommunications networks

• Industrial computing

How do I mount this DC-DC converter?
