450 W dc/dc converters target electric vehicles

The EVD 450 family of dc/dc converters now includes the option of using the units in parallel for redundancy or higher power requirements. The ruggedized dc/dc converters suit electric vehicle, marine, industrial and other applications which draw power from a bank of batteries or other high voltage dc source. The units are primarily used to supply power to accessories, lights, and instruments. The ‘-P’ version expands the power capability up to 900 W.

The dc/dc converter input ranges are 30 to 65 Vdc, 60 to 95 Vdc and 80 to 126 Vdc. Output voltages are 13.5 and 14.2 Vdc. The units operate at 90% efficiency. All models are isolated input to output. The isolation voltage is 2,250 Vdc. Load regulation is 7% from 20% to full load. Line regulation is ±0.02%. Ripple and noise is 250 mV peak to peak. The temperature coefficient is 0.03%/C. All models feature an on/off function for battery conservation and are protected with over voltage protection, short circuit protection, over temperature protection and is enclosed in an IP66 encapsulated 7.48 x 2.99 x 1.71-in. package.
