The VLA313-2450A isolated dc/dc converter is used as a step-down dc/dc converter from a rectified ac-line between 380 and 600 Vac and a 400 to 600 Vdc input. It features a 50.4–W output at 24 V and 2.1 A. The output voltage ranges from 22.8 to 25.2 with a typical 24 V.
The dc/dc converter targets on-board pre-regulator for photovoltaic inverters and other industrial control equipment. It provides input to output isolation from 2500 Vrms for 1 min, over-current protection with automatic resume, and has an operating temperature from –20° to 55°C. The input line regulation is 100 mV and load regulation is 150 mV. ($146.24 ea — available now.)
