Product Details

30W isolated DC-DC converter

Ultra-wide input and regulated dual/single output

Description

URA_LD-30WR3 & URB_LD-30WR3 series of isolated 30W DC-DC converter products with an ultra-wide4:1 input voltage and feature efficiencies of up to 90%, input to output isolation is tested with 150VDC and the converters safely operate ambient temperature of -40C to +80C, input under-voltage protection, output short-circu over-voltage, over-curent protection. They met CLAS A of CISPR32/EN5032 EMI standards without external components,optional packages areoferedfor chasisor DIN-rail mounting (A2S, A4S), addtionalon alinput reverse polarityprotection and they are widely used in aplications such as data transmission device, battery power suply device, telecommunication device, distributed power suply system, hybridmodule system, remote control system, industrial robot and railway fields.

Notes: ①Use“H”suffix for heat sink mounting,“A2S”suffix for chassis mounting and“A4S”suffix for DIN-Rail mounting. We recommend to choose modules with a heat sink for enhanced heat dissipation and applications with extreme temperature requirements;

②The minimum input voltage and starting voltage of A2S and A4S Model are 1VDC higher than those of DIP package due to input reverse polarity protection function;

③Exceeding the maximum input voltage may cause permanent damage;

④Efficiency is measured at nominal input voltage and rated output load; efficiencies for A2S and A4S Model’s is decreased by 2% due to the input reverse polarity protection circuit;

⑤The specified maximum capacitive load for positive and negative output is identical.
