DESCRIPTION

The DCPSR2 series of non-isolated DC/DC converters offers up to 30 watts of output

power in an ultra-compact package with an optional heatsink. This series consists of

single output models with wide input voltage ranges and low standby power. Each model

in this series has over load, short circuit, and over temperature protection, is RoHS &

REACH compliant, and has UL60950-1, EN60950-1, and IEC60950-1 safety approvals.
