Equivalent & Substitute Parts Reference: RTD-1524/HP
Part Overview
The Recom Power RTD-1524/HP is an isolated module DC-DC converter designed for ITE (Commercial) and Medical applications. It offers dual outputs of +24V and -24V at 42mA each, operating within a 13.5V to 16.5V input range, featuring 3 kV isolation and SCP (short circuit protection). This part is classified as obsolete. As a result, identifying compatible substitute models with identical electrical and mechanical parameters is necessary for continued hardware design, repair, or replacement.
