Series LR render 1

Series LR

5W Isolated Regulated Low Profile DC-DC Converter

The LR series is an isolated DC-DC converter with wide input range, tight regulation and six-sided shielded case. These modules have trim and control features. Single and dual isolated output models are standard. They can operate up to 5W over the temperature range of -25°C to +70°C without derating, a heat sink or active cooling.
