Series KR

20W Isolated Regulated Low Profile DC-DC Converter

The KR series is an isolated/regulated DC-DC converter with wide input range, tight regulation and six-sided shielded case. These modules have trimming and control features. Single and dual isolated output models are standard. They can operate up to 20W over the temperature range of -25°C to +70°C without derating, a heat sink or active cooling.
