Description
The HILR series is an isolated DC-DC converter with wide and high input voltage range between 125 – 475 VDC, tight regulation, low ripple and low profile – 0.500″ height. These modules are fully protected from input over/undervoltage, output overcurrent, and over temperature. Shutdown feature, single and dual isolated output models are standard. They can operate over the temperature range of -25°C to +70°C without derating, a heat sink or active cooling.
