About the product
The RMD300 series DC/DC converter, which can be mounted in a housing, is designed for rail vehicles and transportation applications and complies with all relevant standards: EN50155, EN50121-3-2, DB-EMV06, EN50124-1, EN50125-1, EN61373 1B, EN62368-1, EN45545-2. RDM300 covers a 12:1 input voltage range from 16.8VDC to 137.5VDC and provides an isolated and regulated 24V output with reinforced isolation system. The mounting on a base plate allows a wide operating temperature range for class OT4+ST1&ST2 from -40°C to +85°C without degradation of performance. Input reverse polarity protection, inrush current limitation, 10 ms bridging time, remote control and output OR-ing diode and an efficiency of up to 94.8 % round off the functionality of this fully rail-compatible plug & play device.
