■ Model Encoding

■ Description

RSD-30 is a 30W enclosed type DC-DC reliable railway converter. This series is compliant with EN50155/

IEC60571 railway standard, constituting three types of models with 4:1 wide but different input ranges

9~36V/18~72V/40~160V, suitable for railway and all kinds of transportation systems exploiting the frequently

used standard input voltages such as 12V, 24V, 36V, 48V, 72V, 96V and 110V. Various output voltages,

3.3V, 5V, 12V and 24V are available for selection.

This series has the capability of working under -40~+70 , low ripple and noise, supreme EMC characteristics, ℃

4KVDC I/P-OP, low enclosure profile 25mm and an interior with semi-potted silicone. It does not only well

fits the in-car systems or the facilities by rails for railway, trams and buses but also can be used in the harsh

environment with high vibration, high dust, extremely low or high temperature, etc.

30W Reliable Railway DC-DC Converter RSD-30 series 2.Increase the output voltage (current does not change). Because RSD-30 series have no reverse blocking diode in the unit, you should add an external blocking diode to prevent the damage of every unit while starting up. The voltage rating of the external diode should be larger than V1+V2 (as shown as below).

RSD-30 30W Reliable Railway DC-DC Converter series Suitable installation methods are shown as below. Since RSD-30 is a semi-potted model, its thermal performances for the following installation methods are similar and share the same derating curve. b.Operate with additional iron plate If it is necessary to fulfil the requirements of EN50155 TX level that operate the unit fully-loaded at 70℃, RSD-30 series must be installed onto an iron plate on the bottom.
