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.

2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load regulation.
4. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on
a 360mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to
perform these EMC tests, please refer to EMI testing of component power supplies. (as available on http://www.meanwell.com)

Input Reverse Polarity Protection
There is a MOSFET connected in series to the negative input line. If the input polarity is connected reversely, the MOSFET opens and there
will be no output to protect the unit.
Input Range and Transient Ability
The series has a wide range input capability. With
±
40% of rated input voltage, it can withstand that for 1 second.
Input Under-Voltage Protection
If input voltage drops below Vimin, the internal control IC shuts down and there is no output voltage. It recovers automatically when input
voltage reaches above Vimin, please refer to the cruve below.
