Input Reverse Polarity Protection
Input Range and Transient Ability
Input Under-Voltage Protection
Inrush Current
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.
The series has a wide range input capability. With 40% of rated input voltage, it can withstand that for 1 second.±
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.
Inrush current is suppressed by a resistor during the initial start-up, and then the resistor is bypassed by a MOSFET to reduce power
consumption after accomplishing the start-up.

Efficiency vs Load & Vin Curve
The efficiency vs load & Vin curves of each model are shown as below.
Parallel and Series Connection
A.Operation in Parallel
Since RSD-30 series don't have built-in parallel circuit, it can only use external circuits to achieve the redundant operation but not increase the current rating.
1.Add a diode at the positive-output of each power supply (as shown as below), the current rating of the diode should be larger than the maximum output current rating
and attached to a suitable heat sink. This is only for redundant use (increase the reliability of the system) and users have to check suitability of the circuit by themselves.

30W Reliable Railway DC-DC Converter RSD-30 series
Over Voltage Protection
LED Indicator
The converter shuts off to protect itself when the output voltage drawn exceeds 115~140% of its output rating. It must be repowered on to recover.
Equipped with a built-in LED indicator, the converter provides an easy way for users to check its condition through the LED indicator.
Green : normal operation; No signal: no power or failure.
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).

Overload Protection
If the output draw up to 105~135% of its output power rating, the converter will go into overload protection which is constant current mode. After the faulty condition
is removed, it will recover automatically. Please refer to the diagram below for the detail operation characteristic. Please note that it's not suitable to operate within
the overload region continuously, or it may cause to over temperature and reduce the life of the power supply unit or even damage it.

and RSD-30 series must be firmly mounted at the center of the 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
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.
