1. All parameters NOT specially mentioned are measured at 24,48,110VDC input, rated load and 25℃ of ambient temperature.
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. 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)
5. Strongly recommended that external output capacitance should not exceed 5000uF.

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. Within ±30% of rated input voltage, it can be executed at full-load operation and operate properly; 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.

Inrush Current
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.
Hold-up Time
D type is in compliance with S2 level, while B and C types are in compliance with S1 level at full load output condition. To fulfil the requirements of S2 level, B and C
types require de-rating their output load to 70%, please refer to the curve diagrams below.

Parallel and Series Connection
A.Operation in Parallel
Since RSD-200 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.

2.When using S.P.S. in parallel connection, the leakage current will increase at the same time. This could pose as a shock hazard for the user. So please contact the
supplier if you have this kind of application.
B.Operation in Series
RSD-200 can be operated in series. Here are the methods of doing it:
1.Positive and negative terminals are connected as shown as below. According to the connection, you can get the positive and negative output voltages for your loads.

2.Increase the output voltage (current does not change). Because RSD-200 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.

Over Voltage Protection
The converter shuts off to protect itself when the output voltage drawn exceeds 115~135% of its output rating. It must be repowered on to recover.
Over Temperature Protection
The converter shuts off to protect itself when the built-in temperature sensor mounted on the main power transformer senses a high temperature. The output recovers
automatically if the temperature drops below the limit.
LED Indicator
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.
Derating Curve
a.Single unit operation
If the unit has no iron plate mounted on its bottom, the maximum ambient temperature for the unit will be 55℃ as operating under full load condition. It requires
de-rating output current when ambient temperature is between 55-70℃, please refer to the de-rating curve as below.

Suitable installation methods are shown as below. Since RSD-200 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-200 series must be installed onto an iron plate on
the bottom. The size of the suggested iron plate is shown as below. In order for optimal thermal performance, the iron plate must have an even & smooth surface
and RSD-200 series must be firmly mounted at the center of the iron plate.
