NOTE	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. Strongly recommended that external output capacitance should not exceed 5000uF. (Only for: RSD-100-5 / -12) 5. The power supply is considered a component that will be installed into the 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) 6. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft). ※ Product Liability Disclaimer： For detailed information, please refer to https://www.meanwell.com/serviceDisclaimer.aspx

Mechanical Specification

Block Diagram

Input Fuse

There is one fuse connected in series to the positive input line, which is used to protect against abnormal surge. Fuse specifications of each model are shown as below.

Type	Fuse Type	Reference and Rating
B	Time-Lag	Conquer UDA-A, 10A, 250V
C	Time-Lag	Conquer UDA-A, 5A, 250V
D	Time-Lag	Conquer UDA-A, 3.15A, 250V

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

EN50155: 2007 version -D type complies with S2 level, while B and C types comply with S1 level at full load output condition. To fulfil the This function is optional, which the standard product does not have it. If you do need the function, please contact MW for details. requirements of S2 level, B and C types require de-rating their output load to 70%, please refer to the curve diagrams below.

Output Voltage Adjustment
This function is optional, which the standard product does not have it. If you do need the function, please contact MW for details.

Efficiency vs Load & Vin Curve

The efficiency vs load & Vin curves of each model are shown as below.

Parallel and Series Connection

Operation in Parallel

Since the RSD-100 series doesn’t have a built-in parallel circuit, it can only use external circuits to achieve redundant operation but not increase the current rating.

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 the suitability of the circuit by themselves.

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.

Operation in Series

RSD-100 can be operated in series. Here are the methods of doing it:

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.
Increase the output voltage (current does not change). Because the RSD-100 series have no reverse blocking diode in the unit, you should add an external blocking diode to prevent 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 draws 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 characteristics. 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 115~140% of its output rating. It must be repowered on to recover.

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

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 conditions. It requires a de-rating output current when the ambient temperature is between 55-70℃, please refer to the de-rating curve below.

Suitable installation methods are shown as below. Since RSD-100 is a semi-potted model, its thermal performances for the following installation methods are similar and share the same derating curve.

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℃, the RSD-100 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 the RSD-100 series must be firmly mounted at the center of the iron plate.

The load vs ambient temperature curve is shown as below.

Suitable installation methods are shown as below. Since RSD-100 is a semi-potted model, its thermal performances for the following installation methods are similar and share the same derating curve.
