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.

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.

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 – L/H type is in compliance with S2 level (10ms), while G types are in compliance with S1 level (3ms) at full load output This function is optional, which the standard product does not have it.
• If you do need the function, please contact MW for details. condition. To fulfil the requirements of S2 level (10ms), G types require de-rating their output load to 50%, please refer to the curve diagrams below.
• EN50155: 2017 version – Comply with S1 level (3ms)

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

A.Operation in Parallel
Since RSD-60 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-60 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-60 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 115~140% 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

• 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-60 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-60 series must b ℃ e 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-60 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-60 is a semi-potted model, its thermal performances for the following installation methods are similar and share the same derating curve.
