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
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. 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.
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.

Parallel and Series Connection
A.Operation in Parallel
Since RSD-150 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.Increase the output voltage (current does not change). Because RSD-150 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).

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.
