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.

Hold-up Time
H type is in compliance with S2 level (10ms), while G and L types are in compliance with S1 level (3ms) at full load output condition.
To fulfil the requirements of S2 level (10ms), G types require de-rating their output load to 80%, please refer to the curve diagrams below.

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.

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
B.Operation in Series
RSD-30 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.
