DESCRIPTION
The WRE-YS-1W&WRF-YS-1W Series are
specially designed for applications where a wide
range input voltage power supplies are isolated
from the input power supply in a distributed
power supply system on a circuit board.
These products apply to:
1) Where the voltage of the input power supply
is wide range (voltage range≤2:1);
2) Where isolation is necessary between input
and output(isolation voltage≤3000VDC);
3) Where the regulation of the output voltage
and the output ripple noise are demanded.

TYPICAL TEMPERATURE CURVE
1) Recommended circuit
If you want to further decrease the input/output ripple, an "LC" filtering
network may be connected to the input and output ends of the DC/DC
converter, see (Figure 1).
However, the capacitance of the output filter capacitor must be proper. If the
capacitance is too big, a startup problem might arise. For every channel of
output, provided the safe and reliable operation is ensured, the greatest
capacitance of its filter capacitor sees (Table 1). General:

24V,48V

2.2µH-10µH
10µH-22µF
2) CTRL Terminal
When open or high impedance,the converter work well; When this pin is "high"
the converter shutdown; It should be note that the input current (Ic) should
between 5-10mA,exceeding the maximum 20mA will cause permanence
damage to the converter. The value of R Can be derived as follows :
V −V −1.0
R =
Ic
3) Input current
While using unstable power source, please ensure the output voltage and
ripple voltage do not exceed indexes of the converter. The preceding power
source must be able to provide for converter sufficient starting current Ip
(Figure 2).

Use dual output simultaneously, forbid opening output pin (0V)
to use as single output.
NC:No connection
Note:
1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically.
2. Operation under 10% load will not damage the converter; However, they may not meet all specification listed.
3. All specifications measured at Ta=25 ℃, humidity<75%, nominal input voltage and rated output load unless otherwise
specified.
4. In this datasheet, all the test methods of indications are based on corporate standards.
5. Only typical models listed, other models may be different, please contact our technical person for more details.
RoHS COMPLIANT INFORMATION
This series is compatible with RoHS soldering systems with a peak wave solder temperature
of 300°C for 10 seconds.
The pin termination finish on the SIP package type is Tin Plate, Hot Dipped over Matte Tin
with Nickel Preplate. The DIP types are Matte Tin over Nickel Preplate. Both types in this
series are backward compatible with Sn/Pb soldering systems.
