APPLICATIONS
40
The WRA_ZMD-6W & WRB_ZMD-6W 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≤4:1);
2) Where isolation is necessary between input and
output(isolation voltage≤1500VDC);
3) Where the regulation of the output voltage and the
output ripple noise are demanded.

RECOMMENDED CIRCUIT
APPLICATION NOTE
1) Requirement on output load
In order to ensure the product operate efficiently and reliably, in addition to a max load (namelyull load),
a minimum load is specified for this kind of DC/DC converter. Make sure the specified range of input
voltage is not exceeded, the minimum output load no less than 10% load. If the actual load is less than the
specified minimum load, the output ripple may increase sharply while its efficiency and reliability will
reduce greatly. If the actual output power is very small, please add an appropriate resistor as extra loading,
or contact our company for other lower output power products.
2) Recommended Circuit
All the WRA_ZMD-6W
& WRB_ZMD-6W series have been tested according to the following
recommended testing circuit before leaving factory. This series should be tested under load (see Figure 1).
If you want to further decrease the input/output ripple, you can increase capacitance properly or
choose capacitors with low ESR. However, the capacitance should not be too high, or may cause start-up
problem. For every channel of output, provided the safe and reliable operation is ensured, the greatest
capacitance of its filter capacitor sees (Table 1). General:
Cin:
24V&48V
10µF~47µF
Cout: 10µF/100mA
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).
General: Ip ≤1.4*Iin-max
4) No parallel connection or plug and play

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. Capacitor MAX load tested at input voltage range and full load.
4. All specifications measured at Ta=25℃, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
5. In this datasheet, all the test methods of indications are based on corporate standards.
6. 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.
