APPLICATIONS
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 (namely full 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 data sheet, 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.
