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_ZD-1W5&WRB_ZD-1W5 Series have been tested according to the following
recommended testing circuit before leaving factory. (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).If you want to use the products in high EMI, please
choose our metal packaged products (WRA_ZD-1W5 & WRB_ZD-1W5). General:
Cin:
24V&48V
10µF~47µF
Cout: 10µF/100mA
3) Input Current
When it is used in unregulated power supply, be sure that the fluctuating range of the power supply
and the rippled voltage do not exceed the module standard. Input current of power supply should afford the
startup current of this kind of DC/DC module. (See 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. All specifications measured at Ta=25℃, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
4. In this data sheet, 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.
