The WRA_ZP-3WR2 & WRB_ZP-3WR2 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. For these DC-DC converters, you can reduce the failure points of design, and save the manpower,
material and time cost in developing micro power supply, and also ensure better
quality, stability, safety protection, and reliability for the end products.
These products apply to where:
1) Input voltage range ≤2:1;
2) 1.5KVDC input and output isolation;
3) Output regulated and low ripple noise is required.
In circuits such as industrial control, electric power, communication system power supply, etc.
Design Reference
1. Output load requirements
To ensure that the module can work efficiently and reliably, its output min. load shall be no lower than 5% of the rated load when using, or
the output ripple may increase rapidly. Ensure that the product working load must be higher than 5% of the rated load.
2. Typical application
All the DC/DC converters of this series are tested according to the recommended circuit before delivery.
If it is required to further reduce input and output ripple, properly increase the input & output of additional capacitors Cin and Cout or
select capacitors of low equivalent impedance provided that the capacitance is no larger than the max. capacitive load of the product.
