DESIGN CONSIDERATIONS
1) Requirement on output load
To ensure this module can operate efficiently and reliably, During operation, the minimum output load
could not be less than 10% of the full load.
If
the actual output power is very small, please connect a resistor with proper resistance at the output end in parallel to increase the load, or use our
company’s products with a lower rated output power.
2) Overload Protection
Under normal operating conditions, the output circuit of these products has no protection against overload. The simplest method is add a circuit
breaker to the circuit.
3) Recommended circuit
All the VRA_D-5W&VRB_D-5W Series have been tested according to the following recommended testing circuit before leaving factory. This series
should be tested under load. Never be tested under no load (see Figure 3).
If you want to further decrease the output ripple, you can increase capacitance properly or choose capacitors with low ESR. However, the capacitance
can’t exceed the maximum capacitor load in the list (Table 1).

Note: For each output.
4) No parallel connection or plug and play
Note:
1. The load shouldn't be less than 10%, otherwise ripple will increase dramatically. Operation under minimum load will not damage the converter;
However, they may not meet all specification listed, and that will reduce the life of product.
2. Max. Capacitive Load tested at nominal input voltage, full load and constant resistive load.
3. All specifications measured at Ta=25°C, 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.
6. Our company offer custom products.
7. Specifications subject to change without notice.
