Note: ① Series with suffix “H” are heat sink mounting, series with suffix "A2S" are chassis mounting, with suffix "A4S" are DIN-Rail mounting, for example
URB2405YMD-20WHA2S is chassis mounting with heat sink, URB2405YMD-20WA4S is DIN-Rail mounting without heat sink. If the application has a higher
requirement for heat dissipation, you can choose modules with heat sink.
②Absolute maximum rating without damage on the converter, but it isn't recommended.
③The efficiency of "A2S" and "A4S" is approx. 2% lower for the protection of inverse polarity.

DESIGN CONSIDERATIONS
① Recommended circuit
All the URB_YMD-20W Series have been tested according to the following recommended testing circuit before leaving factory (see Figure 4)
The product must be tested with load.
If you want to further decrease the input surge voltage and the output ripple, you can increase a capacitance properly or choose capacitors with
low ESR .It should also be noted that the capacitance of filter capacitor must be proper. If the capacitance is too big, a startup problem might arise.
For every channel of output, provided the safe and reliable operation is ensured, the recommended capacitance of its filter capacitor sees (Table 2).

②It is not recommended to increase the output power capability by connecting two or more converters in parallel. The product is not
hot-swappable.
Note:
1. Min. load shouldn't be less than 5%, otherwise ripple maybe increased dramatically, If the product operates under min. load, it may not be
guaranteed to meet all specifications listed. Operation under minimum load will not damage the converter.
2. Recommended Dual output models unbalanced load is ≤±5%, If the product operates >±5%, it may not be guaranteed to meet all specifications
listed. Please contact our technical support for more details.
3. Max. Capacitive Load is tested at input voltage range and full load.
4. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage and rated output load unless otherwise specified.
5. In this datasheet, all test methods are based on our corporate standards.
6. All characteristics are for listed models, and non-standard models may perform differently. Please contact our technical support for more details.
7. Please contact our technical support for any specific requirement.
8. Specifications of this product are subject to changes without prior notice.
