WA25P Series AC-DC Module Power Supply is a small volume module switching power supply designed and produced by W&H-GAMAY. The module power supply has the advantages of universal input voltage range, low power consumption, high efficiency, high reliability, high safety isolation, excellent EMC performance, etc. This power supply have significant applications in many fields such as industry, office and civil. In order to meet the requirements of load application, it is necessary to refer to the recommended application circuit when it is applied in the environment with poor electromagnetic compatibility.

Note：

1. Output filter capacitors C2, C4, C6 are high-frequency and low-resistance electrolytic capacitors 6 are high-frequency and low-resistance electrolytic capacitors. For the capacity and current flowing, refer to the technical parameters provided by the manufacturer. The capacitance withstand voltage derating is more than 80%, C1, C3 and C5 to remove high-frequency noise. It is recommended to use high-frequency non polar capacitors with good high-frequency characteristics, with capacity of 1 μ F.

2. The customer's general EMC requirements use the general application circuit of Figure 1, figure 2, figure 3 or figure 4. If there are higher EMC requirements, recommended to use the circuit of Figure 5. The parameters as follows: 

    LG: 10mH-30mH common mode inductance; LC1, LC2: 100Uh-300Uh differential mode inductance. 

3. Fuse: For safety reasons, the input terminal must be connected to the fuse. The recommended specification for wa5p is 1A / 250V, wa10p-wa15p is 2A / 250V, and wa20p-wa40p is 3.15a/250v.
