[Basic Connection] In input/output of power modules, please connect resistor/capacitor properly as we recommend in our instruction manuals for power modules. Fuse is not included in the unit, so please install appropriate fuse in input side as guided in our instruction manual of power modules. 100 110 0.15 0.5 1 5 10 30.405 EN55022 Class B [AEN55022 Class B [AV]V]EN55022 Class B [AV] Frequency(MHz) Conducted Emission Level (dBuV) m Connection-2. [Other method of connection] (With baseplate and -V of power module grounded) This noise filter will provide you with the best performance with the condition of baseplate and output (+V or -V) non-grounded. If baseplate and output (+V or -V) need to be grounded, connect C1, C2, and C3 shown in the above. Remark) Above connection conforms to each standard in our test condition by combining PAN series with our power modules (PAF500F 48 series or PAH200H48 series). In some cases concerned with below mentioned or the like, PAN series will not conform to the standards. So, please be sure to measure EMI values (noise terminal voltage, noise electrolysis intensity) with actual equipment. - Quantity of power modules connected / model structure / load condition - Wiring method of input and output - Surrounding circuits
