PAN-SERIES
Ⅵ Connection-1. [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.
ⅥConform to EN55011/55022, VCCI Class A
ⅷClass-A Application
PAN4820+PAF500F
ⅥConform to EN55011/55022, VCCI Class B
ⅷClass-B Application
PAN4820+PAF500F+adding external components(Capacitor: Net 3)
Recommended Values C1: 22µF (Ceramic Capacitor)
C2,3: 0.47µF(Film or Ceramic Capacitor)
Remark) Above connection conforms to each standard in our test condition by combining PAN series with our power modules (PAF500F48
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
Ⅵ 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.
