Notes: 1. The standard modules meet either EMI Class A or Class B with external components. For further information, please contact Polytron Devices.
Notes: 2. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. The filter suggested:
The SWBR6-12XX recommended an aluminum electrolytic capacitor (Nippon chemi-con KY series, 220μF/100V) and a TVS (SMDJ70A, 70V, 3000Watt peak pulse power) to connect in parallel.
The SWBR6-48XX recommended an aluminum electrolytic capacitor (Nippon chemi-con KY series, 220μF/ 100V) and a TVS (SMDJ120A, 120V, 3000Watt peak pulse power) to connect in parallel.
The SWBR6-110XX recommended an aluminum electrolytic capacitor (Nippon chemi-con KXJ series, 150μF/ 200V) and a TVS (SMB250A, 250V, 600Watt peak pulse power) to connect in parallel.
CAUTION: This power module is not internally fused. An input line fuse must always be used.
