Radiated emission EN 55011, EN 55022 Class B
This device complies with FCC Part 15 rules.
Operation is subjected to following two conditions: (1) this device may not cause harmful interference, and (2) this
device must accept any interference received, including interference that may cause undesired operation.
***) Not relevant due to short wire length
Switching Frequency
The DC-UPS has four converters included, three operate with the same switching
frequency.
100kHz Buck-boost converter and battery charger
45 to 80kHz Auxiliary converter,
switching frequency is input voltage dependent
