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.
Switching Frequency
The buffer module has two converters with variable frequencies included.
6 to 610kHz Charging converter at 24V input (is only active during charging)
The frequency depends on the state of charge of the capacitors
10 to 70kHz Buffer converter at buffering at 22.5V
The frequency depends on the output current. The values are
between 10% and 100% of the nominal buffer current
