EMC interference emission | For standby and charging mode | |
|---|---|---|
Conducted interference emission, input lines | IEC/CISPR 16-1-2, | Limit values for DC power supply connections according to EN 61000-6-3 fulfilled |
Interference emission | EN 55011, | Class B |
Switching frequencies | ||
|---|---|---|
Charge converter on 48 V input (is only active during charging) | 6 to 740 kHz | The frequency depends on the charge state of the capacitors |
Buffer converter when buffering at 45 V | 10 to 85 kHz | The frequency depends on the output current. The values are valid between 10% and 100% of the nominal buffer current |
