EMC

The EMC behavior of the device is designed for applications in industrial environments as well as residential, commercial or small business environments.

The device was tested according to EN 61000-6-1, EN 61000-6-2, EN 61000-6-3 and EN 61000-6-4.

This device complies with FCC Part 15.

Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must be able to deal with any interference received, including interference that may cause undesired operation.

The signal cables ("Active", "Ready" and "Inhibit") must be shorter than 30 m.

EMC interference emission

For standby and charging mode

Conducted interference emission, input lines

IEC/CISPR 16-1-2,
IEC/CISPR 16-2-1

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
