Technical data
7.1.3
Mains voltage 3AC 380-480V
NOTE:
The rated currents in given ambient temperatures (in Table 32) are achieved only when
the switching frequency is equal to or less than the factory default.
7.1.4
Definitions of overloadability
Overloadability
=Following continuous operation at rated output current I
N
, the converter supplies
150% * I
N
for 1 min, followed by a period of at least 9 min at I
N
or below.
Example:
If the duty cycle requires 150% rated current for 1 min in every 10 min, the remaining 9
min must be at rated current I
N
or less.
