NOTE
The use of the commutating choke BK3-0025/0030, I
nom
= 25 A, L = 1,18 mH with
copper busbar part no. 368377 or with terminals part no. 399136 is recommended, if
the device BUM60-12/24 operates at full capacity.
Reason:
The ripple current through the DC link capacitor is high, if the device operates at full
capacity. The current can be reduced by connecting ahead a commutating induc
-
tance accordingly the DC link capacitor load is reduced and therefore is heated up to
a lesser extent and a longer live cycle of the DC link capacitors can be expected than
by operating the device on the power limit without using a commutating choke.
