Note
Principle of the precharging circuit
SINAMICS PM330 Power Modules include a half
-controlled thyristor bridge as rectifier
circuit. As a result of the precharging principle with phase control, precharging is only started
when all of the enable signals are available and by setting the ON/OFF co
mmand
= 1).
The DC link is then fully charged after approximately 400
ms.
The Power Modules can be used with the following Control Units, including all
communication versions with firmware version from 4.6 HF7 and higher.
CU230P-2 PN
-0BB30-1FAx
CU230P-2 DP
-0BB30-1PAx
CU230P-2 HVAC
-0BB30-1HAx
Operation with Control Units other than those listed above is not permitted.
