in operation with factory-set current controller clock cycles
Permissible output current as a function of ambient temperature
SINAMICS G150 converters and associated system components are rated for an ambient temperature of 40 C and
installation altitudes of up to 2000 m above sea level. The output current of SINAMICS G150 converters must be
reduced (current derating) if they are operated at ambient temperatures above 40 C. G150 cabinet units are not
permitted to operate at ambient temperatures in excess of 50 C. The tables below state the permissible output
current as a function of the ambient temperature for different degrees of protection.
