Power requirements
This section describes AC power and DC power source requirements for the cabinet.
Global AC MCC power supply
The Global MCC (GMCC) power supply is for use in both US and international systems. The
GMCC replaces the existing AC MCC1 cabinet configuration which is used in the US. This
replacement reduces the number of power supplies and distribution units that are associated
with the MCC1 platform.
The GMCC automatically accepts 200 VAC to 240 VAC power at 50 Hz or 60 Hz. The GMCC
complies with all emissions and safety requirements for customer applications worldwide. The
GMCC power system consists of:
● An NP850 rectifier that consists of cabinet-level power units located in the
power-distribution unit at the bottom of the MCC1
● 649A power supplies the DC-to-DC converters that provide carrier-level power
● One battery interface and alarm unit
● Battery connections
● Alarm outputs
