MCA Power Share Feature: The MCA Power Share feature allows you to connect the Spec. No. 582140000 Power
System to an existing DC power system instead of extending or completely replacing the existing power system.
The MCA Power Share feature provides for the sharing of the total load in a controlled manner. When Power Share
is programmed, the MCA in the 582140000 Power System adjusts rectifier output voltage per load demands to
ensure proper sharing between the two systems. For further information, request Application Note AN38.
4.1.11
MCA Alternate Current Limit Feature: The MCA Alternate Current Limit feature provides a means to limit the
output current of all rectifiers based on the state of an external signal. The rectifiers output current is limited to a
percentage of rectifier output capacity as configured by the user. A binary input on an installed MCA I/O circuit
card is used to monitor the external signal that triggers the current limiting action.
