CHAPTER 1: PRODUCT DESCRIPTION

Part Number Description

MNDC -48 VDC to 24V, 3.6A True Load Sharing Redundant Power Supply

MNDCCM -48 VDC to 24V, 3.6A Power Supply with Current Monitor

PRODUCT DESCRIPTION

1. Product Description

The MNAC and MNDC are modular power supplies that supply the required +24 VDC to the MAXNET Active Chassis
backplane. This allows any MAXNET active module (AMP’s, RF Switch) to be installed in any remaining active chassis slot
to receive power. Both MNAC and MNDC have 24 VDC redundant powering capabilities, although only the MNDC provides
true load sharing. Installing two power supply modules into the chassis will maintain power to the backplane in the event that
one of them fails. Both the MNAC and the MNDC include a 24 VDC rear terminal block connection for the remote chassis
powering options. They are connected to the Active MAXNET Chassis through a hot-swapping backplane. The MNAC and
MNDC modules feature front panel LED power indication and +24 VDC backplane voltage monitor connections.

In addition to the standard powering modules, an optional current monitoring function is available in both the MNAC and

MNDC to provide remote indication (via the rear terminal block) of current uctuations caused by an active module failure.

The MNRPS is a module that supplies power to an Active MAXNET Chassis backplane from a remote 24 VDC source. It
features front panel LED power indication and +24 VDC backplane voltage monitor connections.
