7.3.2. Installing the Rectifier
The Rectifier module is the heart of the Full-Redundancy 48 VDC power system. It
converts the input AC to DC current. The Rectifier is a plugged-in module designed
specifically for modular systems. The BSPS can house up to three basic rectifiers.
To install a rectifier in the BSPS system:
1. Remove the blank panel from where you want to install an additional rectifier in
the rectifier shelf.
2. Insert the rectifier into its place with the upper and lower slides.
3. Secure the rectifier in place with 4 screws in the front panel.
4. Verify that the
ON LED is lit.
5. If there is a load on the BSPS system, verify, via the Load Bar, that there is
current sharing in the BSPS system by the rectifier.
7.3.3. Calibrating the Rectifier
The output current indication is indicated by an LED bar graph shown on the unit
front panel. This bar graph is used to verify current sharing operation between
modules fitted in the rack, and to indicate the percentage of the full load.
