MX28B-1200+27V PRODUCT MANUAL

Rev 1

4.5 Control Unit

The microprocessor-based power system control unit is 1U high (1.75”) and provides control and monitoring functions. Features implemented are:

∙32-character alphanumeric display (2 lines by 16 characters)

∙LED alarm and status indicators

∙Standard voltage and battery charging control

∙Battery temperature compensation (optional temperature probe)

∙Monitoring of up to 6 shelves of four rectifiers each and up to 8 DC to DC Converters

∙Individual alarm monitoring of 72 breakers

∙Individual alarm monitoring of 16 power distribution fuses

∙Eight alarm / annunciation relays (Major, Minor, and six user defined) with form C contact outputs

∙Four external alarm inputs (either N.O. or N.C. contacts)

∙Control for two independent Low Voltage Disconnects (LVD’s)

∙WEB/SNMP Interface Card for remote monitoring

4.6AC Input Power

Each rectifier shelf requires 208/220/240V ac, single -phase, 50/60 Hz, supplied through an external 80-amp breaker. Three Vertical wire conduits in the left rear of the frame provide routing for AC input power connection of each shelf. The Earth Ground wiring is factory installed to each rectifier shelf. A power entry box with 3 pilot holes is provided at the top and rear of the frame where AC wiring conduit can be run. Refer to Figure 4-3.
