8 MX28B 4.2 Power Output Capacity The power plant has two basic configurations: The first supplies a maximum of 200 amps or 150 amps with N+1 redundancy. The housing for this configuration provides space for one rectifier shelf that can hold up to four rectifiers, a control unit, and one tier of up to 24 distribution circuit breakers.
MX28B 9 • Control of either a battery or a load LVD 4.5 AC Input Power Each rectifier requires 208/220/240V ac, single-phase, 50/60 Hz, supplied through an external 20-amp two-pole breaker.
10 MX28B 4.7 DC Distribution A standard 24-position plug-in circuit breaker tier provides -48V distribution. The breaker tier is connected at its center to the -48V dc bus, and each side has an ampacity of 300A.
