MX28B 7 Figure 4.1 - 2 . MX28B BLOCK DIAGRAM.
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.
MX28B 11 4.10 Mechanical Dimensions: 15.75” high x 23” wide x 17.5” deep (200 amp unit) 22.75” high x 23” wide x 17.5” deep (400 amp unit ) Weight: Housing - 85 lbs.
12 MX28B 5. INSTALLATION PROCEDURES 5.1 Preparation 5.1.1 Recommended Tools • Standard selection of insulated hand tools. • Proper tools for crimping the selected cable lugs.
MX28B 13 5.1.6 Mounting Both front mounting on standard 23-inch rails and optional wall mounting are available. 5.1.7 Ventilation The rectifiers have fans that provide front to rear airflow for internal cooling. The MX28B housing should mounted such that there is free airflow to the front, top, and bottom of the unit.
14 MX28B cable(s) must also carry the full load current during battery operation. If assistance is required to determine the necessary cables for the application, contact your sales representative or Advance Power, Inc. 5.3.3 Connecting the Cables The battery cable connections are located at the top rear of the unit as shown in Figure 4.
