MX28B-1200+27V PRODUCT MANUAL

4 PRODUCT OVERVIEW AND TECHNICAL DESCRIPTION

4.1 Description

The APC Models MX28B1200+27V represents a family of stand-alone +24V DC power plants. Through the use of modular power, a system is configurable in such a manner that it will support most typical applications within the specified current range of up to 1200 amps without special application engineering or assistance. The expansion bay, which will increase the output to 2400 Amps, will be available shortly.

The system is capable of supplying 1200 amps of +24V DC power in a single frame with integrated power distribution and an advanced control and monitoring module. Standard distribution for a power bay includes up to 38 plug-in circuit breakers ranging from 1 to 100 amps. An optional +24V to -48V Converter shelf is available to power up to 80 Amps of –48V loads that can be distributed by up to 7 circuit breakers. An optional low voltage disconnect (LVD) can be provided on the battery side. A 1200 amp MX28B+27V with converters is shown in. Figure 4-1. A block diagram is shown in Figure 4–2
