4. PRODUCT OVERVIEW AND TECHNICAL DESCRIPTION
4.1 Description
The Advance Power, Inc. Model MX28B is a modular stand-alone -48V dc power plant. It is
configurable in such a manner that it will support most typical applications within the
specified current ranges (either 200 or 400 amperes) without special application
engineering or assistance. Distribution is included for up to 24 plug-in circuit breakers.
These circuit breakers can be 1 to 100 amps, with 60-100 amp breakers requiring two
positions and a circuit breaker adapter kit. An optional low voltage disconnect (LVD) can be
provided on either the battery or the load side. A 400 amp MX28B is shown in Figure
4.1-1. A block diagram is shown in Figure 4.1–2.
