MX06 Power Plant User’s Manual Page 17
4 Technical Description
The various MX06 models are modular stand-alone –48 V dc power plants. Each can be
configured to support most typical applications within their specified current capacity without
special application engineering or assistance. Output distribution is provided through the use of
up to 12 plug-in GMT-type fuses per shelf or up to two circuit breakers per shelf. A control port
is also available to operate an optional motorized circuit breaker designed to provide battery
cable protection and low voltage disconnect (LVD) for a battery string(s).
4.1. Rectifier Management
AC Input Power
The basic component of the power system is the rectifier module, which rectifies utility AC into
nominal 48 Volts DC. Each rectifier module requires 90/115/208/220/240 Volt AC single-phase,
50/60 Hz. Available cord sets include a variety of blade and twist lock plugs. Dedicated wiring
inside conduit can also be used.
DC Output Power
The DC outputs of all the rectifiers in the system are connected to a common bus that is rated to
carry the current of the entire system. The rectifier modules will equally share the entire load,
independent of the controller. The rectifiers will continue to provide DC power if the controller is
removed or fails.
System Output Capacity
The power plant has two basic configurations:
The MX06 50 power plant supplies a maximum of 52.5 amps or 42 amps with N+1 redundancy.
The housing for this configuration provides one rectifier shelf with integrated DC output
distribution, and controller.
The MX06-100 power plant supplies a maximum of 105 amps or 94.5 amps with N+1
redundancy. The housing for this configuration provides two rectifier shelves with integrated DC
output distribution, and controller.
Rectifier alarms reporting
The rectifier has numerous sensors inside the unit that monitor AC fail, low voltage, etc. These
rectifier sensors trigger outputs that are monitored by the controller. The controller can trigger
output relays in the event of a rectifier alarm.
