The MX Series
of inverters is a highly modular system of products that can
be assembled in many combinations to afford the user infinite
flexibility. All MX systems feature manual power
adjustment allowing power modules not in use to be turned off,
reducing "no load" current drain. Optional remote
metering and switch is also available.
The building blocks of the system
are as follows:
1. Power Module - This
is a 1000 Watt slave power inverter. It requires drive signals
from a Master Module or Control Card as described below. This
module is the backbone of the inverter system and will be
the majority of the modules in most systems.
2. Master Module -
This is a 1000 Watt power inverter that contains all the electronics
necessary to operate. It requires an enclosure to provide
connections to the batter and AC output. This module can also
operate up to 19 slave Power Modules as listed above. If this
module is used to operate the slave modules the system cannot
be fully redundant.
All MX systems require
either a mater module or at least one control card.
3. Control Card - This
card will generate all the signals necessary to operate up
to 20 Power Modules. The card itself will not generate any
AC output power nor does any power flow through it. This card
can be paralleled with another Control card to generate a
redundant set of control signals to form the basis of completely
redundant inverter system.
All MX systems require
either a master module or at least one control card.
4. Alarm Card - This
card can be used in conjunction with a redundant or non-redundant
inverter to provide various alarm output signals to the user
via LED's and alarm contact closures. It must be included
in redundant system to detect failure of control card.
5. Transfer Switch
- Provides all the same functions as the alarm card, plus
provides a relay to transfer AC power to the load from either
the inverter or the utility input. Use only with systems 7KW
or less.
The above modules can be placed
in the following enclosures. Installations can either be free
standing or in standard relay racks.
1. 19" cage assembly
- This enclosure is compatible with a 19" relay rack.
This is the smallest cage that can contain a redundant system.
It is available in the following configuration:
A. This is the basic configuration
for a redundant system. It can hold up to 4 Power Modules,
2 Control Cards and either a Transfer Switch or an Alarm
Card.
B. This uses as an expansion
rack or may be used as an expandable, non-redundant inverter,
up to 5KW. This configuration will not accept X-fer
switch, alarm card or control cards.
2. 23" cage assembly
- This enclosure is compatible with a 23" relay rack.
A. This is the basic configuration
for a redundant system. It can hold up to 5 Power Modules,
2 Control Cards and either a Transfer Switch or an Alarm
Card.
B. This is used as an
expansion rack or may be used as an expandable, non-redundant
inverter, up to 6 KW. This configuration will not
accept X-fer switch, alarm card or control cards.
3. 7" cage assembly
- For 1 or 2KW systems when redundancy is not required.
A. This configuration
consists of 1 Transfer Switch and 1 Master Module.
B. This configuration
is expandable up 2KW. 1 Master Module and 1 Power Module.
This configuration will not accept X-fer switch,
alarm card or control cards.
4. 9" cage assembly
- For 1-eKW systems when redundancy is not required.
