Manufacturer and distributor Exeltech Inverters.

Exeltech, Manufacturer Distributor of Sine Wave Power Inverters, Battery Chargers, Rectifiers and Accessories, N+1 Redundant, Expandable, Remote Switching, True Sine Wave, "HOT" Insertable, 1000 Watt Modules, Remote Metering, Adjustable Power.

The Exeltech MX Series of inverters is a modular system which 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. Options such as AC distribution, AC disconnect, metering, DC disconnect, DC distribution, transfer switch and maintenance bypass switch are also available; (see accessories).

The building blocks of the system are as follows:
 

• Information on PDF

1.) Power Module - 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.

2.) Master Module - A 1000 Watt power inverter which contains all the electronics necessary to operate. Requires an enclosure to provide connections to the battery and AC output. It can also operate up to 19 slave Power Modules. If this module is used, the system cannot be fully redundant. All MX systems require either a master module or at least one control card.

3.) Control Card - Generates 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 a completely redundant inverter system. All MX systems require either a master module or at least one control card.

4.) Alarm Card - Can be used in conjunction with a redundant or non redundant inverter to provide various alarm output signals via LED's and alarm contact closures. Must be included in redundant systems to detect failure of control card.

5.) Transfer Switch - Provides 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 of 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 - Compatible with a 19" relay rack. The smallest cage which can contain a redundant system. Available in the following configurations:

19A - Basic configuration for a redundant system. Holds up to 4 Power Modules, 2 Control Cards and either a Transfer Switch or an Alarm Card.

19B - Used as an expansion rack or may be used as an expandable, non redundant inverter, up to 5 KW. This configuration will not accept X-fer Switch, alarm card or control cards.

2.) 23" cage assembly - Compatible with a 23" relay rack.

23A - Basic configuration for a redundant system. Holds up to 5 Power Modules, 2 Control Cards and either a Transfer Switch or an Alarm Card.

23B - 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.

7C - Consists of 1 Transfer Switch and 1 Master Module. This configuration will not accept an alarm card or control cards.

7B - Expandable up to 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 1-3KW systems when redundancy is not required.

9C - Consists of Transfer Switch, 1 Master Module and 1 Power Module. This configuration will not accept an alarm card or control cards.

9B - Expandable up to 3KW. 1 Master Module and 2 Power Modules. This configuration will not accept X-fer Switch, alarm card or control cards.

The Exeltech MX Series of inverters is available in three basic architectures; redundant, upgradable and expandable. Different options and sizes are available to fit varying applications. As a benefit of the MX series modular design, power levels are expandable in any system, as power requirements increase.

1.) N+1 Redundant-Expandable Inverter System: For applications where reliability and maintainability are paramount, the N+1 redundant system offers the most cost effective method of achieving redundancy and the ability to maintain the system while loads remain on line. All cards (except 12 Vdc) are "hot" insertable to allow maintenance without interrupting power to critical loads. Designing the power level with N+1 number of power modules, allows for redundancy without necessitating the purchase of a duplicate system. (An A/B Buss option is available, which adds to system reliability).

2.) Upgradable Inverter System: The Upgradable system offers the flexibility to add a X-fer switch or alarm card and Full Redundancy for future requirements. A minimum system with as little as one control card and one power module can be upgraded in the future to include additional power modules, X-fer switch or alarm card and an additional control card for full redundancy (see figure II).

3.) Expandable inverter system: This configuration can be used as an independent inverter system (figure III), or to expand power levels of existing MX systems (see stacked systems). By using one master module, a system may be expanded to include a X-fer switch and additional power modules(see figure IV). 1KW inverters with a X-fer switch use the 7"or 9" (part # 7C, 9C) cage. 1KW, 2KW and 3KW inverters without a X-fer switch use the 7" or 9" (part number 7B, 9B) cage assembly.
