EXELTECH manufactures the world's first truly redundant, modular inverter system; the most reliable inverter system available. No single malfunction will cause the inverter system to fail. Modules are "hot" insertable ( except for 12vdc). Power levels are expandable, and modules can be added or replaced without interruption in power to your critical loads. The Exeltech MX series inverters are true sine wave, very versatile, custom inverters designed for use where reliability and high power quality is extremely important. MX systems can be configured with power levels from 1000 watts to 20kW at 120Vac output, to 40kW at 240Vac bi-phase, or to 60kW at 208Vac 3 phase. Power levels are expandable, and inverter modules can be upgraded or replaced, and if designed as a redundant system, a replacement can occur while the system is on line without interruption in power to your loads. The output voltage is precisely regulated, so that no measurable voltage change occurs on the output when the input voltage changes over its wide voltage range. Less than 0.5 volt change in output will occur when the output load varies from 0 to 100% of rated power. With distortion of 2% maximum, this offers the cleanest sine wave power available. The system is extremely compact and lightweight. Modules, cards and cages are combined to create the inverter needed. A Master Module combines the control signals of a Control Card with a Power Module. This is a space saving solution when redundancy is not necessary. The Master Module provides control signals to up to 19 power modules. The Power Module is a 1000 watt slave power inverter. It requires drive signals from a Master Module or a Control Card. This module is the backbone of the inverter system and will be the majority of the modules in most systems. The Control Card provides all the control functions fro the Power Modules. Adding a second Control Card provides redundant operation as only one Control Card is required to operate the system. The Alarm Card is necessary in a redundant system. It allows the inverter to detect a Control Card failure and switch to the backup Control Card. The Alarm card provides LED indicators for DC on, inverter on, load presence, inverter fail, breaker open, high temperature, and low voltage and "form-C" contact closures for minor failure, major failure, inverter failure, bypass, DC failure and AC failure. The Transfer Switch allows the inverter to automatically switch between inverter power and a secondary source of AC power. The transfer has a maximum capacity of 50 amps and a typical transfer time of 4ms. Determine the components to order below. For 120/240v operation, order twice as many Master Modules or Control Cards and Cages. For 3-Phase order 3 times as many Master Modules or Control Cards and Cages.
