Exeltech MX 66v Control Card generates the AC voltage and frequency reference necessary to operate up to 20 Power Modules in phase 1 at 66v DC input.
All MX systems require either a master module or at least one control card.
- Control Card Phase 1 – Generates the AC voltage and frequency reference necessary to operate up to 20 Power Modules in phase 1. 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 reference signals to form the basis of a completely redundant inverter system.
- Control Card Slave Phase – The control cards in phase 2 or phase 3 of a multi-phase system set the AC voltage of their given phase but have no control over the frequency or phase angle relationship with phase 1. Slave phase control cards are designated in the part number by the addition of the “-01” option code.
