SubDrive Duplex Alternator

Franklin Electric’s SubDrive Alternator allows a water system to alternate between two parallel pumps controlled by separate SubDrives. The user-selected switching interval balances the run time of each pump system to evenly disperse the workload. The SubDrive Duplex Alternator is ideal for applications requiring redundant systems. For high demand situations, the Alternator works on a lead-lag principle. When demand exceeds the capacity of one pumping system, the other comes online to supplement production. The NEMA 4 enclosure protects against rain, sleet, snow and external ice, water, dirt, and dust.

Features

• Ability to work with any two FE SubDrives or QuickPAKs
• Push-button design to select switching interval, 1 - 24 hours or manual
• Indicator lights to show time settings, status, and faults for each pump
• Safe operation using a 120VAC/12VAC outdoor rating and low voltage wiring connection
• Fail/safe design (system still produces water if Alternator is taken offline)
• Simple installation
• Fault detection
• Optional alarm contacts
