The PowerMaxx2 is a battery back up unit specifically designed for pump applications to ensure they can still operate should there be a power outage.
Overview
- It can run 2 x V3 ground water pumps (not simultaneously) without mains power for up to 15 days depending on the number of cycles per day.
- 1 or 2 pumps are directly fed through the PowerMaxx2.
- If a power failure occurs, the duty pump will draw power from the PowerMaxx2 which will have been fully charged during normal operation.
- The unit will automatically recharge when mains power returns and incorporates a compact quick charger to top up the battery from empty in just 25 hours.
- Dynamic Polling (DyPol) enables the PowerMaxx2 to achieve extended backup times by dynamically requesting if the equipment requires backup power and alternating between a state of hibernation, request and supply.
- The digital display shows status and comprehensive fault codes, whilst the internal log captures and records critical events.
- The user menu function allows you to locally reset the battery life indicator.
- The PowerMaxx2 can operate as a stand alone unit or can be used in conjunction with an AlertMaxx2.
- Data from the Hi-PowerMaxx2 can be shared with the AlertMaxx2 when connected to Wi-Fi.
