Delta UPS V3 Battery Backup
The Delta UPS V3 is specifically designed for basement drainage systems (submersible pumps/sump pumps) when there is a loss of mains power. It will keep one Delta V3 Submersible Pump running during a power outage, keeping basements dry.
If power failure occurs, the Delta UPS V3 automatically powers the Delta V3 pump. It can provide power for 30 minutes continuously, based on a 3.5 m head. This is equivalent to 30 hours protection, in accordance with PCA guidance of a minimum of three activations
per hour.
A buzzer alerts the user when the pump is drawing power from the battery.
Simple to use and easy to install – the Delta UPS V3 clearly displays its status and comprehensive fault codes.
It is not suitable for powering a Delta V4 or Delta V6 pump. For such installations, please refer to the Delta UPS V4/6 or the Delta Battery Backup V4/6 range.
