The Delta UPS V4/6 is specifically designed for basement drainage systems (submersible pumps/sump pumps) when there is a loss of mains power. It will power one Delta V3, Delta V4, or Delta V6 Submersible Pump during a power outage, keeping basements dry.

If power failure occurs, the Delta UPS V4/6 automatically powers the pump. It can provide power to a Delta V6 pump 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 V4/6 clearly displays its status and comprehensive fault codes.
