Description
The Dalton U10-6K is a smart online UPS built for businesses that can’t afford downtime. Its double-conversion design regenerates clean, stable power all the time. Your equipment gets a pure sine wave output with ±1% voltage regulation, and switching to battery takes 0 ms, so devices never notice an outage.
- Wide input range and high efficiency
It handles input voltage from 110 to 288 VAC and frequency from 40 to 70 Hz, so it copes with weak or unstable mains without draining the batteries. The input power factor is ≥0.99, and efficiency reaches up to 94% in online mode and 96% in ECO mode, which keeps running costs low. - Built-in batteries, ready to install
The U10-6K includes 20 sealed maintenance-free batteries (240 VDC) inside the unit. That gives roughly 5–10 minutes of backup, depending on load, which is enough for a safe shutdown or until a generator starts. For longer backup times, choose the U10-6KS model, which connects to external battery banks. - Smart monitoring and control
An LCD and LED display shows the UPS status at a glance. USB and RS232 ports come standard, and optional SNMP, RS485 and dry-contact cards add remote monitoring. You can run up to 4 units in parallel for extra capacity or redundancy. An emergency power off (EPO) switch is on the rear panel.
Ideal for: server rooms, network and CCTV racks, banks, clinics, labs and offices that need continuous, clean power.
