OPTI-UPS Durable Series DS1500B 1500VA 1050W True Online, Double-Conversion, High Frequency Pure Sinewave UPS with AVR & Zero Transfer Time

Truly Uninterruptible Power

The Cold Start (DC Power On) function allows the UPS to instantly start in the absence of AC grid power. Moreover, the current flow is absolutely uninterruptible, because the transfer time is zero.

Double-conversion Design

A double-conversion refers to converting the incoming AC power into DC power, and inverting it back to AC power. This ensures the newly reproduced power to be of a quality standard set by UPS, to be completely cleared of all imperfections of the power coming from the AC mains. Regardless of what is going on the AC mains side, the UPS output voltage, frequency and signal purity are kept up to the highest standards.

Data Line Surge Protection

RJ11 / RJ45 surge-protected ports safeguard your connected equipment from damaging surges and spikes that travel along utility and phone lines.

Hot-swappable, Replaceable Battery

The built-in high-quality rechargeable battery lets the UPS run for 18 minutes at half load (6 minutes at full load)*, so you have time to save files and protect data. The replaceable battery is hot swappable, thus enabling continuous operation even when battery is being replaced. With extended battery connectors, this UPS also supports up to two external battery packs (not included) for a longer backup time.

Note: * Battery backup time varies depending on models.

Intelligent-ready Networking

In addition to a USB communication port, the DS1500B features a RS232 port and a Web/SNMP communications card slot*. This means users can easily connect it to networked computers, and manage the UPS remotely across the network.

Note:* This model provides both RS232 and USB connectivity, but only one connectivity can be used at a time. SNMP card required, sold separately.

Built-in Intelligent Fan

With its smart fan speed control, the built-in intelligent fan is able to automatically change rotation speed depending on system requirements, to decrease power consumption and noise.

User-friendly Design

The LCD front display provides visual notification of the UPS status, while the audible alarms actively inform you whether the unit runs correctly, the battery is low, or if there is an overload condition. You'll also appreciate the EPO port, an emergency power off switch.
