Riello Galatrek Intros New Dialog Dual UPS

Riello Galatrek Ltd. (UK), a subsidiary of Riello UPS Manufacturing (UK), introduced the new Dialog Dual uninterruptible power system (UPS), which designed to protect critical computer, telecom and security applications from mains failures and power fluctuations. The new Dialog Dual 3.3kVA and 4kVA UPS offer a host of features to enhance their installation, electrical performance and communications capabilities in critical applications.

The Dialog Dual can be installed as either a slim-tower format UPS sitting beside a file server or phone switch or as a 19in rack-mount system in a standard 600mm deep cabinet to save floor space. The Dialog Dual features a backlit, multi-function, easy-to-read display that can be turned 90° when installed into a 19in rack-mount cabinet. The LCD provides a host of information on the general running state of the UPS, including input and output voltage and frequency, internal UPS temperature, load and battery percentage, and battery run time available.

In addition, the Dialog Dual has been designed to minimize its battery usage. The UPS can provide a stable sine wave inverter output down to as low as 140Vac, and can ride through mains breaks of up to 40mS in duration – with batteries. A rear-panel battery extension pack connector is standard to allow the 10-minute run time to be extended to over eight hours. An automatic overload/system alarm bypass is standard to protect the UPS should it suddenly overload. The five user-selectable sine wave operating modes can be selected from the front panel to achieve up to 98% operating efficiency. They include on-line, line interactive, smart-active, frequency conversion, and standby for

emergency lighting applications.
