PRESENTATION
This manual describes the Dialog Vision UPS family (DVT, DVR, DVD) and their related battery box.
The Dialog Vision is a line-interactive UPS.
The UPS protects equipment connected to it from:
a) mains power supply failures
b) surges
c) sags and brownouts
The UPS automatically corrects its output for small fluctuations in the mains power supply. In the event of larger
fluctuations or a complete mains power supply failure, its output is powered from the inverter drawing energy
from the internal battery set
The UPS can operate from a mains power supply even if there is no battery available. In this instance all other
functions (AVR, start-up or shutdown and overload protection) are available.
CHARACTERISTICS
 Sinusoidal output voltage
 Front panel LCD
 Microprocessor control for high reliability
 High frequency technology
 Automatic correction of input voltage fluctuations by the built-in Automatic Voltage Regulator (AVR). The
AVR, compensates for input voltage variations within a defined input voltage window and maintains a
stable output, without resorting to batteries. Using the batteries less frequently ensures that they are at full
capacity when they are actually needed and helps them to last longer.
 Selectable output range
 Cold start
 Integrated volt-free contacts/RS-232/USB port
 Back-up time can be increased by adding a battery box (DVD 220/300 models only)
 Overload, short-circuit and overheating protection
 Configurable as Rack or Tower (DVD models only)
 Models DVR and DVD suitable for installation in 19” rack cabinets
