4. TECHNICAL DESCRIPTION
Operating principle
• Models of SVEN RТ are designed to operate with lead-acid maintenance-free 12 V batteries
ofAGM type.
• Models of RТ series fall in the line-interactive uninterruptible power supply of continuous ac-
tion with prolonged back-up time. Principle of their operation is based on the transformation
of direct current of external batteries to alternating current. Current waveform at the output
isthe regular sinusoidal wave.
• Its primary function is the power supply for household and industrial equipment, which iscrit-
ical to the input current waveform (boiler equipment, automation systems with equipment
withprogram control (servers, databases, etc.) with medical equipment).
• The device is equipped with the automatic voltage regulator (AVR). The built-in regulator en-
ables to provide correct power supply at overvoltage/undervoltage of the mains without going
to the battery operation mode.
• The automatic start function provides automatic switching on when there is power supply.
With input voltages 160 V or less, as well as 260 V or more the automatic start is not activated.

• The three-stage switch of charging current enables the user to connect batteries of dierent
capacities depending on the required time to provide the power backup. It is recommended
forthebattery with the capacity 20–50 А·h to use the position L (3–5 A) of the switch, withtheca-
pacity 50–100А·h touse the position M (7–9 A), with the capacity 100–200 А·h to use the position
Н (13–15 A).
Recommendations regarding selection of batteries
• Select the capacity of a battery (batteries) depending on the connected load power and re-
quired time of power standby, see the table 1 below. Based on the selected capacity, choose
acertain battery (batteries).
• Storage conditions of batteries must conform to the requirements of the battery producer.

• We recommend to use SVEN SV12170, SVEN SV12500, SVEN SV121000 batteries.
Notes. When two or more batteries are used, they should be of one type and have the same capac-
ity (if their capacities are dierent, the batteries will have dierent internal resistance and due
to this the charge level will be dierent). Batteries should be connected in parallel, when several
batteries are used simultaneously. Additional cables (to be purchased separately) will be required
to connect extra batteries. When two or more batteries areconnected, theplus terminal of one
battery is connected to the plus terminal of the other battery, minus terminals of batteries are con-
nected similarly. The connecting cables must have a sucient cross-section and a minimum length.
