•
Its primary function is the power supply for household and industrial equipment, which is
critical 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
enables 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 different
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 capacity 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 required
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 capacity (if
their capacities are different, the batteries will have different internal resistance and due to this the
charge level will be different).
•
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 connected similarly. The connecting
cables must have a sufficient cross-section and a minimum length.
