5. APPLICATION
Automatic voltage regulator (AVR) is designed for providing various
equipment with high-quality stable electric power supply in conditions of
significant and continuous deviations of voltage and protecting your
equipment against high-voltage and pulsed interference.
6. MOUNTING
Important! Before mountint the regulator, make sure that all fixing
elements durable fastened to the wall!
• For securely wall mounting it is necessary to determine the type of wall material (wood, brick,
concrete, drywall, and etc.) for corresponding fastener selection.
• Mounting stabilizer location should be close to the wall outlet, considering the stabilizer power
cord length.
• Next, make a mounting fasteners (not included) to the wall, considering the wall mounting holes
location on the stabilizer rear panel (see Fig. 2).
• Then hang the stabilizer on fixing elements.

7. INSTALLATION
Attention! Before connecting the regulator, make sure that all consuming devices con-
nected to the regulator are switched off and the switch is in OFF position.
• Before installing the AVR, please make sure that total power of all consumers is lower than AVR
output power. Taking into account the starting loads and power factor of consumers, it is
necessary to apply power margin factor with the coefficient 1.2–1.5; but for such equipment as air
conditioners, fridges, etc., it should be 1.5–2.
Attention! When choosing an AVR, it is necessary to know that reduction of input voltage
increases an input current value, consequently, the maximum power of AVR is reduced
too! Such dependence is shown in the graph below:
Note. Adhere strictly to such dependence. If the condition stated above is not adhered to,
warranty servicing becomes void!
• Plug the stabilizer power cord in the wall outlet.
• Turn on stabilizer with switch (RESET position).
• If the AVR operates properly, green LED illuminates, and yellow LED will blink. At the same
time the digital indicator will show the input voltage. The total delay makes 6 or 180 s depending
on the "ЗАТРИМКА (Delaying)" button (Увімк./Вимк. (ON/ OFF)) position. After the delay time
yellow LED turns offand digital indicator will show the output voltage of the regulator. And only
after that you can turn on the connected devices, consumers.
• When the mains voltage exceeds the allowable rate (lower threshold is 140 V, upper threshold is
260 V) the red LED illuminates, the AVR disconnects the load automatically.
Attention! It is recommended to switch off the AVR and every connected consumer device
when the power supply is dropped.

Operation Manual
STAB SLIM
Attention! If the AVR is not used for a long time, it is recommended to disconnect the AVR
and all consumer devices from the power supply network.
1. The switch is off.
2. There is no power in the
socket.
3. The AVR power switch 
has activated.
The AVR is out of order.
Input voltage is very unstable.
Input voltage is beyond
possible regulation range of
140 – 260 V.
8. PAUSE FUNCTION
• The Pause mode feature is designed to protect equipment in case of frequent drops of the mains
supply. This is particularly important for consumer appliances with electric motors or compressors.
After power supply has been recovered, the AVR switches on within 6 or 180 seconds, depending
on the "ЗАТРИМКА (Delaying)" button (Увімк./Вимк. (ON/ OFF)) position.
9. PROTECTION FUNCTION AGAINST HIGH AND LOW INPUT VOLTAGE, OVERLOAD AND
OVERHEAT
• The stabilizer is equipped with an circuit overvoltage and undervoltage protection. In the case of
mains voltage deviation over 260 V or below 140 V it turns offthe load automatically. At the same
time red LED illuminates. When the input voltage range returning to 140-260 V the stabilizer
automatically resumes operation.
• In case of overload or short-circuit AVR power switch will triggered. After elimination overload
cause or short circuits, press AVR power switch (RESET position), and stabilizer will resume
operation.
10. TROUBLESHOOTING
If none of the above methods can solve the problem, please seek professional advice at your
nearest service center. Never attempt to repair the product yourself.
1. Press the switch once again.
2. Make sure there is electric
power supply.
3. Disconnect part of the load
and switch on the AVR again.
If the fault is not eliminated,
please address to an authorized
service center.
The AVR is regulating output
voltage.
When input voltage is normalized,
the AVR tuns on automatically.
The AVR does not start.
The AVR is in operation mode,
but there is no output voltage.
The AVR often produces
clicking sound.
The AVR has disconnected
the load.
