• It is strongly forbidden to open the cover of the device, there is high voltage inside. If some problems occur, please read the operation manual carefully and address an authorized service center.
For the list of authorized service centers please go to www.real-el.com.
• Do not let liquid get inside the device, it can cause short circuit or electric shock.
• In case there are signs of improper operation of the device (sparkling, unusual smells, etc.),
unplug the device from the mains immediately and address your nearest authorized service center.
• It is forbidden to connect the automatic voltage regulator to devices with power consumption
higher than its maximum output power. It can cause breakdown of the device.
• Do not let children operate the device.
It is strongly forbidden to operate the device in the following conditions:
– in dusty environment or environment containing highly inflammable gas;
– at temperature higher than 40 °C or lower than 0 °C;
– at humidity level higher than 90 %;
– in direct sunlight or next to heating elements;
– in vibration areas;
– outdoors.
• In case of fire use only powder fire extinguisher, as water can cause electric shock.
• The automatic voltage regulator should be installed in proximity to power supply, then it will be
easier to unplug the device if necessary.
Caution! There is high voltage inside on unsolated components,
which can result in electric shock.

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
Fig. 3. Side panel
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 connected 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:
Output power, %
100
75
50
25
100 110 12 0 13 0
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 off and 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.
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.
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 off the 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
CauseProblemSolution
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.
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.
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.
