3. SAFETY PRECAUTIONS
• When the input voltage is higher than 290V, failure of the AVR is possible.
• Do not operate the AVR in the environment with temperatures other than indicated in Technical
Specifications.
• The case heats up in operation. Operate the AVR in the environment with good air convection
only.

z Connection of electric heating devices is forbidden.
* For models with built-in power cord with plug.
4. TECHNICAL DESCRIPTION
Automatic Voltage Regulators (AVR) are designed to protect your electronic equipment from
unstable mains voltage. Over- and undervoltage and pulse interference prevents electronic
equipment from normal operation and can easily damage it. AVR is designed to protect all types of
TVs, DVD players/recorders, refrigerators, audio and PC equipment and other home electronic
appliances. Its operating principle is based on discrete regulation of input voltage range. AVRs
provide standard power supply to connected load witnin the range of ~230V (-14/+10%) with input
voltage fluctuation within ~140-275 V + 3%. The built-in surge protector provides protection from
pulse interference.
Special features
• Microprocessor control
• Enhanced precision of output voltage regulation
• Protection of consuming appliance against high/low voltage
• Protection of AVR against short circuit and overload
• Thermal protection of autotransformer
• Power supply delay function (6 - 180 sec.) after work resumption
• Digital indicator of input/output voltage on the front panel
• Built-in surge protector
Caution! High voltage inside! To avoid the risk of electric
shock do not open or touch elements inside.

5. INSTALLATION AND OPERATION GUIDE
Attention! Before connecting the regulator, make sure that all consuming devices connected
to it are off, and stabilizer switch g is set to «OFF» position.

ENG

Attention! When choosing an AVR, it is necessary to consider that reduction of input
voltage increases value of input current, which means that maximum power of AVR is
reduced too! Such dependence is shown in the graph (Fig.7).
Note. Keep in mind this correlation. If the condition stated above is not met, warranty
servicing becomes void!
• Before installing the AVR, please make sure that total starting current of all power consumers
is lower than AVR power. Besides, taking into account the starting load and power factor of
consumers, it is necessary to apply power margin factor of 1.2–1.5; for such equipment as air
conditioners, fridges, etc., it should be 1.5–2.
• Connect the equipment to the power outlet (s) of the stabilizer.
• Connect the AVR to the power network of 230 V.
Attention! Do not connect the regulator (VR-A3000, VR-A5000, VR-A8000, VR-A10000) to
a household outlet. Maximum current circuit breakers should not be less than the current
circuit breaker on the front panel of the product.
• Press button g. When the stabilizer turns on green LED «Working» gets activated. The digital LED
display b starts the countdown to actual issue of connected power load, while the red LED
«Protecting» blinks. You can choose delay time of powerload issue by pressing Delay button f on
the front panel. After the pause output voltage value is indicated on the LED display b. By
pressing the «I / O» button select indication of the display input or output voltage to be displayed.
Input voltage is displayed via blinking indication.
• When AVR ups or downs voltage, the input voltage indicator will glow with yellow LED
«Regulating».
• In case of overload or short circuit the thermal fuse is triggered. After fixing the cause of overload
turn on the stabilizer (for low-end models, including protective fuse, pressing the button j on the
rear panel).
• When the stabilizer input voltage is higher than 275 V or below 140 V ± 3% the regulator
disconnects the load. At the same time LED operation indicator displays «H»/«L» sign (high / low
input voltage). On the front panel «Protecting» indicator d lights up.
• In models with forced cooling, fan operates at a temperature of autotransformer around 65 °C.

Problem
The stabilizer does not
work.
Stabilizer turned on.
Indicator «Protecting»
doesn't turn off and there
is no output voltage.
Stabilizer disabled load.
«Protecting» indicator
active. The display shows
«L» or «H».
Stabilizer disabled load.
On the LED displayed
«C».
The stabilizer keeps
clicking. «Regulating»
indicator active.
Cause
1. Switch is not turned on.
2. There is no voltage in the mains
socket.
3. Too much load connected.
Protection fuse triggered.
Failure of the testing scheme.
The AVR is defective.
Input voltage is too high or too
low.
Overheating of the transformer.
The stabilizer is overloaded.
The input voltage is very unstable.
Solution
1. Turn on the stabilizer.
2. Make sure the input voltage
is available.
3. Disconnect part of the load.
Turn on the protective fuse.
Switch the AVR off and on again. If
the problem persists, address a
service center.
When the input voltage reaches
140-275 V ± 3%, the AVR will
resume its operation.
Turn off the AVR. Disconnect part of
the load. After cooling down turn on
the stabilizer.
It is normal. The AVR is regulating
the output voltage.
6. TROUBLESHOOTING
If none of the above can solve the problem, please seek professional advice at your nearest service
center. Never attempt to repair the product yourself.
