IMPORTANT SAFEGUARDS

This manual contains important safety instruction that should be followed during the installation and maintenance of the AVR. Please read this manual thoroughly before attempting to install or operate in this AVR.

1. Read all instructions carefully.
2. This equipment is available for 220Va.c. supply voltage and loads. Please verify that this model matches your AC main /load voltage requirements.
3. This equipment is designed for normal use only. The manufacturer neither recommends nor knowingly sells this product for use in critical life support application. Connect if possible to main supply socket outlet with an earth connector. A means of disconnection of the main supply should be within 2 meters of the AVR.
4. The AVR relies on your building wiring over-current protection, which must be rated between 30 amperes.
5. This unit is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliances by a person responsible for their safety.

6. Children should be supervised to ensure that they do not play with the AVR.

7. Although your AVR has been designed and manufactured to assure personal safety, improper use can result in electrical shock of fire. To insure safety, please observe the following rules:

8. Turn off and unplug your AVR before cleaning. Do not use liquid or aerosol cleaners. A dry cloth is recommended to remove dust from the surface of your AVR.

9. Do not install or operate your AVR near water.
10. Do not place the AVR on an unstable cart, stand or table.
11. Do not place the AVR under direct sunlight or close to heat emitting sources.
12. Do not place the AVR power cord in any area where it may get damaged by heavy objects.
13. Do not overload or short circuit the AVR.
14. Follow all warnings and instructions marked on the AVR.
15. When connected to any appliance with the built-in motor compressor, the starting power is generally several times of the appliances listed power rating. Make sure that the total starting power capacity of all connected appliance does not exceed the listed maximum output power capacity of the regulator. For color TV, calculate it twice as its listed capacity.
16. Make sure that the regulator is of the same output voltage and frequency as the appliance's it connected.
17. Make sure that the voltage of electrical source is within the listed range of input voltage of the regulator.

8. ATTENTION:

Turn off and unplug the your AVR from the convenience outlet and contact or bring the AVR to Imarflex Authorized Service Center if;

• The power cord or plug damaged.
• Liquid has been spilled on the AVR or it emits a strange smell from inside.
• The fuse blows frequently or the circuit breaker trips frequently.

• The AVR does not operate even when user follows the operating instruction.

• Save this instruction manual for reference.

INTRODUCTION

When choosing an AVR it is necessary take into account the power of the equipment which is to be connected to the unit (further referred to as the load). We recommend selecting an AVR capacity being 20%-30% higher than the estimated power of the load. In case of connection of electrical motors (an asynchronous motor, compressors, pumps, etc.), it would be necessary to consider high starting currents, and select capacity of the AVR 2.5 to 4 times higher than the power of the load.

NOTE:

BE SURE TO CONNECT THE PLUG INTO THE CONVENIENCE OUTLET PROPERLY. OPERATE THE REGULATOR IN THE RANGE OF RATED INPUT VOLTAGE ONLY.

CAUTION

Avoid overloading. Do not use the regulator beyond its maximum power

The AVR has an overload protection, the regulator will automatically turns OFF once the power exceed on its maximum power capacity. Remove the load/appliance plugged on the AVR and wait for at least 5 minutes. The AVR will turn ON again once the temperature of the motor/transformer decrease.

INSTALLATION

Inspection

Inspect the AVR upon receipt. The packaging is recyclable. Save it for reuse or dispose of it properly.

Placement

Install the AVR in a secure area with adequate airflow, and away from direct sunlight and excessive dust.

Connecting

Connect the AC input power plug into the convenience outlet.

Follow the steps below:

1. Make sure that the AVR do not have any mechanical damages.
2. If necessary, perform grounding of the casing of the AVR by connecting the grounding wire to the corresponding terminal, or at least make sure that the main outlet is grounded and available with 2 or 3 pins connection.
3. Plug the AVR to 220Va.c convenience outlet.
4. Select the proper delay time, default selection is 6 seconds.
5. Switch on the AVR and read the voltage meter LED display if it has output.
6. Switch OFF the AVR every after use.

Connecting the Loads

Plug the load into the output sockets of the AVR. Switch ON the AVR and then turn ON the load.

INDICATORS

LED Display

Display the input and output voltage values.

LED

Green LED "Power

Indicate that the power is ON and the convenience outlet where the AVR is plugged in is working.

Yellow LED "Delay"

When the delay time is selected, this light indicator will blink continuously until the selected delay time is finished, or upon the restoration of the main voltage. During delay time, the AVR has no output voltage. It will automatically turn off once delay time is finished.

Red LED "Protection"

Indicating the AVR is executing protection: the load exceeds to its maximum power capacity, low and high voltage protection activated.

PERFORMANCE

Automatic Voltage Regulator

Automatically regulate the input voltage to a more stable level for your appliances to avoid damages to the appliances.

Microprocessor Control

By means of innovative software control programs, the complicated hardware circuitry is inlaid in the powerful microprocessor. Apart from reduced size, it also lowers the defective rate of AVR and the accuracy in the regulations.

Voltage Display

Through an analogue meter or an LED meter, shows the input or output voltage of the device.

Delay Time

Upon switching on or resuming from the protection, the AVR will wait 6 seconds or 180 seconds (selectable) before it give output voltage, this time is called DELAY TIME, the delay function is designed to avoid the transfer to load of surges and spikes and distortions of sine wave voltage occurring upon the switching of the device. The default delay time is 6 seconds. We recommend a 180 seconds delay time selection where the unit is designated for the protection of a motor based appliance.

Surge and Spike Protection

Protect the hardware from damage.

Operation Principle

The CPU based intelligent circuit samples the input voltage and controls the action of the delays and opening of the tap of the transformer in a proper combination to adjust the output voltage. The output adjusting is performed based on the following algorithm:

• If the mains voltage stays within the range of 140±5Va.c to 260±5Va.c, then the output voltage being regulated to 220Va.c±8%.
• If the main voltage drops below 140Va.c, then the output voltage equals to the main voltage increases by 30% until it reaches the value of 180Va.c±5 which is the down threshold of the AVR. If the output voltage drops below than 180Va.c±5, the output will complete cut off.
• If the main voltage rises above 260Va.c, then the output voltage equals to the main voltage decreases by 10% until it reaches the value of 255Va.c±5, which is the upper threshold of the AVR. If the output voltage exceeds 255Va.c±5, the output will complete cut off.

The loading capability of the AVR varies from the input voltage;

- If the main voltage stays within the range of 200Va.c±5 to 260Va.c, then the AVR performs a maximum loading capacity to its rated level.

- If the main voltage drops below 200Va.c or exceed 260Va.c, then the loading capacity of the AVR drops accordingly to the input voltage dropping or exceeding percentage.

- If the main voltage stays within the range of 200Va.c±5 to 260Va.c, then the AVR performs a maximum loading capacity to its rated level. - If the main voltage drops below 200Va.c or exceed 260Va.c, then the loading capacity of the AVR drops accordingly to the input voltage dropping or exceeding percentage.

TROUBLE SHOOTING
PROBLEM	POSSIBLE CAUSE	REMEDY
AVR switch off but the power supply is operating	-The load exceed to AVR maximum capacity-Low and High Input Voltage Protection Activated	-Check the load power. Unplugged the load from the AVR, wait for at least 5 minutes.
	-Input Voltage exceed to AVR voltage range capacity.-Circuit Breaker of the AVR activated.	Switch off the load. Unplug the AVR. Check the Voltage supply. Plug the AVR on the outlet that is in the voltage range of the AVR. Plug the AVR and press the reset button. Switch on the AVR.
