4. Introduction to the Regulator

Familiarize yourself with the various features and facilities by studying the two diagrams below to obtain maximum benefit from the regulator.

a. Front of the Regulator

500/1000VA model

The front panel features a digital display for input/output voltage, selection buttons for input/output voltage display, LED indicators, and a power switch.

b. Rear of the Regulator

500/1000VA model

The rear panel includes an output socket for connecting appliances, a circuit breaker, an AC input cable, and an output fuse.

5. Operation of the AVR

a. Connect the Electrical Appliances to Regulator

• Make sure all appliances are turned "OFF", and put power switch of AVR to "OFF" position.
• For model from 500VA to 1000VA, plug the AC mains cord of the appliances into the output socket of AVR, ensuring that the total starting power needed does not exceed the rated maximum output power of the AVR.

b. Connect Regulator to Electrical Mains

• For model from 500VA to 1000VA, just plug the AC mains cord to wall mains socket.

c. Switch on the regulator

Put the power switch to "ON" position. The yellow LED will illuminate and blink, indicating the delay time. The digital display will show the elapsing delay time (typically 6-180 seconds). After the delay, the yellow LED turns off and the green LED illuminates. The digital display will show the output voltage supplied to the connected appliances. Switch "ON" the appliances one by one.

In Case of Power Failure:

• Switch "OFF" the regulator and all the appliances.
• Repeat above steps when power is restored.

d. Display of Input Voltage and Output Voltage

• The output voltage will show in the display after switching it on.
• By pressing the "Input/Output Voltage Selective Button", the input voltage will be indicated in the display and flash.
• Press the "Input/Output Voltage Selective Button" again to show the output voltage.

e. LED Operation

• Green LED ON: Power ON, input and output voltage are normal, AVR is working.
• Yellow LED ON and flashing: Regulator is in delay status; output will be delayed.
• Red LED ON and flashing: Regulator is in protection status.

f. Delay Operation

This model is designed with a delay feature to protect appliances, especially those with compressors (like air-conditioners, refrigerators, motors, pumps, etc.), which should not be switched on immediately after being switched off. The delay time is typically set at 6 seconds. The delay time will show in the display after switching on the AVR. When the delay time has elapsed, the delay LED will switch "OFF" and the display will indicate the AC output voltage.

g. Integrated Automatic Protection Circuit (IAPC)

This model is equipped with a specially designed INTEGRATED AUTOMATIC PROTECTION CIRCUIT. This circuitry automatically cuts off the input voltage whenever the input voltage is above the input voltage range, rendering full and comprehensive protection to the regulator and connected appliances. When the input voltage returns to within the normal range, the IAPC will automatically switch the regulator back "ON" and restore power to all connected appliances.

h. Temperature Protection

This AVR is equipped with a unique TEMPERATURE PROTECTION CIRCUIT designed to protect the transformer, giving you longer and satisfactory use of the Regulator. If the internal temperature reaches the limit or above, the output will be cut "OFF" automatically, and the display will show "C". At the same time, the Red LED lights up. When the internal temperature returns to a normal range, output power will be restored. After the delay time, the display will indicate output voltage.

i. High Output Voltage Protection

This AVR has a built-in HIGH OUTPUT VOLTAGE PROTECTION CIRCUIT. This circuitry protects connected appliances whenever the output voltage is higher than the normal range. If the output voltage is over the normal range, the output power supply will cut "OFF" automatically and the display will show "H". At the same time, the Red LED lights up. Once the input city power returns to a normal range, the AVR will restore the output.

j. Low Output Voltage Protection

When the output voltage is below the normal range, the output will be cut "OFF" automatically and the display will show "L". At the same time, the Red LED lights up. Once the input city power returns to a normal range, the AVR will restore the output to the loads.

k. Short Circuit Protection

In case of a short circuit or overload, the POWER SWITCH (integrated with a resettable fuse function) or OUTPUT FUSE will trip off to cut off the input power supply. The OUTPUT FUSE should be replaced if it burns out. The Power Switch with the resettable fuse function must be reset to its initial position.
