USER’S MANUAL
AUTOMATIC VOLTAGE REGULATOR
Model: AVR-REL-500/1000/1500/2000VA-WL
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 2000VA, 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 2000VA, just plug the AC mains cord to wall mains socket.
c. Switch on the regulator, Switch the power "ON"
• Put the power switch to "ON" position, the yellow LED will illuminate and blink . At the same time, the digital
display will show the elapsing delay time. Generally delay time is set at 6~10 seconds.
• Then the yellow LED lights off and the green will illuminate.
• The digital display will show output voltage supplying to appliances connected to the regulator.
• 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 switch 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
• When the Green LED is "ON", it indicates Power ON and also that the input voltage and output voltage is
normal, the AVR is working.
• When the Yellow LED is “ON” and flash, it indicates that the regulator is in a delay status, the output will be
delayed.
• When the Red LED is "ON" and flash, it indicates the regulator is in a protection status.
f. Delay Operation
• This model is designed with a delay feature to protect appliances especially the appliances with
compressors(like air-conditioner, fridge, motor, pump,and etc). which should not be switched on immediately
after being switched off.
• The delay time is generally set at 6/180 seconds selectable.
Select delay or undelay before switch on the
AVR.
• Press down the delay button, then you select the delay, the delay time will be 180 seconds. After switch on the
AVR, wait for 180 seconds, then the AVR delivers output; Press up the delay, it means undelay, under "undelay"
status, the delay time is 6 seconds.
If you connect the appliances with compressors, we suggest that you select "delay" before
switch on the AVR.
• The delay time will show in the display after switch on the AVR. When delay time has elapsed, delay LED will
switch "OFF" and display will indicate the AC output voltage.
