USER’S MANUAL
AUTOMATIC VOLTAGE REGULATOR
Model: AVR-REL-POWERUP500/1000-WL
AUTOMATIC PROTECTION CIRCUIT.
•
This very specialized and unique circuitry is now redesigned to automatically cut 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 Low and Normal ranges, the IAPC will automatically switch the
regulator back "ON" and also restore power to all connected appliances.
I. High Output Voltage Protection
•
This AVR is built in with a very specialized feature HIGH OUTPUT VOLTAGE PROTECTION CIRCUIT.
•
This special and unique circuitry is designed to protect 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 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 normal range, the AVR will restore the output to the loads.
6. Placement
For safety and better performance and longer lifespan, please handle and place the AVR according to the follow
instructions:
a. Moving
a. Cut off input; remove all wires connected to the AVR
b. Do not move the AVR upside down
c. Rough handling is prohibited
b. Environmental
Keep away from unstable base or sources of excessive vibration.
Do not place the AVR under direct sunlight or excessive humidity.
Keep away from fire, heat sources.
Keep the AVR in well ventilated place. Leave at least a distance of 10 cm between the AVR and the walls in
order to maintain adequate air-flow.
Operating Temperature: -10
˚
C~40
˚
C
Operating Humidity: 0~90% (Non-condensing)
Keep away from corrosive gas or fluid.
5
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 normal range, output power will be restored. After the delay time, the
display will indicate output voltage.
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 of the input power supply. The OUTPUT FUSE
should be replaced in case if will burn out.
The Power Switch with the resettable fuse function must be resettled
on the initial position.
•
Check if the AVR is overloaded, if so, please remove some loads.
•
Check if the appliances are short circuit, if so, please disconnect the appliances.
