USER’S MANUAL
AUTOMATIC VOLTAGE REGULATOR
Model:
AVR-SRV-XTREME500/1000/3000/5000/10000-WL
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.
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.
K. Short Circuit Protection
In case of a short circuit or overload, the circuit breaker will trip off to cut out the power supply.
• Check if the AVR is overloaded. If so, please remove some loads.
• Check if the appliances are short circuit. If so, please disconnect them.
