3. Setup

3.1 Placement

• Place the ATVR-500 on a stable, flat surface.
• Ensure adequate space around the unit for proper ventilation. Do not block the heat dissipation holes on the sides and rear.
• Avoid placing the unit in direct sunlight, near heat sources, or in areas with high humidity or dust.

3.2 Connecting the Regulator

1. Input Power: Connect the ATVR-500's integrated power cord to a suitable wall outlet. Ensure the wall outlet provides the correct input voltage (80-140V or 140-260V) as indicated on the unit.
2. Output Voltage Selection: The unit provides both 110V and 220V output sockets. Identify the correct output socket for your appliance based on its voltage requirements.
3. Connecting Appliances: Plug your electronic appliances into the appropriate output sockets on the rear panel of the ATVR-500. Ensure the total wattage of all connected devices does not exceed 500 watts.

4. Operation

4.1 Powering On/Off

• To power on the unit, press the red ON/OFF switch on the front panel to the 'ON' position.
• The "POWER ON" LED indicator will illuminate.
• To power off, press the switch to the 'OFF' position.

4.2 Monitoring Voltage

• The front panel features an Input Voltage meter and an Output Voltage meter. These displays show the real-time voltage levels.
• The LED indicators for "IN 80-140V" and "IN 140-260V" will light up to indicate the current input voltage range.

4.3 Delay Function

• Upon powering on, the unit initiates a 3-minute (180 seconds) delay. This is indicated by the "TIME DELAY" LED.
• This delay protects sensitive appliances, especially those with motors or compressors, from damage caused by immediate power restoration after an interruption.
• After the delay, power will be supplied to the output sockets.
• A shorter 6-second delay option is also available, typically for 220V output only, as indicated by the "DELAY (6s)" LED.

4.4 Protection Features

• Over-Voltage Protection: If the input voltage exceeds 279V or the output voltage exceeds 250V, the unit will automatically cut off power to protect connected devices. The "PROTECT" LED may illuminate.
• Temperature Protection: An internal circuit protects the transformer from overheating. If the internal temperature becomes too high, the unit will temporarily shut down.
• Circuit Breaker: The rear panel includes a resettable circuit breaker. If an overload occurs, the breaker will trip.

5. Maintenance

5.1 Cleaning

• Ensure the unit is powered off and unplugged before cleaning.
• Use a soft, dry cloth to wipe the exterior surfaces.
• Do not use liquid cleaners or abrasive materials.
• Keep ventilation openings clear of dust and debris.

5.2 Circuit Breaker Reset

• If the unit stops providing power due to an overload, the circuit breaker on the rear panel may have tripped.
• Disconnect all connected appliances.
• Press the circuit breaker button to reset it.
• Reconnect appliances one by one, ensuring the total load does not exceed 500 watts.
