SINOTIMER SVP-915A Adjustable Voltage Protector and Energy Meter

1. Product Overview

The SINOTIMER SVP-915A is an automatic over-voltage and under-voltage protector designed for single-phase AC 230V, 50/60Hz systems, with a rated working current of up to 63A or 80A (adjustable). It is primarily intended for residential household box entry or for protecting single-phase electrical equipment on distribution lines against over-voltage, under-voltage, or over-current conditions.

When the circuit experiences over-voltage, under-voltage, or over-current issues, the device instantaneously cuts off the power supply to protect electrical equipment from damage. It automatically restores power once the circuit voltage returns to normal levels.

The device features an LCD display that shows voltage, current, and energy (kWh) measurements. A green indicator signifies normal power supply, while a red indicator signals over-voltage or under-voltage conditions.

6. Maintenance

6.1 Restoring Factory Settings

To restore the device to its default factory settings:

1. Press and hold both the ▲ and ▼ buttons simultaneously for 3 seconds.
2. The LCD screen will flash once, indicating that the default parameter values have been restored.

7. Troubleshooting

7.1 Fault Inquiry

The device can display the last 5 fault events. To inquire about faults:

1. Enter the setting mode by pressing and holding SET for 3 seconds.
2. Cycle through the settings using the SET button until "E" is displayed on the LCD.
3. Press the ▲ button to view the last 5 recorded faults.

Fault codes and their meanings:

• Uov: Over-voltage event
• Uvu: Under-voltage event
• Io: Over-current event
• IR: Bad load event (if applicable to model variant)

8. User Tips

• Initial Connection Delay: Remember to wait approximately 1 minute after initial power-on for the device to stabilize and the red indicator light to turn off before expecting normal operation.
• Customizing Protection: Take advantage of the adjustable parameters for over-voltage, under-voltage, and over-current protection to tailor the device's response to your specific electrical system and connected equipment.
• Monitoring: Regularly check the LCD display for real-time voltage, current, and kWh readings to monitor your electrical consumption and system health.
