SINOTIMER SVP-912 Adjustable Automatic Reconnect Protection Device

1. Introduction

The SINOTIMER SVP-912 is an advanced adjustable automatic reconnect protection device designed to safeguard your household appliances and electrical systems from over-voltage and under-voltage conditions. This device features a dual LED display for real-time voltage and current monitoring, along with adjustable protection parameters to suit various electrical environments. Its automatic recovery function ensures continuous power supply after a fault is cleared, providing reliable and convenient protection.

2. Safety Information

• Installation and maintenance should only be performed by qualified electricians.
• Ensure the main power supply is disconnected before any installation or wiring.
• Do not operate the device if it appears damaged or faulty.
• This device is designed for indoor use only and should be protected from moisture and extreme temperatures.
• Verify all connections are secure and correctly wired to prevent electrical hazards.

3. Product Overview

The SVP-912 is a compact, DIN rail-mountable device featuring a clear dual LED display. One display shows the current voltage, and the other shows the current. It includes three buttons (SET, Up, Down) for easy parameter adjustment. Indicator lights provide visual feedback on the device's status, including over-voltage and under-voltage conditions.

5. Setup and Installation

5.1 Mounting

The SVP-912 is designed for 35mm DIN rail mounting. Simply clip the device onto the DIN rail in your electrical distribution box.

5.2 Wiring Diagram

Refer to the following diagram for correct wiring. Ensure all connections are tight and follow local electrical codes.

• IN (Input): Connect the incoming Line (L) and Neutral (N) wires from your main power source or upstream circuit breaker.
• OUT (Output): Connect the outgoing Line (L) and Neutral (N) wires to the load (e.g., household appliances, distribution circuit).
• Ensure proper grounding if required by your electrical system.

6. Operating Instructions

6.1 Initial Power-On

Upon initial power-on, the device will undergo a self-check. The under-voltage indicator LED will not light during the power-on delay time (default 2s) until the protector is closed after the delay time. The LED display will show the current voltage.

6.2 Parameter Adjustment

To adjust protection parameters:

1. Press the SET button once to enter the setting mode. The first adjustable parameter will flash.
2. Use the ▲ (Up) and ▼ (Down) buttons to change the value.
3. Press SET again to confirm the value and move to the next parameter.
4. Repeat steps 2 and 3 for all desired parameters.
5. If no button is pressed for a few seconds, the device will automatically exit setting mode and save the changes.

Adjustable parameters and their default values:

• Over-voltage protection value: 221V ~ 300V (OFF), default: 280V
• Over-voltage recovery value: 220V ~ 299V, default: 250V
• Over-voltage protection action time: 0.1s ~ 10s, default: 0.1s
• Under-voltage protection value: 150V ~ 219V (OFF), default: 160V
• Under-voltage recovery value: 151V ~ 220V, default: 180V
• Under-voltage protection action time: 0.1s ~ 10s, default: 0.1s
• Recovery delay time: 2s ~ 512s, default: 60s (Time before device reconnects after a fault)
• Power-on delay time: 2s ~ 255s, default: 2s (Delay before device powers on after initial connection or power restoration)

6.3 Indicator Lights

• Voltage indicator: Flashes quickly during over-voltage, slowly during under-voltage. Stays on constantly during normal operation (within warranty period).
• Over-voltage indicator: Red LED, indicates over-voltage condition.
• Under-voltage indicator: Red LED, indicates under-voltage condition.
• Power indicator: Green LED, indicates device is powered on.

6.4 Restore Factory Settings

To restore the device to its default factory settings, press and hold the ▲ (Up) and ▼ (Down) buttons simultaneously for 3 seconds. The under-voltage indicator LED will turn off for 1 second, confirming that the factory settings have been restored.

7. Troubleshooting

• Device not powering on: Check the input power supply and ensure connections are secure.
• Device not reconnecting after fault: Verify the "Recovery delay time" setting. If set to OFF, manual reset might be required (though this model is automatic reconnect). Ensure the fault condition (over/under voltage) has cleared.
• Incorrect voltage/current display: Ensure proper wiring. If the issue persists, contact support.
• Frequent tripping: Review your set over-voltage and under-voltage protection values. They might be too sensitive for your electrical environment. Adjust them within safe limits.

8. User Tips

• Test Settings: After adjusting any parameters, it is recommended to simulate a fault condition (if safely possible) or monitor the device closely to ensure it operates as expected.
• Optimal Placement: Install the protector in a location that is easily accessible for monitoring and adjustments, but also protected from physical damage and environmental factors.
• Regular Checks: Periodically check the display for normal operation and ensure no error indicators are active.

9. Maintenance

• Keep the device clean and free from dust. Use a dry, soft cloth for cleaning.
• Do not use abrasive cleaners or solvents.
• Periodically inspect wiring connections for tightness and signs of wear or corrosion.
• No user-serviceable parts inside. Do not attempt to open or repair the device.
