SINOTIMER SVP912 Adjustable Voltage Überspannungsschutzrelais Benutzerhandbuch

1. Einleitung

The SINOTIMER SVP912 is an advanced adjustable voltage surge protector relay designed to safeguard electrical appliances and systems from overvoltage, Untervoltage, and overcurrent conditions. This device features a dual LED display for real-time voltage and current monitoring and offers adjustable protection parameters. It is suitable for DIN rail installation in domestic and industrial distribution boxes, providing automatic recovery of power supply once voltage returns to normal operating ranges.

2. Produktmerkmale

• Über-/Unterlautstärketage Schutz: Schaltet die Stromzufuhr automatisch ab, wenn die Lautstärketage exceeds or falls below set thresholds.
• Überstromschutz: Disconnects power if the current draw exceeds the configured limit.
• Automatische Wiederherstellung: Stellt die Stromversorgung automatisch wieder her, sobald die Stromkreisspannungtage and current return to normal operating parameters after a fault.
• Doppelte LED-Anzeige: Provides real-time display of measured voltage und aktuell.
• Adjustable Protection Values: Übervolumentage, Untervoltage, overcurrent, and fault recovery delay times are user-adjustable.
• Visuelle Indikatoren: Dedicated LED indicators (Over(V) and Under(V)) provide immediate visual feedback on protection status.
• DIN-Schieneninstallation: Designed for easy mounting within standard distribution boxes.

4. Installation und Einrichtung

The SVP912 is designed for DIN rail mounting. Ensure all power is disconnected before beginning installation to prevent electrical shock.

1. Montage: Securely attach the SVP912 to a standard 35mm DIN rail within your distribution box.
2. Verdrahtung: Connect the incoming power supply (Line 'L' and Neutral 'N') to the 'IN' terminals of the protector. Connect the load (outgoing power) to the 'OUT' terminals. Ensure correct polarity.
3. Integration von Leistungsschaltern: It is recommended to install an appropriate circuit breaker (e.g., an air circuit breaker) upstream of the voltage protector for additional safety and circuit protection.

After wiring, double-check all connections for tightness and correctness before restoring power.

5. Bedienung

Upon power-up, the SVP912 will display the current voltage and current readings. The device is pre-configured with default protection values, which can be adjusted as needed.

5.1 Anzeige und Indikatoren

• The main LED display shows the real-time voltage (V) und Strom (A).
• The 'Over(V)' LED illuminates when an overvoltagDer Zustand wird erkannt.
• The 'Under(V)' LED illuminates when an undervoltagDer Zustand wird erkannt.

5.2 Anpassen der Schutzparameter

To adjust the protection values:

1. Drücken Sie die SATZ button to enter the parameter setting mode. The display will show the first adjustable parameter (e.g., overvoltage-Schwellenwert).
2. Verwenden Sie die Nach oben (▲) Und Runter (▼) Pfeiltasten zum Erhöhen oder Verringern des Wertes.
3. Drücken SATZ again to confirm the current parameter and move to the next adjustable parameter (e.g., undervoltage threshold, overcurrent limit, recovery delay time).
4. Repeat steps 2 and 3 for all desired parameters.
5. After setting the last parameter, the device will automatically save the settings and return to normal operation mode.

Refer to the labels on the device (e.g., Uvo: AC130V-150V, Uve: AC80V-100V, Recovery time: 2-512s) for the default ranges and units of adjustable parameters.

6. Wartung

The SINOTIMER SVP912 is designed for reliable, long-term operation with minimal maintenance. Periodically inspect the device and its connections for any signs of wear, damage, or loose wiring. Ensure the area around the protector is clean and free from dust or debris to maintain proper ventilation.

7. Fehlerbehebung

Falls das Gerät nicht wie erwartet funktioniert, beachten Sie Folgendes:

• Kein Display/Keine Stromversorgung: Check the incoming power supply and ensure all wiring connections are secure. Verify the upstream circuit breaker is not tripped.
• Häufiges Auslösen: Review Ihre eingestellte Lautstärke ist zu hochtage, Untervoltage, and overcurrent thresholds. They might be set too sensitively for your application. Check for actual voltage fluctuations or excessive current draw from connected appliances.
• Device Not Recovering: Ensure the fault condition (over/undervoltage, overcurrent) has genuinely cleared and remained stable for the set recovery delay time.
• Falsche Messwerte: Wenn die angezeigte Lautstärketage or current seems inaccurate, ensure proper wiring and contact a qualified electrician for verification.

For persistent issues, consult a qualified electrician or contact SINOTIMER customer support.
