- Doppio display LED: Real-time display of measured voltage and current for continuous monitoring.
- Adjustable Protection Parameters: Sovravoltage, sottovoltage, overcurrent thresholds, and fault recovery delay times are fully adjustable to suit specific requirements.
- Protezione completa: Fornisce protezione contro il sovra-volttage, sotto-volumetage, and over-current issues for residential household box entry or distribution lines.
- Economical Load Capacity: Available in various resistive load capacities, including 40A, suitable for typical residential applications.
2. Precauzioni di sicurezza
ATTENZIONE: Pericolo di scossa elettrica. L'installazione e la manutenzione devono essere eseguite solo da personale qualificato. Scollegare l'alimentazione prima dell'installazione o della manutenzione.
- Ensure the main power supply is disconnected before attempting any installation or wiring.
- Verify that the protector's current rating matches or exceeds the expected load.
- The neutral line (N) of the protector is directly connected and does not have a disconnection function. Ensure proper wiring according to local electrical codes.
- Non utilizzare il dispositivo se appare danneggiato.
3. Configurazione e installazione
3.1 Dimensioni del prodotto
Before installation, verify the physical dimensions of the protector to ensure it fits within your electrical panel or enclosure.
Immagine 3.1: Davanti e di lato view of the SINOTIMER Adjustable Voltage Protector with key dimensions indicated. The device measures 85mm in height, 35mm in width, and 65mm in depth (including the DIN rail clip), designed for compact installation.
3.2 Montaggio
The SINOTIMER SVP-916 is designed for surface mounting, typically on a DIN rail within an electrical distribution box. Ensure a secure and stable mounting location.
3.3 Collegamenti di cablaggio
Follow the wiring diagram carefully. Incorrect wiring can lead to device malfunction or electrical hazards. The protector has clearly marked "IN" (Input) and "OUT" (Output) terminals for Line (L) and Neutral (N).
Immagine 3.2: Wiring diagram illustrating the connection of the SINOTIMER Adjustable Voltage Protector (SVP-916) within an electrical circuit. It shows the protector connected between a power switch and an air circuit breaker, with clear indications for Line (L) and Neutral (N) inputs and outputs.
- Connect the incoming Line (L) and Neutral (N) wires from your power source to the "IN" terminals of the protector.
- Connect the outgoing Line (L) and Neutral (N) wires from the "OUT" terminals of the protector to your load (e.g., distribution panel, circuit breaker).
- Assicurarsi che tutti i collegamenti siano ben saldi e sicuri per evitare contatti allentati e surriscaldamento.
3.4 Accensione iniziale
After wiring, restore power to the circuit. The protector's LED displays should illuminate, showing the current voltage and current readings. The device will perform a self-check and then enter normal operating mode.
4. Funzionamento
4.1 Display a LED
The SVP-916 features two LED displays for real-time monitoring:
Immagine 4.1: The SINOTIMER Adjustable Voltage Protector displaying voltage (red LED) and current (green LED) readings. The control buttons (SET, Up, Down) are visible below the displays.
- Upper (Red) Display: Mostra il volume misuratotage(V).
- Lower (Green) Display: Shows the measured current (A).
- Luci di segnalazione: Small LEDs indicate Overvoltage (OV: fast blink), Undervoltage (UV: slow blink), and Overcurrent (OC: fast blink).
4.2 impostazioni regolabili
The protector allows adjustment of various parameters to customize protection levels. Use the IMPOSTATO, ▲ (Up), and ▼ (Down) buttons to navigate and modify settings.
- Sovravoltage Protection Value (OV): Sets the maximum allowable voltage.
- Sottovoltage Protection Value (UV): Sets the minimum allowable voltage.
- Overcurrent Protection Value (OC): Sets the maximum allowable current.
- Fault Recovery Delay Time (t-on): Sets the delay before the device automatically reconnects after a fault clears.
- Sottovoltage Breaking Time (t-off): Sets the delay before the device trips on undervoltage. Note: If this time is greater than 0.3 seconds, the protector may not open immediately after a power failure.
4.3 Setting Adjustment Procedure
- Premere e tenere premuto il tasto IMPOSTATO button for a few seconds to enter the setting mode.
- Utilizzare il IMPOSTATO button to cycle through the different parameters (OV, UV, OC, t-on, t-off).
- Utilizzare il ▲ (Su) e ▼ (Down) buttons to adjust the value of the selected parameter.
- Once all desired settings are configured, wait for a few seconds without pressing any buttons. The device will automatically save the settings and exit the setting mode.
5. Manutenzione
The SINOTIMER Voltage Protector is designed for long-term, reliable operation with minimal maintenance. However, periodic checks can help ensure optimal performance.
- Pulizia: Keep the device clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Verifica della connessione: Ispezionare periodicamente i collegamenti dei cavi per assicurarsi che siano sempre ben saldi e privi di corrosione.
- Condizioni ambientali: Per evitare danni, assicurarsi che l'ambiente operativo rimanga entro gli intervalli di temperatura e umidità specificati.
- Prova di funzionalità: If possible and safe to do so, periodically test the protection functions by simulating an over-voltage o sotto-volumetage condition (e.g., using a variable power supply, if available and safe).
6. Risoluzione Dei Problemi
This section addresses common issues you might encounter with the SINOTIMER Voltage Protettore.
| Problema | Possibile causa | Soluzione |
|---|---|---|
| No display/No power output. | Nessuna alimentazione in ingresso; cablaggio errato; guasto interno. | Verify input power supply. Check wiring connections (L and N). If power is present and wiring is correct, the device may be faulty. |
| Il dispositivo scatta frequentemente. | Voltage/current fluctuations exceeding set limits; incorrect settings; overloaded circuit. | Check actual voltage/current readings. Adjust OV/UV/OC settings if necessary, ensuring they are appropriate for your system. Reduce load if circuit is overloaded. |
| Does not automatically reconnect. | Fault condition still present; t-on delay set too long; internal fault. | Ensure the fault condition (over/under voltage/current) has cleared. Check the t-on (recovery delay) setting. If the fault has cleared and delay is appropriate, device may require manual reset (power cycle) or be faulty. |
| Vol. imprecisotagletture e/correnti. | Loose connections; device malfunction. | Check all wiring connections for tightness. Compare readings with a calibrated multimeter. If readings are consistently off, the device may be faulty. |
| Sottovoltage trip delay issue. | t-off setting is too high (greater than 0.3 seconds). | Adjust the t-off setting to a value less than or equal to 0.3 seconds if immediate disconnection upon undervoltage is desired. |
