1. Introduction
The MCR SINOTIMER SVP-915A is an advanced adjustable voltage protector designed to safeguard electrical appliances and systems from voltage fluctuations and overcurrent conditions. It features an LCD display for real-time monitoring of voltage, current, and power consumption (KWH). This device integrates over-voltage, sous-voltage, and overload protection functions, automatically disconnecting the power supply when abnormal conditions are detected and reconnecting when safe levels are restored. It is suitable for DIN rail mounting in various electrical distribution systems.

4. Configuration et installation
Before proceeding with installation, ensure all safety precautions are observed, especially disconnecting the main power supply.
4.1. Montage sur rail DIN
- Repérez un rail DIN de 35 mm approprié dans votre tableau électrique.
- Align the device's mounting clip with the DIN rail.
- Press the device firmly onto the rail until it clicks into place. Ensure it is securely fastened.
Figure 4.1 : Bas view Illustrant le mécanisme de montage sur rail DIN.
4.2. Connexions de câblage
Refer to the wiring diagram below for correct connection. The device is designed for single-phase systems.
Figure 4.2: Wiring Diagram for SINOTIMER SVP-915A.
- Entrée (ENTRÉE) : Connect the incoming Live (L) and Neutral (N) wires from your power source (e.g., main breaker or power switch) to the 'IN' terminals of the SVP-915A.
- Sortie (SORTIE) : Connect the outgoing Live (L) and Neutral (N) wires to your load (e.g., distribution panel or appliances) from the 'OUT' terminals of the SVP-915A.
- Assurez-vous que toutes les connexions sont bien serrées et sécurisées afin d'éviter les faux contacts et la surchauffe.
4.3. Mise sous tension initiale
After verifying all connections, restore power to the circuit. The device's LCD display should illuminate, showing the current voltage. The device will perform a self-test and then enter normal operating mode.
5. Mode d'emploi
5.1. Modes d'affichage
The LCD continuously displays the current voltage (U). Pressing the "Up" or "Down" buttons briefly will cycle through other display parameters:
- VoltagUE): Vol de ligne actueltage en Volt (V).
- Courant (A): Current load in Ampères (A).
- Puissance (W) : Real-time power consumption in Watts (W).
- Énergie (kWh) : Accumulated power consumption in Kilowatt-hours (KWH).
5.2. Réglage des paramètres de protection
To enter the settings mode and adjust protection thresholds:
- Press and hold the "SET" button for approximately 3-5 seconds until the display starts flashing, indicating entry into settings mode.
- Use the "SET" button to cycle through the adjustable parameters:
- Survoltage protection threshold (UVP): Réglez le volume maximal autorisétage.
- Sous-voltage protection threshold (OVP): Définir le volume minimal autorisétage.
- Over-current protection threshold (OCP): Réglez le courant maximal admissible.
- Reconnection delay time: Time before the device reconnects after a fault.
- While a parameter is flashing, use the "Up" and "Down" arrow buttons to adjust its value.
- After setting all desired parameters, press and hold the "SET" button again for 3-5 seconds, or wait for 10 seconds without any button press, to save the settings and exit the settings mode.
5.3. Resetting KWH
To reset the accumulated KWH reading, enter the settings mode, navigate to the KWH display, and then press and hold both "Up" and "Down" buttons simultaneously until the KWH value resets to zero.
6. Entretien
The SINOTIMER SVP-915A is designed for minimal maintenance. However, periodic checks can ensure optimal performance and longevity.
- Nettoyage: Gently wipe the device with a dry, soft cloth to remove dust. Do not use liquid cleaners or abrasive materials.
- Vérification de la connexion : Periodically inspect wiring connections to ensure they remain tight and free from corrosion. (Ensure power is disconnected before inspection).
- Conditions environnementales : S’assurer que l’environnement de travail reste dans les limites spécifiées (température, humidité).
7. Dépannage
If you encounter issues with your SVP-915A, refer to the following common problems and solutions:
| Problème | Cause possible | Solution |
|---|---|---|
| Aucun affichage / L'appareil ne s'allume pas | No input power; Incorrect wiring; Device fault. | Check main power supply. Verify input wiring (L and N). If power is present and wiring is correct, the device may be faulty. |
| Les appareils se déclenchent fréquemment | Survoltage, sous-voltage, or over-current condition; Protection thresholds set too low/high. | Check actual line voltage and load current. Adjust protection thresholds if necessary (refer to Section 5.2). Reduce load if over-current is detected. |
| Affichage de lectures incorrectes | Wiring error; Device calibration issue. | Verify wiring connections. If readings are consistently inaccurate, the device may require service. |
| Device does not reconnect after fault | Fault condition still present; Reconnection delay too long; Device fault. | Ensure the fault condition (over/under voltage, over current) has cleared. Check reconnection delay setting. If the fault has cleared and delay passed, device may be faulty. |
Si le problème persiste après avoir essayé ces solutions, veuillez contacter le service client.
