1. Pengenalan
The SINOTIMER STVP series automatic over-voltage dan di bawah voltage protector is designed for three-phase 3*127V/220VAC power systems with a rated working current of 80A. This device provides essential protection for electrical equipment by instantaneously cutting off the power supply when over-voltage, bawah-voltage, or over-current conditions are detected. Once the circuit voltage returns to normal, the protector automatically restores power, ensuring continuous operation and safeguarding your appliances from damage.
This protector integrates multiple protection functions including over-voltage, bawah-voltage, over-current, three-phase current (voltage) imbalance, phase sequence (reverse phase), zero-break, and phase-break protection. It also features voltmeter and ammeter functions, and the ability to restore factory settings. The device offers comprehensive features, stable performance, and ease of operation.

4. Maklumat Keselamatan
- Pemasangan dan penyelenggaraan hendaklah hanya dilakukan oleh juruelektrik yang bertauliah.
- Pastikan bekalan kuasa diputuskan sambungannya sebelum sebarang kerja pemasangan atau pendawaian.
- The device does not provide overload or short-circuit protection. It must be used in conjunction with appropriate external circuit breakers (e.g., C45, C65 mini circuit breakers) for comprehensive protection.
- Sahkan semua sambungan pendawaian adalah selamat dan betul sebelum menggunakan kuasa.
- Do not operate the device in wet or hazardous environments.
5. Pemasangan
5.1 Dimensi Fizikal
5.2 Pemasangan
The protector is designed for 35mm DIN rail installation. Snap the device onto the DIN rail securely.
5.3 Gambarajah Pendawaian
Connect the input and output terminals as shown in the diagram below. Ensure correct phase (L1, L2, L3) and neutral (N) connections. The input terminals are located at the top, and output terminals at the bottom.
6. Persediaan dan Tatarajah
Untuk memasuki mod tetapan, tekan dan tahan butang SET button for 3 seconds. Then, continuously press SET to cycle through the parameters. Use the ▲ dan ▼ buttons to adjust the values. When "ENd" appears, press SET again to save the data and exit the setting mode.
If no operation is performed within 10 seconds after pressing SET, the device will automatically exit the setting mode, and any unsaved changes will be lost.

6.2 Tetapan Semula Kilang
To reset the device to factory settings, press and hold the ▲ dan ▼ butang serentak selama 3 saat.
7. Operasi
Once installed and configured, the device will continuously monitor the three-phase power supply. The LCD screen will automatically rotate to display the real-time voltage and current for each phase (L1, L2, L3).
Sekiranya berlaku lebihan voltage, bawah-voltage, or over-current event, the protector will automatically trip and cut off the power supply to protect connected equipment. After the fault condition clears and the recovery delay time has passed, the device will automatically restore power.
8. Penyelesaian masalah
8.1 Fault Inquiry
If a fault occurs, the device will display an error code (E0). You can press the ▲ button to query the last 5 fault records (E1-E5). The display will indicate:
- ">U" for overvoltagacara e.
- "<U" for undervoltagacara e.
8.2 Phase Sequence Error
If the LCD displays "ABC" character, it indicates a phase sequence error. To correct this, arbitrarily reverse any two of the three phase lines (L1, L2, L3) at the input.
9. Penyelenggaraan
- Pastikan peranti bersih dan bebas daripada habuk dan lembapan.
- Regularly check wiring connections for tightness and signs of wear or damage.
- Do not attempt to repair the device yourself. Refer to qualified personnel for service.
