User Manual: Three-Phase Adjustable Over/Under Voltage Olugbeja

1. Ifihan

The SINOTIMER STVP series automatic over-voltage ati labẹ-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, labẹ-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, labẹ-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.

The protector is designed for 35mm DIN rail installation. Snap the device onto the DIN rail securely.

5.3 Wiring aworan atọka

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.

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).

Ni irú ti ẹya lori-voltage, labẹ-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.

8.1 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 overvoltage awọn iṣẹlẹ.
• "<U" for undervoltage awọn iṣẹlẹ.

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.
