SINOTIMER SVP912 Adjustable Voltage 서지 보호기 릴레이 사용 설명서

1. 서론

The SINOTIMER SVP912 is an advanced adjustable voltage surge protector relay designed to safeguard electrical appliances and systems from overvoltag전자, 언더볼tage, 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. 제품 특징

• 오버/언더볼tage 보호: 볼륨이 일정하지 않으면 자동으로 전원이 차단됩니다.tage exceeds or falls below set thresholds.
• 과전류 보호: Disconnects power if the current draw exceeds the configured limit.
• 자동 복구: Restores power supply automatically once the circuit voltage and current return to normal operating parameters after a fault.
• 듀얼 LED 디스플레이: Provides real-time display of measured voltage와 현재.
• Adjustable Protection Values: 오버볼tag전자, 언더볼tage, overcurrent, and fault recovery delay times are user-adjustable.
• 시각적 지표: Dedicated LED indicators (Over(V) and Under(V)) provide immediate visual feedback on protection status.
• DIN 레일 설치: Designed for easy mounting within standard distribution boxes.

4. 설치 및 설정

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

1. 설치: Securely attach the SVP912 to a standard 35mm DIN rail within your distribution box.
2. 배선: 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. Circuit Breaker Integration: 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. 운영

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 디스플레이 및 표시기

• The main LED display shows the real-time voltage(V) 및 전류(A).
• The 'Over(V)' LED illuminates when an overvoltage 상태가 감지되었습니다.
• The 'Under(V)' LED illuminates when an undervoltage 상태가 감지되었습니다.

5.2 Adjusting Protection Parameters

To adjust the protection values:

1. 를 누르세요 세트 button to enter the parameter setting mode. The display will show the first adjustable parameter (e.g., overvoltage 임계값).
2. 사용하세요 위로(▲) 그리고 아래로(▼) arrow buttons to increase or decrease the value.
3. 누르다 세트 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. 유지관리

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. 문제 해결

기기가 예상대로 작동하지 않는 경우 다음 사항을 고려하십시오.

• 디스플레이 없음/전원 없음: Check the incoming power supply and ensure all wiring connections are secure. Verify the upstream circuit breaker is not tripped.
• 자주 트리핑: Review 당신의 세트 오버볼륨tag전자, 언더볼tage, 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: 고장 조건(과전압/저전압)을 확인하십시오.tage, overcurrent) has genuinely cleared and remained stable for the set recovery delay time.
• 잘못된 판독: 표시된 볼륨의 경우tage 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.
