SINOTIMER SVP912 Adjustable VoltagПосібник користувача реле захисту від перенапруги

1. Вступ

The SINOTIMER SVP912 is an advanced adjustable voltage surge protector relay designed to safeguard electrical appliances and systems from overvoltagе, підтtage, 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. Особливості продукту

• Перевищення/зниження гучностіtage Захист: Automatically disconnects power when voltage exceeds or falls below set thresholds.
• Захист від перевантаження по струму: Disconnects power if the current draw exceeds the configured limit.
• Автоматичне відновлення: Restores power supply automatically once the circuit voltage and current return to normal operating parameters after a fault.
• Подвійний світлодіодний дисплей: Provides real-time display of measured voltagе і струм.
• Adjustable Protection Values: Переволtagе, підтtage, overcurrent, and fault recovery delay times are user-adjustable.
• Візуальні індикатори: Dedicated LED indicators (Over(V) and Under(V)) provide immediate visual feedback on protection status.
• Монтаж на DIN-рейку: Designed for easy mounting within standard distribution boxes.

4. Встановлення та налаштування

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

1. Монтаж: Securely attach the SVP912 to a standard 35mm DIN rail within your distribution box.
2. Електропроводка: 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. Операція

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 Дисплей та індикатори

• The main LED display shows the real-time voltagе (В) і струм (А).
• The 'Over(V)' LED illuminates when an overvoltagВиявлено стан.
• The 'Under(V)' LED illuminates when an undervoltagВиявлено стан.

5.2 Налаштування параметрів захисту

To adjust the protection values:

1. Натисніть НАБІР button to enter the parameter setting mode. The display will show the first adjustable parameter (e.g., overvoltagпоріг).
2. Використовуйте Вгору (▲) і Вниз (▼) arrow buttons to increase or decrease the value.
3. Прес НАБІР 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. Технічне обслуговування

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. Вирішення проблем

Якщо пристрій не працює належним чином, зверніть увагу на наступне:

• Немає дисплея/немає живлення: Check the incoming power supply and ensure all wiring connections are secure. Verify the upstream circuit breaker is not tripped.
• Часте відключення: Review перевищення гучності вашого наборуtagе, підтtage, 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: Ensure the fault condition (over/undervoltage, overcurrent) has genuinely cleared and remained stable for the set recovery delay time.
• Неправильні показання: Якщо відображена обtage 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.
