SINOTIMER SVP912 Adjustable VoltagРуководство пользователя реле защиты от перенапряжения

1. Введение

The SINOTIMER SVP912 is an advanced adjustable voltage surge protector relay designed to safeguard electrical appliances and systems from overvoltagе, андерволtage, 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. Особенности продукта

• Больше/меньше громкостиtagЭлектронная защита: Автоматически отключает питание при изменении громкостиtage превышает или опускается ниже установленных пороговых значений.
• Защита от сверхтока: Disconnects power if the current draw exceeds the configured limit.
• Автоматическое восстановление: Автоматически восстанавливает подачу питания после отключения питания цепи.tage and current return to normal operating parameters after a fault.
• Двойной светодиодный дисплей: Provides real-time display of measured voltagе и ток.
• Регулируемые значения защиты: Оверволtagе, андерволtage, overcurrent, and fault recovery delay times are user-adjustable.
• Визуальные индикаторы: Dedicated LED indicators (Over(V) and Under(V)) provide immediate visual feedback on protection status.
• Установка на DIN-рейку: Designed for easy mounting within standard distribution boxes.

4. Установка и настройка

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. Проводка: 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. Интеграция автоматических выключателей: 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.

После подключения проводов, перед возобновлением подачи питания, дважды проверьте надежность и правильность всех соединений.

5. Операция

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 и индикаторы

• The main LED display shows the real-time voltagе (В) и ток (А).
• The 'Over(V)' LED illuminates when an overvoltagОбнаружено состояние.
• The 'Under(V)' LED illuminates when an undervoltagОбнаружено состояние.

5.2 Настройка параметров защиты

To adjust the protection values:

1. Нажмите НАБОР button to enter the parameter setting mode. The display will show the first adjustable parameter (e.g., overvoltagе порог).
2. Используйте Вверх (▲) и Вниз (▼) arrow buttons to increase or decrease the value.
3. Нажимать НАБОР again to confirm the current parameter and move to the next adjustable parameter (e.g., undervoltage threshold, overcurrent limit, recovery delay time).
4. Повторите шаги 2 и 3 для всех желаемых параметров.
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. Техническое обслуживание

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. Поиск Неисправностей

Если устройство работает некорректно, рассмотрите следующие варианты:

• Нет дисплея/нет питания: Check the incoming power supply and ensure all wiring connections are secure. Verify the upstream circuit breaker is not tripped.
• Частые отключения: Review ваш набор перегрузокtagе, андерволtage, 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.
• Неправильные показания: Если отображаемый объемtage 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.
