3. Особенности продукта
The MARSTEK Triple Power 63A ATS offers a range of features designed for reliable power management:
- Triple-Source Automatic Switching: Seamlessly transfers loads between Primary, Backup 1, and Backup 2 power sources during outagда, томtage sags/surges, or irregularities. Automatically reverts to the preferred source once stable.
- Built-in Electrical Protection: Safeguards connected equipment with advanced Overvoltage (140V max), Undervoltage (90V min), and Overcurrent (63A max) protection, preventing damage from unstable power.
- Flexible Priority Phase Setting: Designate ANY input (L1/L2/L3) as Primary—optimize for cost, reliability, or grid conditions without fixed "Main" limitations.
- Real-Time LED Voltagд Мониторинг: Intuitive display shows live voltage levels (e.g., 120V, 108V) for all 3 sources, with instant status indicators for active source, transfer, and faults.
- Quick DIN Rail Installation & Compact Design: Space-saving unit installs in minutes via standard DIN rail mounting, rated for 63A at AC 110V with a 106 mechanical lifespan.

6. Установка
6.1 Монтаж на DIN-рейку
The MARSTEK ATS is designed for quick and easy installation on a standard DIN rail.
- Ensure all power sources are disconnected and verified as de-energized.
- Align the back panel display of the ATS with the DIN rail.
- Press the latch located on the bottom of the ATS.
- Insert the ATS onto the DIN rail.
- Release the latch to secure the ATS firmly in place. You should hear a "click" sound.
Image: Step-by-step visual guide for installing the ATS onto a DIN rail, demonstrating the alignment, latch pressing, insertion, and latch release process.
6.2 Схема электропроводки
Refer to the following diagram for correct wiring connections. Ensure all connections are tight and properly insulated.
Image: Detailed wiring diagram illustrating the input connections for Neutral (N), Line 1 (L1), Line 2 (L2), Line 3 (L3), and output connections for Neutral (N) and Line (L).
- Входные клеммы: Connect your three power sources (e.g., Utility, Generator, Inverter) to L1, L2, and L3 respectively. Connect the neutral lines to the N terminals.
- Выходные клеммы: Connect your load to the N (Neutral) and L (Line) output terminals.
- Важный: Ensure correct phase and neutral connections. Incorrect wiring can damage the device or connected equipment.
7. Операция
7.1 Power-On and Initial State
Once wired and power is applied, the ATS will perform a self-check. The LED display will show the voltage levels of the connected sources. The device will automatically select the primary source (as configured) if it is stable and within acceptable parameters.
Image: Close-up of the multi-function digital adjustment panel, featuring a high-definition LED display for real-time voltage and current monitoring, alongside menu options for customizing parameters.
7.2 Automatic Switching Logic
The ATS continuously monitors the voltage and stability of all three connected power sources. The switching logic is as follows:
- If the designated primary source (L1, L2, or L3) is stable and within acceptable voltage/current limits, the load will be connected to it.
- If the primary source experiences an outagе, томtage sag/surge, or overcurrent condition, the ATS will automatically transfer the load to the next available stable backup source (Backup 1, then Backup 2).
- Once the primary source is restored and stabilized, the ATS will automatically revert the load back to the primary source after a configurable delay.
Image: Flowchart depicting the automatic switching mechanism, showing how the ATS transitions between the normal power source and backup sources in response to power outages или voltage abnormalities, and reverts once stability is restored.
7.3 Настройка параметров
The ATS features a digital adjustment panel for customizing various parameters. Use the 'M' (Menu), 'Up' (Digit+), and 'Down' (Digit-) buttons to navigate and adjust settings.
- Power-on delay time (PE): Time delay before the ATS powers on after initial power application.
- Transfer time/Protection recovery delay time (rE): Delay before switching to a backup source or reverting to primary.
- ОверволtagЗначение защиты e (oU): Sets the upper voltagе предел.
- Андерволtage protection value (UU): Sets the lower voltagе предел.
- Priority phase (PS): Designate L1, L2, or L3 as the primary power source.
- Значение защиты от перегрузки по току (°C): Sets the maximum current limit.
- Overcurrent protection action time (CtT): Delay before overcurrent protection trips.
- Частота непрерывной защиты от перегрузки по току (CC): How often overcurrent protection can trip.
Refer to the on-screen menu for specific navigation and adjustment procedures. Always ensure settings are appropriate for your electrical system and connected loads.
8. Техническое обслуживание
The MARSTEK ATS is designed for minimal maintenance. However, regular checks can ensure optimal performance and longevity:
- Визуальный осмотр: Периодически осматривайте устройство на наличие признаков механических повреждений, ослабленных соединений или изменения цвета.
- Проверка подключения: Ensure all wiring terminals remain tight. Loose connections can lead to overheating and device failure.
- Чистота: Следите за тем, чтобы устройство не загрязнялось пылью и мусором. Для чистки используйте сухую мягкую ткань. Не используйте жидкие чистящие средства.
- Тест функциональности: If possible and safe to do so, periodically test the automatic transfer function by simulating a power outage on the primary source.
ВНИМАНИЕ: Перед выполнением любых работ по техническому обслуживанию или чистке всегда отключайте питание.
9. Поиск Неисправностей
| Проблема | Возможная причина | Решение |
|---|---|---|
| Устройство не включается. | Отсутствие входного питания; неправильная проводка; внутренняя неисправность. | Verify input power to L1/L2/L3 and N terminals. Check wiring against diagram. If power is present and wiring is correct, contact support. |
| Автоматический перевод не предусмотрен. | Backup source not stable; primary source still active; incorrect settings (e.g., transfer delay). | Проверить объемtage of backup sources. Ensure primary source is truly unavailable. Review transfer delay settings (rE). |
| Frequent tripping (Overvoltagе / Undervoltage/Overcurrent). | Unstable power supply; load exceeds rating; protection settings too sensitive. | Monitor power quality. Reduce load if exceeding 63A. Adjust protection thresholds (oU, UU, oC) if appropriate for your system, but do not exceed safe limits. |
| GFI/GFCI trips when using a generator. | Generator has a neutral-ground bond, creating multiple bonding points when connected to a house system. | This ATS is designed for systems where neutral and ground are bonded at a single point (e.g., main service panel). If using a neutral-bonded portable generator, consult a qualified electrician for proper isolation or alternative wiring solutions to avoid ground fault issues. |
| LED display shows "Fault". | Indicates an error condition (e.g., overvoltagе, андерволtag(например, перегрузка по току). | Check the specific fault indicator (L1, L2, L3, Fault LED). Address the underlying power issue or load condition. Review настройки защиты. |
