1. Product Overview / Обзор продукта

The Woodward 9907-018 is a cornerstone of the legendary 2301A series, specifically designed for precision speed control and load sharing of diesel engines, gas engines, or steam turbines. This low-voltage model (20–40 VDC) provides the essential logic for both single-unit isochronous operation and multi-unit load sharing in a synchronized grid. Known for its exceptional reliability and "set-it-and-forget-it" performance, the 9907-018 remains the primary choice for maintaining legacy power generation and industrial drive systems worldwide.

Ключевое преимущество: Woodward 9907-018 — это проверенный временем аналоговый регулятор серии 2301A. Он обеспечивает точное управление скоростью и распределение нагрузки в многогенераторных установках. Благодаря своей надежности и простоте настройки, эта модель (20–40 В пост. тока) является стандартом для обслуживания энергетических систем на морских судах и промышленных предприятиях.

5. FAQ / Часто задаваемые вопросы

1. Can I replace 9907-014 with 9907-018? / Можно ли заменить 9907-014 на 9907-018? No. The 9907-014 is the high-voltage version (typically 115/230 VAC), while the 9907-018 is the low-voltage DC version. Swapping them without a transformer or power supply change will damage the unit. (Нет. 9907-018 — это низковольтная версия DC, тогда как 9907-014 работает от высокого напряжения AC.)

2. What tool is needed for tuning? Since the 2301A is an analog controller, you only need a small screwdriver for tuning the potentiometers on the front panel—no computer or software is required.

3. How fast can you deliver to Atyrau? / Как быстро вы доставляете в Атырау? Via DHL Express, typical delivery to Atyrau or Almaty takes 5 to 7 working days with full tracking.
