1. Product Overview / Обзор продукта

The Woodward 9907-167 is a specialized version of the legendary 2301A Load Sharing and Speed Control series. Specifically engineered for high-voltage environments (88–132 VAC or 90–150 VDC), this module is distinguished by its Reverse Acting control logic. In a reverse-acting configuration, the controller decreases its output signal as the engine speed increases—a critical requirement for specific actuator types designed for fail-safe or specialized mechanical architectures. Like all 2301A units, the 9907-167 offers unmatched analog reliability for synchronizing and load balancing in complex power generation and marine propulsion systems.

Ключевое преимущество: Woodward 9907-167 — это высоковольтный регулятор серии 2301A с обратным действием (Reverse Acting). Он предназначен для систем, где управляющий сигнал должен уменьшаться при увеличении скорости двигателя. Работает в диапазоне 88–132 В перем. тока или 90–150 В пост. тока, обеспечивая стабильное распределение нагрузки и контроль скорости на крупных промышленных и морских объектах.

5. FAQ / Часто задаваемые вопросы

1. What is the main difference between 9907-164 and 9907-167? / В чем разница между 9907-164 и 9907-167? Both are High Voltage. However, 9907-164 is Forward Acting, and 9907-167 is Reverse Acting. Using the wrong one will cause the engine to fail to control speed or result in a dangerous overspeed. (Оба высоковольтные, но 9907-164 — прямого действия, а 9907-167 — обратного. Ошибка в выборе может привести к потере контроля над скоростью двигателя.)

2. Can it be used for single-unit operation? Yes, it can be used for both single-unit speed control (Isochronous/Droop) and multi-unit load sharing.

3. How fast is delivery to Poland or Kazakhstan? / Как быстро осуществляется доставка в Польшу или Казахстан? Via DHL Express, typical delivery to Warsaw, Almaty, or Atyrau takes 5 to 7 working days.
