1. Product Overview / Обзор продукта

The Woodward 9907-164 is a high-reliability 2301A Load Sharing and Speed Control unit designed for high-voltage applications. Unlike its low-voltage counterparts, the 9907-164 operates on 88–132 VAC or 90–150 VDC, making it the standard choice for industrial facilities and marine vessels where high-voltage control power is utilized. This analog controller is "Forward Acting" and provides precise engine speed management and load balancing for multi-generator synchronized systems. Its robust, fan-less design ensures decades of operation in vibration-heavy and thermally demanding environments.

Ключевое преимущество: Woodward 9907-164 — это высоковольтная версия легендарного регулятора 2301A. Он работает в диапазоне 88–132 В перем. тока или 90–150 В пост. тока. Это идеальное решение для модернизации и обслуживания систем управления генераторами на крупных промышленных объектах и судах, где требуется работа с высоким напряжением без дополнительных преобразователей.

5. FAQ / Часто задаваемые вопросы

1. Can I use 9907-164 to replace a 24VDC 9907-018? / Можно ли заменить 9907-018 на 9907-164? No. The 9907-164 requires high voltage. Connecting it to a 24VDC system will result in the unit failing to power up. Conversely, connecting a 018 to high voltage will destroy it instantly. (Нет. Эти модули имеют разное напряжение питания. 9907-164 требует высокого напряжения.)

2. What is "Forward Acting"? In a forward-acting system, the controller increases its output signal to the actuator to increase fuel. This must match your actuator's physical requirements.

3. How long is delivery to Kazakhstan? / Сколько времени занимает доставка в Казахстан? Via DHL or FedEx Express, typical delivery to Atyrau or Almaty takes 5 to 7 working days with full tracking.
