The Woodward BU1AC110 appears to be an AC Voltage Relay. Based on the search results, here's a detailed product description:
Product Name: Woodward BU1AC110 (often seen as BU1-AC110 or BU1-AC)
Manufacturer: Woodward SEG (Woodward, Inc. is a leading company in control solutions for power generation and industrial markets. SEG was a company acquired by Woodward.)
Product Type: AC Voltage Relay
Function/Application:The BU1AC110 is designed to monitor AC voltage. Voltage relays like this are crucial components in various industrial and power generation applications, typically used for:
Voltage Protection: Protecting equipment from over-voltage or under-voltage conditions by tripping a circuit when voltage falls outside acceptable limits.
Grid Synchronization: In power generation, they can be used to monitor the grid voltage and facilitate the synchronization of generators.
Load Shedding/Management: Helping to manage electrical loads by monitoring voltage levels and initiating actions (like shedding non-critical loads) when necessary to maintain system stability.
Industrial Automation: Integrated into control systems to provide voltage-based interlocking or control signals for machinery and processes.
Key Features (Based on typical voltage relays and limited specific information):
Voltage Sensing: Designed to accurately detect and measure AC voltage.
Trip/Setpoint Adjustment: Likely features adjustable setpoints for over-voltage and/or under-voltage thresholds, allowing customization based on the application's requirements.
Time Delay: Often includes adjustable time delays to prevent nuisance tripping due to momentary voltage fluctuations.
Relay Output: Equipped with a relay output (e.g., normally open/normally closed contacts) to activate alarms, trip circuit breakers, or send signals to other control systems when a voltage anomaly is detected.
Robust Design: As an industrial component, it would be built for durability and reliability in demanding environments.
Mounting: Likely designed for panel mounting or DIN rail mounting, typical for industrial control panels.
Technical Specifications (General, as specific detailed specs for this exact model were not readily available in the brief search results):
Nominal Voltage: The "110" in BU1AC110 strongly suggests a nominal operating voltage of 110 VAC. Other variations (like 230VAC also mentioned in a search result for a similar model) might exist for the BU1-AC series.
Output Contact Rating: The maximum current and voltage the relay contacts can switch (e.g., 5A @ 250VAC).
Operating Temperature Range: The environmental conditions it can withstand.
Protection Class: Its resistance to dust and water (e.g., IP rating).
Typical Industries/Environments:
Power Plants (conventional, renewable)
Industrial Manufacturing Facilities
Utilities and Grid Infrastructure
Marine and Offshore Applications
Heavy Machinery
Note: For precise and complete specifications, it is always recommended to consult the official product datasheet or manual from Woodward, Inc.
