GE DS3800NECA/RR LCI Exc Volt Cont
The GE DS3800NECA/RR is an industrial circuit board assembly designed to function as an LCI (Load Commutated Inverter) Excitation Voltage Controller. It’s a key component in large motor control systems, specifically those that use Load Commutated Inverters to manage high-power AC motors. Its main job is to precisely control the excitation voltage, which in turn regulates the motor’s speed and torque.
Key Specifications
- Type: LCI Excitation Voltage Controller
- Part Number: DS3800NECA/RR
- Compatibility: GE LCI-based drive systems
- Function: Regulates and controls excitation voltage for AC motors or synchronous machines.
- Application: Industrial automation, motor control, power generation.
Detailed Overview
In systems that use Load Commutated Inverters, the excitation voltage is critical for controlling the machine’s performance. The DS3800NECA/RR acts as the dedicated brain for this task. It takes commands from a higher-level control system and translates them into precise voltage adjustments for the excitation winding. This ensures that the motor operates at the desired speed and torque, or that a synchronous generator maintains a stable voltage output.
The “RR” in the part number signifies that the module has been remanufactured. This is a common and cost-effective practice in the industrial sector for maintaining legacy systems. Remanufactured parts are thoroughly tested and repaired to meet original specifications, offering a reliable alternative to new components at a lower cost.
Key Features
- Precise Voltage Regulation: The card provides accurate and responsive control over the excitation voltage, which is essential for stable motor or generator operation.
- Reliability: Built for demanding industrial environments, the module is designed to withstand electrical noise and temperature variations.
- Cost-Effective: As a remanufactured part, it’s a budget-friendly option for extending the life of existing equipment.
Primary Applications
The DS3800NECA/RR is primarily used in heavy industrial applications that rely on large AC synchronous motors or generators. These include:
- Steel Mills: For controlling the large motors used in rolling mills.
- Power Plants: For the excitation control of synchronous generators.
- Pulp and Paper Industry: For managing the speed of large motors on paper machines.
