๐ง Product Overview
The GENERAL ELECTRIC 446W0696P001 is a DC Pitch Converter identified by the JPC1712151 designation and designed for 20 Nm DC pitch motor applications. It is a power conversion unit used in wind-turbine pitch control systems, where controlled DC power is required to adjust and position the turbine blades.
The unit combines a BAA control circuit board with a CAA power circuit board. The listed continuous output rating is 4.2 kW, with a maximum rating of 12 kW at 80 VDC.
This converter is a specialized wind-power component rather than a general-purpose DC drive. When replacing an installed unit, the complete part number, board revisions, software version, motor rating, and system configuration should be checked.

โ๏ธ Operating Function
The main purpose of the pitch converter is to provide controlled DC power to the pitch motor. The pitch motor changes the blade angle according to commands from the turbine control system.
During normal operation, the converter regulates motor power according to the required blade position. This allows the turbine controller to make relatively small pitch adjustments during power production and larger corrections when operating conditions change.
Pitch control also plays an important role during turbine protection. When a shutdown or emergency condition occurs, the pitch system can command the blades toward a safer position. The exact emergency-pitch sequence depends on the turbine model and overall control architecture.
The BAA control board and CAA power board form the principal control and power sections of this converter. The installed WP1Z/WP5R software configuration should be preserved when replacing a unit with an identical system configuration.
๐ ๏ธ Installation & Configuration
Before replacing the converter, record the complete information from the existing unit.
Recommended checks include:
- Confirm the 446W0696P001 part number.
- Verify the JPC1712151 identification.
- Check the BAA control-board designation.
- Check the CAA power-board designation.
- Record the installed software version.
- Confirm the pitch motor is the correct 20 Nm configuration.
- Verify the DC bus and output requirements.
- Inspect power terminals and control connectors.
- Check grounding and cable condition.
- Confirm cooling paths are clean.
- Compare the replacement unit with the original before energizing.
A converter with a similar physical appearance should not automatically be considered interchangeable. GE wind-turbine pitch systems can depend on specific hardware revisions, firmware, motor ratings, and control-system parameters.
๐ Maintenance Tips
The converter should be inspected as part of the turbine’s scheduled electrical maintenance program.
Pay particular attention to:
- Power-board connections
- Control-board connectors
- DC terminals
- Cooling surfaces
- Cable insulation
- Signs of overheating
- Loose hardware
- Corrosion or contamination
- Abnormal converter noise
- Pitch motor current during operation
- Fault and alarm records
If a pitch fault occurs, do not immediately replace the converter. Check the motor, mechanical pitch mechanism, DC supply, cabling, feedback devices, and control signals first.
For a stored spare, use ESD protection and keep the converter in a clean, dry environment. Avoid moisture, conductive dust, and unnecessary handling of PCB assemblies.
