GE 151X1233DD01SA02 Pitch Battery Charger Assy IS200AEPBH1B
The GE 151X1233DD01SA02 Pitch Battery Charger Assembly (featuring the internal control board IS200AEPBH1B) is an essential power regulation module used primarily in GE Wind Turbine Generator (WTG) control systems. It is responsible for continuously charging and maintaining emergency pitch control battery backup systems, ensuring blade pitch positioning during utility grid loss or emergency shutdown scenarios.
Unique Product Description
The 151X1233DD01SA02 assembly integrates power conversion hardware with the dedicated IS200AEPBH1B control card. Located within the wind turbine’s hub or pitch control cabinet, this unit converts grid AC power into conditioned 12 VDC / 24 VDC output to regulate emergency battery packs.
By continuously monitoring charging current, terminal voltage, and temperature thresholds, it prevents overcharging and thermal runaway, guaranteeing immediate emergency pitch feathering power when wind speeds exceed safe limits or electrical faults occur.
Product Advantages and Features

Installation and Maintenance
-
Power Isolation: Before servicing, disconnect all AC supply feeds and isolate battery terminal quick-disconnect switches; verify zero voltage using a calibrated multimeter.
-
Mechanical Mounting: Install the assembly vertically inside the pitch control enclosure, using factory torque settings on mounting hardware to ensure proper physical grounding.
-
Wiring Connections: Plug in the AC power input, DC battery output, and signal interface ribbons to the IS200AEPBH1B header pins securely.
-
Maintenance Verification: Periodically inspect terminal connections for thermal discoloration, clear dust accumulation from heat dissipators, and test emergency pitch backup capacity under simulated power-loss conditions.
